The process of deriving the new drug starts in the laboratory. The chemical formula of the drug are composed in the lab and also called as the vitro testing. This type of testing performed before the drug can be tested on the animals or humans. The vitro testing gives the chemical description of the new drug and formulates the base and additional supplements. After vitro testing is done‚ the vivo testing starts on the animals. This process includes testing to figure out the possible side effects

Biology homework 10.2 1. How are the cells at the end of meiosis different from the cells at the beginning of meiosis? Use the terms chromosome number‚ haploid‚ and diploid in your answer. A: Cells in the begining of meiosis has diploid cells‚ with a full amount of chromosomes. In the end of meisos‚ the four genetically different daughter cells are haploid (gametes)‚ they have half the number of chromosomes. Because of this‚ they are able to fuse with other gametes (ex. egg and sperm) to form

Joseph Wakile Math 110-04 December 12‚ 2014 Final Paper Height vs. Shoe Size I chose two quantitate variables in this study in order to see if they had any linear relationship. The dependent (response) variable was a person’s shoe size in united states meaurements and the independent (explanatory) variable was person’s height in inches. I chose these two variables because I assume before the study that there would be appositive linear relationship between height and shoe size. In other words‚ the
