WebEach tiny advantage gained by favorable variation gives a species an edge over close competitors, predators, parasites, or even prey. The only method that will allow a co-evolving species to maintain its own share of the resources is to also continually improve its fitness. WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair.
