Major Chemical Properties for Cellular Respiration: We need oxygen at the cellular level for this to be complete. Why do you need oxygen? What is your body trying to do? Your body needs to produce energy‚ which is why you go through these metabolic processes‚ and that’s ultimately why you need oxygen. So we are trying to produce ATP as our energy source. So ultimately your energy cannot be created‚ it only changes form‚ so where does that energy come from in your body? We’re going to convert it into

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
