Each year more than 1 million animals are killed in U.S. laboratories. Animal testing is something that happens all over the world and are used in the “name of science” by private institutions‚ cosmetic companies‚ government agencies‚ and scientific centers. Animals feel just as much pain as humans do. The only difference is that they do not have a voice. Millions animals such as dogs‚ cats‚ rabbits‚ mice‚ rats and many others are victims to this. Animal are living creatures and should not be subjected

Does animal testing work? Yes- 1. Animal testing has helped to develop vaccines against diseases like rabies‚ polio‚ measles‚ mumps‚ rubella and TB. 2. Antibiotics‚ HIV drugs‚ insulin and cancer treatments rely on animal tests. Other testing methods aren’t advanced enough. 3. Scientists claim there are no differences in lab animals and humans that cannot be factored into tests. 4. Operations on animals helped to develop organ transplant and open-heart surgery techniques. No- 1.

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide

Theory Testing The theory that was being tested was the Diet Coke and Mentos Geyser. My children wanted to try and see if we could make the Diet Coke shoot out of the top of the bottle like the videos that they had watched on Youtube.com. How the experiment works is you open a package of Mentos and drop the entire package in the Diet Coke as fast as possible. The faster the Mentos drops‚ the more forceful the Diet Coke Geyser will shoot. What should happen is the combination

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top
