Over 100 million animals are burned‚ crippled‚ poisoned and abused in U.S. labs every year. 92 percent of experimental drugs that are safe and effective in animals fail in human clinical trials because they are too dangerous or don’t work. Labs that use mice‚ rats‚ birds‚ reptiles and amphibians are exempted from the minimal protections under the Animal Welfare Act (AWA). Up to 90 percent of animals used in U.S. labs aren’t counted in the official statistics of animals tested. The

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C‚ what could be the reason? The reason why water did not boil at 100°C could be because we are not at sea level; the pressure could be lower. B. While heating two different samples of water at sea level‚ one boils at 102°C and one boils at 99.2°C. Calculate the percent error for each sample from the theoretical 100.0°C. 1st sample 1.96% error 2nd sample 0.81% error C. An unknown

Macbeth and ‘The Laboratory’? In this essay I will be writing about female power in Macbeth and ‘The Laboratory’. I will be analyzing them both to show the similarities and differences between the two pieces. Both include a strong‚ crafty and dominant female character and Shakespeare and Browning explore these characters fully and in great detail. Both the speaker in ‘The Laboratory’ and Lady Macbeth strive to maintain their innocent images. The speaker in ‘The Laboratory’ wants to kill

Laboratory Science Abstract 85% of all medical decisions are based on the results of clinical laboratory testing. Medical laboratory science is the use of clinical laboratory tests to detect‚ diagnose‚ monitor and treat disease. Blood‚ tissue and body fluid can be chemically analyzed and examined for foreign organisms and abnormalities. This information is then used by the medical team to make decisions regarding medical care. Laboratory scientists have made important contributions to the development

Pathology laboratories study disease. Diseases are mainly diagnosed through analysis of tissue‚ body fluid and cell samples. Pathology laboratories can also study the predicted or actual progression of particular diseases. Pathology is a field of general inquiry and research so addresses four components of disease. These components are cause‚ mechanisms of development‚ structural alterations of cells and the consequences of the changes. If a hospital sends off a sample to a pathology laboratory‚ when

Safety measures in the chemistry laboratory The mentors are responsible for instructing the competitors as to the risks to which they are subjected when working in a chemistry laboratory‚ as well as to the basic safety measures‚ and first aid. Specific behavioral and safety measures must be obeyed to prevent accidents. Rules in the lab: * Use protective clothing all the time (e.g. lab coat and safety glasses) * Use a hair band to keep your hair away from your face. *
