Regulation coordinates body activities and adjusts them when internal or external environmental changes occur which helps conserve homeostasis in spite of appearance the body. Mitosis and reduction division ar two processes of cell division. Mitosis is the process by which the nucleus of a cell divides to create two newfang led nuclei, each containing an identical facsimile of DNA. Mitotic cell division occurs in all body cells unpack for sex cells. Meiosis is the process of cell division that results in gametes in animals or spores in plants with half the number of chromosomes as the p arnt cell.

Meiosis is a sexual process contradictory to mitosis which is an asexual process. While in mitosis the cell divides once, in meiosis the cell divides twice, yielding iv daughter cells.
