Both mutant and typical rats initially take about 100 seconds to learn how to open the seed. Scientists are easily able to mutate or crossbreed diseases in the anatomy of the rat since their genetic makeup is so comparable to the human body. They got a huge response from interviews and local people. The researchers also measured gene expression in the brains of male rats lacking MeCP2 as well as controls. This essay will discuss some advantages and disadvantages of the animal testing. Some animals are infected with diseases to see if a drug works. In the pro-animal experiments’ defense, using the rats is not harming humans and developing huge steps in health, making people much healthier and coming up with cures to diseases.

Animal experiments are widely used to develop new medicines and to test the safety of other products. The last method uses a computer modeling system which researchers are able to simulate similar human biological structures and progression of human diseases. PETA. “Caring for her takes too much time and effort.” Is also another reasons. From formulating new cancer drugs to testing dietary supplements, mice and rats play a critical role in developing new medical wonders. 1. A common argument against the use of animals in experiments is that animals are not good models for humans, based on the observation that we are not simply larger versions of lab rats – our bodies (and minds) work differently.
