Animal Testing

Is Animal Testing/Research Necessary for Advancing in Medicine? Introduction: Animal testing involves using non-human animals for scientific procedures. Animal research can be used for a number of things such as developing new drugs to improve health, learning about animals and the human body, aiding scientific advances and ensuring other products do not harm humans. Vaccinations against diseases like polio, rabies, measles, mumps and rubella were developed because they were tested on animals. Also the development of open-heart surgery and organ transplants depended on operations done on animals. In 2006 approximately two million animals were used in procedures. Animals that are normally used in tests and experiments include: rats, mice, rabbits, monkeys, guinea-pigs, cats, dogs, fish, birds, pigs, horse, sheep and hamsters. This pie chart shows the types of animals used in procedures. A large proportion of experiments are conducted on mice. (1) Those who are extremely against animal testing (animal rights activists) would refer to it as 'vivisection'. This means the 'cutting up of animals'. They refer to animal testing being morally wrong and cruel. However this is just one view, others are not so against animal testing. Others may believe that animal testing is necessary for some purposes for example medicinal purposes yet not for beauty products. Methods of

Aseptic Technique.

Aseptic Technique * Wipe the bench you are working on with disinfectant - this kills all the bacteria that may already be on the bench at the start of the experiment. The bench also needs to be wiped down at the end of the experiment. * Wipe tray that you will put all the equipment on with disinfectant - this is done to kill all the bacteria that may already be on the tray so that the sterilised equipment is not contaminated. * Sterilise all equipment - the equipment used is put in an autoclave which sterilises it so that bacteria on the equipment are killed and the equipment is ready to be used. * Light Bunsen Burner near equipment - this is done to create an up draught of air away from the bench to prevent contamination of cultures. * Wash your hands with antibacterial soap - this will get rid of any bacteria that may already be o your hands. Other safety precautions: * Wear safety goggles to protect your eyes * Wear a lab coat to protect your clothes from being contaminated with the cultures. * Cover all cuts Procedure . Collect all sterilised equipment and put on the tray that has already been disinfected. 2. Collect 10cm3 of the water sample in a sterile test tube and cover. 3. Prepare 4 serial dilutions of the original (10 , 10 , 10 , 10 ). Make sure a different pipette is used for each sample or else the samples will be contaminated. 4. Label the

The Use Of Enzymes In Industry

The Use of Enzymes in Industry Skills I and J Enzymes are extremely useful and therefore are used in many industries. The reason for them being so useful is that they work quickly and efficiently to speed up the rate of many different reactions without going through changes themselves; this also makes them reusable.[5]This is all down to them being biological catalysts. The food industry is a major industry which relies on enzymes and probably the main place in this country where they are used. Throughout the industry there are numerous different areas which involve enzymes to make the process quicker. Some of these are; Fruit, Dairy, Brewing, Starch and Baking. Throughout the process of making fruit juices enzymes are used; as fruits contain pectins which are polysaccharides and cause cloudiness in the juices. To reduce this pectin and increase the amount of juice degrading enzymes are added at the pressing stage as the fruits are being modified. Therefore customers get better juice which isn't as cloudy and the company's gain more profit as they are making a larger quantity of juice.[7] Dairy products like cheese are made with the help of two enzymes, pepsin and chymosin. As cheese is made from raw material milk, the milk has to be warmed and these two enzymes added in order for the milk to form 'curbs and whey'. The product of this is a cloudy thick liquid containing

Wuthering heights

Thesis: Wuthering heights and the importance of the traditional ghost story 'My fingers closed on the fingers of a little, ice-cold hand! The intense horror of nightmare came over me: I tried to draw back my arm, but the hand clung to it' (Page 20) In this extract Lockwood thought he had a dream, he remembers that he 'turned and dozed' and dreamt again, but the above extract shows that this was different from any other dream, it is much more realistic and increasingly frightening. This leads the reader to believe that this really is not a dream and that a supernatural being is causing this entire disturbance. The importance that this has to the novel is that it adds an element of excitement and mystery to the novel, rather than Lockwood just having a dream about a ghost by the end of the extract, they believe that their really was on there. What makes this part of the novel all the more stirring is the fact that there is evidence that this really was a ghost at Lockwood's window. For instance Lockwood says that that name of the ghost was 'Catherine Linton': '(Why did I think of Linton? I had read Earnshaw twenty times for Linton)' (Page20) This is to say that in any dream one would not expect to dream about someone they had never met before, and they would expect for their dreams to be a collaged combination of all the things that had happened to them. In this particular
