T<span>he cell requires oxygen, and eukaryotic cells are expensive to run. they require a lot of energy and nutrients, and oxygen is one such component. the oxygen is necessary for aerobic respiration, which allows the cell to do a lot, including evolve, proliferate, adopt new niches, habitats, biochemical habitats, sustain life in extreme conditions, and perhaps eventually co-operate with other cells and create multicellular life. Multicellular life is virtually impossible without aerobic respiration. </span>
Step 1: glucose is broken down into 2 molecules of pyruvate
Step 2: Completes breakdown of carbon dioxide, makes small amounts of ATP, provides electrons
Step 3: electron transport chain, chemiosmosis; energy from electrons-- produces 32 ATP
In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
Answer AND Explanation:
As the population increases, the amount of resources are depleted. Inadequate resources makes the population growth to stop. With a high population, death rate increases due to starvation and diseases which spread more easily in a large population. There may be a decrease in birth rate due to fewer matings and abortions resulting from social stress.
