Animals have long played an important role as research animals in the field of Science by human kind since Ancient Greeks‚ when Aristotle used animals as a dissection. Animals are used in research and experiments by scientists to advance human knowledge and find cures to diseases such as asthma. In my opinion‚ animals are needed for scientists to conduct researches and experiments. Firstly‚ animal models are used to test drugs. This is because it will lower the risk of effects on humans when the

In 1966‚ the Animal Welfare Act was passed which “...regulated the sale‚ transportation‚ and handling of many animals used in research…” (Driscoll and Finley 3)‚ but the act does not cover rats‚ mice‚ fish ‚ and birds which make up around ninety-five percent of tested animals (“Should Animals Be Used” 3). Government approved acts are proposed and confirmed to ensure the safety of animals‚ but organizations soon find their way around them.

The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

Animal Testing Every year‚ over 100 million animals are painfully put to death because of animal testing. Experimentation on animals goes way back since the beginning of time. Typically it is conducted for advancement in scientific research‚ to test products and food before going out into the market‚ to find treatments or test medical drugs‚ and to protect people and the environment. Animal experimentation has been a controversial issue for quite some time‚ but has yet to be put to an end. Vivisection
