Biology Osmosis Lab Report Sample Essay Example

Science Osmosis Lab Report Sample Paper Science Osmosis Lab Report Essay Introduction CO is moved from the blood to the lungs, where is breathes out. The admission 02 and the equal end of CO in the lungs and is called gas trade with the earth or in any case breath (URL). In physiology breath is characterized as the vehicle of 02 in the body from the outside air to the cells inside tissues and the vehicle of CO the other way. Consequently the essential capacity of the breath in human body is to convey 02 to all pieces of the body so as to deliver vitality for the group of life form and expel squander item out of this. URL). This capacity is performed by the respiratory framework. In the investigation we managed breathing and were marked to the concoction factor or factors support for breath and managed the 02 and CO. For the most part in the investigation was multiple times breathing, distinctive air quality each time, which contains an assortment of air from the relaxing. At that point measure the 02 and CO noticeable all around which was gathered. At one time was bre athing barometrical air and the other multiple times was breathing 02 and CO separately. An assortment of articles among which the clock for time estimation, mouthpiece for breath, geometer for estimation the 02 in the blood, a packs for gathering air and two other sack who have 02 and CO separately (URL). The outcomes were acquired after the recuperation gas blends were estimated in the research center through a machine estimating instruments in this gas blend. The technique was utilized to comprehend the explanations behind which breathing happens just as the particular components causing it. The trial recognized these elements by the varieties in air admission and exhalation. Utilizing this strategy we figured out how to characterize the perfect air blend for sound relaxing. Materials and Methods: A great deal has been composed and said about the control of breath in the human body and numerous course readings and researchers have managed this fundamental issue in medication. The y express that breath in sound individuals is for the most part constrained by CO fixations present in the cerebrum and blood vessel blood. Current research is centered around points of interest and subtleties of this substance breath control. Science Osmosis Lab Report Essay Body Paragraphs This analysis recorded the paces of 02 and CO focuses. Elevated levels of CO in the blood are normally noxious, hence it is desirable over have them at the most reduced potential levels. Incomprehensibly it is the expansion of CO fixations which controls taking in the external breath framework, the essential capacity of the human body (URL). At the main phase of the examination, an individual inhaled air thought a mouthpiece and so as to inhale just from the mouth with the assistance of the mouthpiece, we utilized a clasp. In this phase of the examination, breath was taken from ordinary air which was inhaled from room conditions as we as a whole breath day by day, with air containing 80% Nitrogen, 20% Oxygen and 0% CO . Breathing of ordinary air was taken for one moment and afterward the individual inhaled the air held his holding for however much time as could reasonably be expected and having the nose cut on the button. He figures out how to hold his breath seconds before he smothe red the air blew air into a sack; this second is called Pane time. At that point the sack was given to the research facility specialist so as to pass the quality of the pack goes into a gas investigation. From the examination of the sack air we have the rates of pip and APPC individually. The units which gave the goals are mug. In the principal investigation, the outcomes were 38, 9 mug CO and 104, 78 mug 02. The second part the trial was rehashed as already with a couple of contrasts. In particular, with the assistance of the mouthpiece and the nose cut as before was taken hyperventilation for one moment. At that point the breath was hold for whatever length of time that conceivable, specifically 61 second, after that get the air inside he pack for a gas break down with the assistance of the research center professional, as in the past. The level of 02 for this situation was 102. 19 mug, while the CO was 26 mug. In the third piece of the analysis we utilize an extraordinary pack co ntaining 5% CACM, where the mouthpiece was associated with the sack which contained the 5% CO and the breathing was taken from the sack for one moment. As beforehand with the colleague of mouthpiece and nose cut, the breath was hold as far as might be feasible, explicitly 37 seconds. Tests of the air in a sack product taken again as before in the gas break down to dissect the new rates. The rates which were taken were 111. 11 mug for 02 and 49 mug for CO The fourth time the trial was around a similar path as the past occasions as in the past; with the distinction breathing was taken from a pack containing 40% 02 for one moment, with the assistance of the mouthpiece. The breath hold was rehashed as far as might be feasible, to be specific for a considerable length of time and for this situation the paces of the air gathered after the gas examine, were 140. 25 mug 02 and 55 mug CO The normal of these outcomes was acted in the table beneath alongside the chart. The rates we got were 02 140. 25 mug and CO 55 mug. In test with the exception of the mouthpiece and the nose cut utilized likewise the geometries to watch the oxygen present in the body and a stopwatch to quantify the hour of breath and time of breath holding. Normal of these outcomes was performed and the table beneath alongside the diagram. Results: Experiment I Pane Time (sec) I Pane Time (sec) I APPC (mug) I APPC (mug) I pip (mug) I pip (mug) | Saturation | Saturation I MEAN I SD I MEAN I SAID MEAN SD I MEAN SD I Normal Air | 59 1 91 38,9 1 6,81 104,78 | 20,95 | 96 1 51 Hyperventilation 97 | 24 | 26 1 3,91 102,19 120,95 1 95 141 co 12417149 131 111,11 | 6,13 196 131 02 | 86 191 55 131 140,25 1 1486 1 98 141 The table records the consequences of the analysis. Explicitly it’s representing the normal APPC (mug) and pip (mug) in the four breaths made during the test. On the chart the incomplete weights of CO and 02 are thought about at limit in the four distinct gas blends that the subject needed t o take in. The timeframe it took the subject to arrive at limit is recorded without fail and is in any case called as sheet time, just as the % 02 immersion is recorded with the assistance of a heartbeat geometer. Watch the table vacillations f the outcomes depending each time the gas blends are evolving. Specifically we note that the consequences of pip are higher than different costs as opposed to the aftereffects of APPC which are the most minimal. Every one of these varieties are because of the expansion and lessening of pip and APPC, each time is extraordinary and furthermore the need of each living being changes as per its’ needs. The investigation was to breathing four unique gases, for example, exists in the table like Normal air, Hyperventilation, 5% CO and 40% 02 for one moment each time. At that point follow two charts with the aftereffects of the table we got from the trial. The principal chart shows the normal of APPC and pip. The red line shows the normal of the consequences of pip that were gathered taken care of. Each spot shows the specific measure of pip found subsequent to breathing various gas blends. The blue line likewise shows the normal aftereffects of APPC and each spot shows the specific measure of APPC found in the wake of breathing various gas blends. In particular, we see that the estimations of the red line are higher as it ought to be since we need oxygen to endure. The ordinary degrees of halfway weight of 02 in breathed out air, very still are 120 mug for the oxygen and for carbon dioxide 27 mug. Anyway the sums in he try watched are particularly not quite the same as should be expected levels on the grounds that the gas blend levels of carbon dioxide and oxygen were consistently extraordinary each time and furthermore this is on the grounds that the breath was held for quite a while before breathing out. The primary purpose of the diagram showed diminished paces of oxygen from ordinary while the paces of carbon dioxide expanded. That is because of breath which kept happening in any event, when the individual was holding its breath hence as there was no pace of end and there was no more oxygen took in carbon dioxide levels expanded since it is a result of breath. The subsequent point likewise shows that the measure of pip is higher than the measure of APPC. Now we had rates from hyperventilation. We see that both the measures of pip and the pace of APPC are lower than the past breath however ordinary levels. With hyperventilation the oxygen levels are lower from each other condition in light of the fact that the subject is taking short and quick breaths to fulfill it is prompt requirement for oxygen. Lower measures of oxygen result to bring down measures of carbon dioxide. The third point shows the paces of breath when a %5 of CO was acquainted with the gas blend. Now the levels pip and APPC have expanded from he past breaths. The oxygen levels are decreased contrasted and the degrees of carbon dio xide which is ordinary since the gas blend contained 5% of carbon dioxide. Watch these outcomes in light of the fact that now there was a huge increment in the carbon dioxide bringing about oxygen to be marginally expanded in light of the fact that there is a requirement for the life form to remain at balance levels generally so more oxygen take-up was required. In the fourth area the outcomes are more raised than the various focuses, yet likewise is expanded and contrasted with ordinary degrees of breathed out air very still. The consequences of this point were gotten after the breathing f 40% more oxygen than typical. With this breath levels expanded since a lot of oxygen was taken in and along these lines the pace of carbon dioxide expanded in light of the fact that is a side-effect of breath. In the subsequent chart, the green line shows the % pace of 02 contrasted with the multiple times of breathing various gases. Notice that the first and third point at the chart, when the su bject was breathing typical air and afterward when a 5% of CO was added to the blend, are a similar sum. Accept that is on the grounds that both oxygen and carbon dioxide increas

As the clock struck 6:00, Gabriel and Uriel were practically finished with their undertaking. â€Å"We must carry our creation to Him for last preparations.† Uriel clarified. As the two blessed messengers coasted through the mists towards Him with a little infant young lady in their arms, they arrive at a huge white stone structure roosted in the focal point of paradise.

Ways of Seeing - 1748 Words

Ways Of Seeing (Chapter 7) In today’s world, marketers and advertisers are fighting for every spot they get to display their ads and market their products. The ultimate aim is to get as much exposure as possible. This in turn, they hope, will translate into sales. The literature â€Å"Ways of Seeing – Part 7† underlines the theory of publicity. I chose this literature because it elucidates the backbone of marketing and advertising – publicity. It interests me because designers and advertisers revolve their careers around for many years in order to obtain ‘Publicity’. ‘Kodak sells film but they doesn’t publicize film. They publicize memories’ (Theodore†¦show more content†¦Berger highlights this difference by giving examples of Mrs. Siddons by Gainsborough and Andy Warhol’s Marilyn Monroe which, although have outstanding elements of a painting but fail to be ‘objects of envy’. When looking into the differences between publicity and oil paintings, another consideration is the tense with which it is referred to. While the subject of oil paintings associate to the moment they are created in, the contents of publicity refer to the possibilities of a superior future enhanced by the product. Also, oil paintings are a possession of permanent nature or precisely, a depiction of the present lasting for the future, which in case of publicity is only the probable imagination of the future. Lastly, there come monetary differences. Oil paintings are created for that class of the society who posses wealth. Conversely, publicity is designed for that class of people whose lives would be superior by the presence of the publicized product. In spite of having these variations, publicity and oil paintings share a common visual language. Berger supports this resemblance by various comparisons of oil paintings and publicity images placed side by side, which vary only because publicity includes some quotations.

Revolutionary Movement free essay sample

The reasons for the American Revolutionary Movement are diverse and numerous; however, one reason stands above them all: economics. Ever since the first settlers began to colonize the United States, economics have been present as the foundation for the country. Our society today is derived from money matters just as it was in the time before and during the Revolution. The British fighting the French and Indian War was a base for strong financial changes that led to the Revolution.This was closely followed by the Declaratory Act that allowed the taxing of the colonies and the Intolerable Acts made by the British. We will write a custom essay sample on Revolutionary Movement or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They all had strong influences in the economics of the country that led to the Revolutionary War. In 1754, the British fought the French for the final of four wars in what we know as the French and Indian War. It was a fight to see who would rule in North America, and it was eventually won by the British. Despite their victory, the British were forced into debt, and their solution to get out of it involved one thing: taxing the colonies.This led to the formation of the Greenville Taxes. Two of these, the Quartering Act and the Stamp Tax, brought uproar from the colonists. The Quartering Act forced the colonists to house and feed British Soldiers with no additional money given to them. Many of the colonists didnt have the money to feed the soldiers, so it caused them to go into debt, which affected the financial side of the communities because the people were becoming so poor. After the Quartering Act, the British brought on the Stamp Tax.This was the first direct tax on the colonists, and it got them all riled up. A group known as the Sons of Liberty was formed and they led a boycott against the British taxing claiming that there should be no taxation without representation. The tax changed the economics of the colonies, causing them to lose money rapidly, but the boycott came back in retaliation against the British. Because the British were no longer getting money from the colonists to pay off their debt, their finances were suffering triggering the repeal of the tax.The Sons of Liberty appealed to the king about the Stamp Tax, so the king repealed the tax using the Declaratory Act. This act still allowed the king to tax the colonies, and he made full use of that fact. One year after passing the Declaratory Act, the king brought around the Townsend Act and put a tax on dead, paper, paint and tea, as these were the items most economically important to the colonists at the time. After much debate, all the taxes were revoked except for the one on tea.Nevertheless, the damage to the economy of New England was done, and the wealth of the country was declining rapidly, angering the colonists. The settlers in the colonies didnt agree with the British taking all of their hard-earned money, and so they were slowly building up to the American Revolution in retaliation. This led to the Boston Tea Party which was once again spear-headed by the Sons of Liberty. England ere very angry with the colonists destroying all their tea, and instead of giving the colonist what they wanted, they jacked-up the tax price on the tea and made them pay for what they had ruined. Once again the economy was dropping because all of the money was going to the British. With every act performed by the British that involved money, the colonists were becoming angrier with their mother country which caused them to strike back. The final acts made by the British were the real turn. These are known as the Intolerable Acts, and they are what finally brought the colonists to the Revolution. The Intolerable Acts are made up of several things done by the British, but the two that made the most impact were the ones that involved money.The British passed the Boston Port Bill which closed the port in Boston. This devastated the economy as the colonists could no longer import or export goods from one of their biggest ports. It caused inflation in prices and a riot within the colonies. Already angry with the British, the colonists now saw everything that England did as unforgivable and a reason to fight. Another one of the most influential Intolerable Acts was the increase quartering of troops.This happened because the charter stating that the colonists no longer had to house soldiers Was revoked, and more troops were sent to keep the over-ambitious colonists under control. Fuming with anger at once again having to pay for not only them, but at least one other person as well, each colonist was finally thrown over the top, and they started to fight to gain their own country. From the time the British fought the French in the French and Indian War to when they instated the Declaratory and Intolerable Acts, economics became the main force driving the colonists into the American Revolution.Not only did England try to take advantage of the new colonies to earn money, but it seemed to neglect the fact that it was throwing the people into debt. Having to give all of their money to Britain, the colonists became infuriated, so they fought back and it led to the American Revolution. Economics were and are very important to every country, so it is understandable that inflation in prices and higher taxes could have led the American Revolutionary Movement, and it is even easier to accept that it was what primarily drove to colonists to begin fighting back.

Introduction to an Oligopoly Market

Introduction to an Oligopoly Market When discussing different types of market structures, monopolies are at one end of the spectrum, with only one seller in monopolistic markets, and perfectly competitive markets are at the other end, with many buyers and sellers offering identical products. That said, there is a lot of middle ground for what economists call imperfect competition. Imperfect competition can take a number of different forms, and the particular features of an imperfectly competitive market has implications for the market outcomes for consumers and producers. Oligopoly is one form of imperfect competition, and oligopolies have a number of specific features: Several large firms - Oligopolies generally consist of a few large firms, and this is part of what sets them apart from competitive markets. Similar or identical products - While it is possible to have an oligopoly with slightly differentiated products, firms in oligopolies usually sell non-differentiated products. Barriers to entry - There are barriers to entry into an oligopoly, making oligopolies different from competitive markets with a large number of relatively small firms. In essence, oligopolies are named as such because the prefix oli- means several, whereas the prefix mono-, as in monopoly, means one. Because of barriers to entry, firms in oligopolies are able to sell their products at prices above their marginal costs of production, and this generally results in positive economic profits for firms in oligopolies. This observation of markup over marginal cost implies that oligopolies do not maximize social welfare.

Employment Relations Essay Example | Topics and Well Written Essays - 2500 words - 1

Employment Relations - Essay Example A few of the evidences such as CIPD (2011) provides a clear statement that there are very less organisations wherein the unions do not have any existence. It is also evidential that the labour unions have a high influence on the development of the business organisations. Justifiably, the trade unions have played a decisive role in the UK for developing the employment relationship with the help of introducing the procedure of collective bargaining and allowing the employers to design favourable policies for the employees (CIPD, 2011: 3-4). In an organization wherein both employers and unions are the part of work process, it can be stated that the employment relationship ensures successful running of business at large. With regards to the aforesaid subject, this essay is being prepared with an intention of gaining an insight about employment relationship, which prevails between the employers and the labour unions. The study has been conducted on this subject with reference to various literatures reviewed by different authors. In the conclusive part of the essay, a study has been made on the prevalence of employment relations in the organisations with unions and without the unions as well. Employment relationship, as mentioned in the earlier section is one of the prime aspects of every business organisation. In this similar context, it can be apparently observed that the unions have a significant role to play in building up of the employment relationship. For instance, as per the notion of Guest (2004: 542), employment relationship is considered as one of the wide framework of rights and responsibilities of both the employers and the employees towards forming a healthy relationship in order to reap significant benefits. Guest (2004: 542) also stated that in the ancient industrialization society of the UK and the USA, there was high prevalence of unionism in the majority of

Introduce the two companies and explain the difference between a b2b Essay

Introduce the two companies and explain the difference between a b2b company and a b2c company - Essay Example is a B2B company since it provides manufactures and supplies microprocessors necessary for computer manufacturing companies such as Dell, HP, Samsung, Sony etc. On the other hand Dell is a B2C company since the products manufactured by this company is sold directly to the consumers. B2B and B2C companies differ in terms of marketing mix, product ranges, marketing communication, pricing and distribution Product, Price, Place and Promotion are considered as the four major elements of marketing mix (Ritcher, 2012). Intel is one of the major semiconductor chip manufacturers in the world. It supplies many types of semiconductor chips including microprocessors to prominent computer manufacturers as well as electronic devices manufacturers. Therefore, the company is targeting only the major manufacturers of electronic devices such as Dell, Sony, HP, Lenovo etc. Unlike B2C companies, B2B companies or Intel is operating through channel partners in different market. For example, LG, Lenovo, Dell and Zenith are some of the channel partners of Intel in different markets (Mody, 2007). Intel has a variable pricing strategy across the world. Since the company enjoys monopoly in some markets, it has the ability to fix the prices of its products in such markets. As in the case of B2C companies, Intel also use various promotion strategies to get more market share. â€Å"In 2006 Intel launched a fi ve-year campaign known as the ‘World Ahead Program’. This initiative is geared toward an increase in digital literacy, research, and development†(Flores, 2008). Dell on the other hand has a wide range of products such as workstations, desktops, desktops, tablets, etc. The company is marketing its products directly to the consumers with the help of advertising and promotion strategies. Promotion plays a big part in Dell’s marketing mix even though it plays less significant role in Intel’s marketing mix. Variable pricing mechanisms were implemented by dell in different markets based

The persuasion used by both Lady Macbeth and the male speakers Essay Example for Free

The persuasion used by both Lady Macbeth and the male speakers Essay Shakespeare portrays Lady Macbeth as a strong, independent character, who employs cunning intellect to manipulate and control her husband and to gain illegitimate power and authority. Using varied techniques, Lady Macbeth predominantly targets Macbeth’s masculinity and likens him to a â€Å"woman†; taunting him in order to provoke the desire to disprove her doubts and assumptions. Macbeth decides not to â€Å"bear the knife† on Duncan, as he is both his is both â€Å"his kinsman and his subject†. Nevertheless, Lady Macbeth shifts the power in their relationship, taking the typically male, authoritative role and persuading Macbeth to â€Å"play false†, using his devotion to her and â€Å"ambition† to fulfil the witches’ prophecies. Lady Macbeth tactically finds similarities between herself and the witches. In doing so, she assures herself that she is too a significant influence and retains substantial authority over Macbeth, where she can analyse his personality and potential. Breaking feminine stereotypes, Lady Macbeth’s character redefines sixteenth century expectations and expresses Tudor â€Å"fears† of women overstepping their â€Å"natural† boundaries. Feminising Macbeth On becoming aware of her new title, thus her potential to greater power, Lady Macbeth begins to rid herself of her feminine attributes and bestows them upon Macbeth in order to persuade him to â€Å"catch the nearest way† and seize the role as king. Nevertheless, as a woman Lady Macbeth lacks the authority and ability to undertake the murder and compensates by rationalising with herself, and her husband, in order to instigate the persuasion necessary for the central murders. She accuses Macbeth to be â€Å"too full o’th’milk of human kindness† implying weakness and absence of â€Å"ambition† to forcefully take the role as king. Macbeth is â€Å"full† of â€Å"milk†, a factor associated with maternity and femininity. In referring to Macbeth as nurturing and feminine, Lady Macbeth undermines her husband’s masculinity and takes the power in the relationship, fuelling her own â€Å"ambition† to become â€Å"unsexed† or masculine, and seizing authority where she can evaluate her husband’s character. As a new mother in the sixteenth century, women would be substantially weakened and susceptible to â€Å"illness† after and during child birth; as a result, would too lack the â€Å"ambition†, to sustain an additional life and feed the child with the â€Å"milk†. Moreover, in making reference to â€Å"milk†, Lady Macbeth insinuates that Macbeth is ‘milky’; a renaissance term used to describe cowards. Having recently returned from battle, Macbeth abolished any â€Å"fear†, to fight in Duncan’s name. Insinuating he is a â€Å"milky† creates further â€Å"ambition† to prove his wife wrong, therefore, in attempt to persuade Macbeth, Lady Macbeth labels him and questions his loyalty to her, his â€Å"dearest partner in greatness†. Anaemia In describing her husband as â€Å"green and pale†, Lady Macbeth continues to criticise and undermine him. Such a pallor would betray green sickness, and in the sixteenth century, more commonly known as hypochromatic anaemia; symptoms included weakness and lack of energy, showing that Lady Macbeth believes her husband to be lacking both the capability and motivation to carry out the murder. Furthermore, the sickness was associated with woman, specifically due to blood loss during childbirth, linking to her previous allusions from Macbeth to a new mother, who would be â€Å"full of..milk†. â€Å"Green† being a colour commonly associated with envy, presents Macbeth as inferior to other men, defying Lady Macbeth’s desire for his superiority and kingship. By revealing her husband’s jealousy- and therefore his insecurity regarding his own influence- Lady Macbeth questions whether he has the qualities required to rule, such as confidence in his own power. Lady Macbeth’s description of her husband is persuasive by routinely emphasising the qualities he lacks and his negative aspects, presenting him as unfit to achieve his destined kingship. â€Å"Take my milk for gall† Although the witches are depicted as the only paranormal beings in the play, Lady Macbeth attempts correlates with the witches’ supernatural mannerism and pleads to the â€Å"spirits†, demanding them to â€Å"take her milk for gall† to further eradicate her femininity and assert her desired power of the supernatural. The meaning of â€Å"take is ambiguous, either implying Lady Macbeth wishes to be rid of the â€Å"milk†, that she perceives as â€Å"gall†, poisoning her with compassion and nurture, hence preventing her from assisting Macbeth in the â€Å"deed†. Moreover, she denotes that her â€Å"gall† is pre-existing in her â€Å"breasts†, suggesting she already holds an element of â€Å"cruelty†, too shown in the witches’ nature. Correlating with the witches, thus convincing herself she is somewhat supernaturally powerful, allows Lady Macbeth to rid herself of any submission shown to Macbeth, as a weak, delicate woman and like the witches, gain supremacy over her husband to then persuade him to â€Å"catch the nearest way†. As a woman, Lady Macbeth would be â€Å"full of milk† appealing to her nurturing attributes and impeding her from committing the â€Å"cruelty† needed to succeed to greater power. She begs the spirits to â€Å"take† her â€Å"milk†, therefore ridding her of her feminine attributes and affection she may have held for her guests, as their â€Å"honoured hostess†, presenting a sense of false hospitality which is also shown in the image of the â€Å"poison chalice†. As his â€Å"kinsman and his subject†, Macbeth offers his hospitality and loyalty to Duncan, represented through the image of the â€Å"chalice†, only to be â€Å"poisoned† by the supernatural expectations and Lady Macbeth’s hunger for superiority. Having plotted against the king, a man appointed by God, Macbeth displays his remaining religious principles, describing Duncan as â€Å"heaven’s cherubin† expressing admiration of Duncan’s leadership and is almost worshipful of him; perhaps in the attempt to save himself from â€Å"deep damnation† that may follow if the supernatural realm should fail him. Nevertheless, as Lady Macbeth gains further influence over him, she alters his â€Å"golden opinions†, turning him into a â€Å"beast† who wholly disregards any respect he had for Duncan. Lady Macbeth further accentuates Macbeth’s negative qualities, such as his indecisive nature and refers to him as â€Å"coward in thine own esteem†, questioning his masculinity and implying he is too afraid to act upon his desire to achieve his destined kingship. Macbeth’s â€Å"esteem† shows his strong desire to be king and how highly he values the crown. Despite his high regard of the crown, Lady Macbeth believes having â€Å"esteem† and â€Å"ambition† within is not enough to gain him the â€Å"ornament of life†; implying the crown â€Å"wouldst be† his greatest asset and achievement. Calling Macbeth a â€Å"coward† further emphasises the struggle Lady Macbeth faces in gaining all of her husband’s loyalty, as he begins to review the Duncan’s â€Å"virtues† and favourable attributes, thus creating doubt in his ability to murder him. However, by stating Macbeth is too afraid to â€Å"catch the nearest way†, Lady Macbeth allows him to deny her initial claim, reinstating his â€Å"hope† of killing the king and deliberately using her doubt to convince him to kill Duncan as he wishes to â€Å"become a man†. Lady Macbeth de-genders The â€Å"strange sisters† being the most powerful influence over her husband, sustains Lady Macbeth’s desire to disassociate herself from gender and be affiliated to the witches’ power. Mid-sixteenth century productions of â€Å"Macbeth†, presented the witches as bearded, powerful characters who consequently opposed their female characteristics. Appearing neither male nor female, grants the witches superiority over Macbeth. They are liberated from the stereotypes of female subordination and expectations of masculinity, like strength and dominance. This gives them freedom and the power to do as they please and therefore dominance over all other beings. To take the authoritative role in the relationship and become equivalent to the witches’ influence, Lady Macbeth begs the spirits to â€Å"unsex† her, removing her feeble, feminine qualities that may â€Å"bring forth† compassion she once had for Duncan, as her guest and subsequently becoming â€Å"more than man†. Employing her new found supremacy over her husband, Lady Macbeth becomes a source of strength and inspiration who â€Å"pours her spirits in thine ear†; an image holding both supernatural and medicinal significance. Most commonly associated with Egyptian healing methods, pouring homeopathic remedies in people’s â€Å"ear†, was thought to heal them of psychological and physical ailments; in Macbeth’s case, his weakness, cautious nature and sentimental attachment to Duncan. On the other hand, the image opposes the concept of healing, due to the supernatural connotations of. Lady Macbeth influences her husband with her corrupt intensions by â€Å"poisoning† him with the â€Å"spirits† who posses her â€Å"gall† and hence eradicating Macbeth’s remaining sentiment possessed for Duncan. Modality When reasoning with herself, Lady Macbeth avoids directly complimenting her husband, and only saunters on the potential that he â€Å"wouldst be great† taking a patronising tone in attempt to draw out his feminine attributes, and disapproval of being seen as inferior to a woman. Macbeth’s own uncertainty is prominent, as he â€Å"fears† the religious and lawful outcome if he â€Å"should fail†. Lady Macbeth is eminently frustrated by his indecisive nature and angst, and with regard to the witches’ prophecies, she specifically highlights Macbeth’s expectations, and too expresses her own doubts in his capability to kill and become king. Lady Macbeth suggests he â€Å"wouldst† be â€Å"highly†, using modal references to imply the possibility of alternative outcomes. In doing so, she taunts him and â€Å"dares† him to oppose her, consequently diminishing her doubts. Furthermore, his expectations were appointed to him by women , the â€Å"strange sisters† whom held power over him and foresaw his fate. Lady Macbeth re-raises the fact he was inferior to them, contributing to his desire to prove her wrong. Cat i’th’adage Heightening his inferiority to Duncan, Lady Macbeth likens him to a â€Å"poor cat i’th’adage†. Using to a common aphorism of the cat who wanted fish but did not want to get wet, expresses Macbeth’s unwillingness to dirty his hands to â€Å"catch the nearest way† and taunts his lack of desire to seize the â€Å"ornament of life†. By calling him â€Å"poor† displays Lady Macbeth’s supercilious demeanour and her value of her power over him, mocking him with pity and encouraging him to ascend to greater power. Describing Macbeth as a â€Å"cat† degrades his status and â€Å"dares† him to oppose her claims, while also alluding to Duncan’s ownership of him. Cats are commonly associated with witchcraft and are under the witches’ power- as is Macbeth, who is under their influence and expectations to consummate the prophecies. Furthermore, cats are easily startled, re-raising Macbeth’s fear and distinc t awareness of the consequences of treason, further accentuating his weakness and lack of â€Å"ambition†.

Compare Carol Ann Duffys Valentine to Andrew Marvells To His Coy Essa

Compare Carol Ann Duffy's Valentine to Andrew Marvell's To His Coy Mistress In this assignment I will be comparing two love poems Carol Ann Duffy's 'Valentine' to Andrew Marvell's 'To His Coy Mistress'. The poem 'Valentine' was written is the twentieth century and in it the speaker uses onion as a metaphor to show her love. The poem 'To His Coy Mistress' was written in the seventeenth century and is about the poet trying to persuade his Mistress to sleep with him. 'Valentine' by Carol Ann Duffy is very different to any other love poem as you would expect to read something romantic, instead she writes about an onion. The poem is divided into four main stanzas and each stanza tells us something new about the relationship and in between there is one or two words in sentence which helps you think about want she is trying to say. The poem starts off with a positive statement 'Not a red rose, or a satin heart'. She states that she will not give her lover a normal valentine present. The poet has chosen to give her lover an onion. She uses the onion as a metaphor for her love. The poet says 'I give you an onion, it is moon wrapped in brown paper,' with this she creates mystery and makes her lover think the reason for this weird present. 'It promises light, like the careful undressing of love.' Here she is telling her lover that their relationship can still survive and she refers to sex as she talks about the undressing of love. The second stanza starts with the use of the word 'Here' makes the reader feel that the poet is in control and that she is actually giving something. She continues with the extended metaphor 'it will blind you with tears',' like a lover, not only will the onion make your eyes w... ...ere are many points we can see this from, but the main one is what the poem does not rhyme which means that it was not thought about when being written, 'To His Coy Mistress' is written to persuade so it is only about one topic 'sex' and there are many religious comparisons to make this look right. This is also done by the poem being divided into three main parts 'if', 'but' and 'so'. The first part of the poem is 'if', the speaker talks about if only he had all the time in the world. This helps him to define his reason to why he is trying to sleep with her quickly as possible. The second part of the poem is about 'but', the speaker talks about the reasons he wants to sleep with her and about how time is running out. In the third part of the poem the speaker goes on to 'so', and dedicates the last part of the poem to tell her that they should have sex.

What contribution did Edward Jenner make to medicine?

The person I have chosen to write about is Edward Jenner. He was born in 1749 and is famous as the first doctor to introduce and study the smallpox vaccine. I am interested by his work as it was the basis of the science of immunology, resulting in many medical advances, the benefits of which can be seen in medicine today. Smallpox is a virus spread through coughing, sneezing and physical contact with an infected person. Epidemics broke out in Britain every few years, resulting in many deaths. In the eighteenth century a method of inoculation was introduced to Britain. This reduced the chance of dying from smallpox, yet it carried with it many risks. Whilst offering inoculations against smallpox, Edward Jenner, a doctor from Gloucestershire, discovered that those who had previously suffered from cowpox were less likely to catch smallpox than those who hadn't. He subsequently came up with the idea of using cowpox, a mild disease, as a method of prevention. In an attempt to prove this theory, Jenner conducted an experiment in which he took matter from a cowpox sore and inserted it into a boy through two cuts. After slight uneasiness in the following days, the boy was perfectly well. He was then inoculated with smallpox matter, which was repeated again several months later, but no disease followed on either occasion. After completing the experiment 23 times, he came to the conclusion that ‘cowpox protects the human constitution from the infection of smallpox'. Although Jenner was unable to prove his theory, his vaccination saved many lives. He recorded and published his findings himself as there was much opposition to vaccinations at first. This was because some people found it hard to accept anything new, especially when there was no explanation as to why it worked. Also, if his vaccinations proved to be a success, doctors would lose the income they received from providing inoculations. As well as this, some people saw the vaccination as dangerous. This was for reasons including doctors accidentally infecting patients with smallpox instead of cowpox or using infected needles, both of which resulted in many deaths. However, Jenner's work paid off, and in 1840 the British government provided vaccination free of charge. The main reason that I am interested in Jenner is that he was able to come up with a successful method of prevention of smallpox without advanced technology. His observations and experiments provided accurate results leading to life saving treatment, which I feel was one of the biggest medical achievements up until that time considering that smallpox had previously been one of the biggest killer diseases. He was not put off by the ‘less than enthusiastic' view of the public, choosing to record his findings personally in hope that they would one day be accepted and prove to be useful (which is what finally happened). Also, his work greatly contributed to later medical advances. It was the basis of immunology, which was to be pursued with success by Pasteur and others half a century later, helped by technological advancements. His observations had a large influence on the declaration of smallpox as an eradicated disease in 1980 by the World Health Organisation. In conclusion, Edward Jenner was a man who was able to make a large contribution to the advancement of medicine and prevention of death from smallpox. This, in my opinion, makes him a prominent and essential figure in history.

Directional Selection Is One of Three Types of Natural Selection

Directional selection  is a type of  natural selection  in which the  phenotype  (the observable characteristics) of the species tends toward one extreme rather the mean phenotype or the opposite extreme phenotype. Directional selection is one of three widely studied types of natural selection, in addition  to  stabilizing selection  and  disruptive selection. In stabilizing selection, the extreme phenotypes gradually reduce in number in favor of the mean phenotype, while in disruptive selection, the mean phenotype shrinks in favor of extremes in either direction.   Conditions Leading to Directional Selection The directional selection phenomenon is usually seen in environments that have changed over time. Changes in weather, climate, or food availability can lead to directional selection. In a very timely example connected to climate change, sockeye salmon have recently been observed shifting the timing of their spawn run in Alaska, likely due to rising water temperatures.   In a  statistical analysis of natural selection, directional selection shows a population bell curve for a particular trait that shifts either further left or further right. However, unlike  stabilizing selection, the height of the bell curve does not change. There are far fewer average individuals in a  population that has undergone directional selection. Human interaction can also speed up directional selection. For example, human hunters or fishermen pursuing quarry most often kill the bigger individuals of the population for their meat or other large ornamental or useful parts. Over time, this causes the population to skew toward the smaller individuals. A directional selection bell curve for size will show a shift to the left in this example of directional selection. Animal predators can also create directional selection. Because slower individuals in a prey population are more likely to be killed and eaten, directional selection will gradually skew the population toward faster individuals. A bell curve plotting species size will skew toward the right when documenting this form of directional selection.   Examples As one of the common forms of natural selection, there are plentiful examples of directional selection that have studied and documented. Some well-known cases:   Pioneer evolutionary scientist Charles Darwin  (1809–1882) studied what later became known as directional selection while he was in the  Galapagos Islands. He observed that the beak length of the Galapagos  finches  changed over time due to available food sources. When there was a lack of insects to eat, finches with larger and deeper beaks survived because the beak structure was useful for cracking seeds. Over time, as insects became more plentiful, directional selection began to favor  finches  with smaller and longer beaks that were more useful for catching insects.Fossil records show that black bears in Europe decreased in size during periods between continental glacial coverage during the ice ages, but increased in size during the glacial period. This was likely because larger individuals enjoyed an advantage under conditions of limited  food supplies and  extreme cold.  In 18th and 19th century England peppered moths who had been predominantly white in order to blend in with light colored trees began to evolve into a predominantly dark species in order to blend in with an environment that was becoming increasingly covered with soot from Industrial Revolution factories.
