Regulation, Mitosis, an Meiosis.

Regulation is the life fulfil by which organisms and kiosks respond to our ever ever-changing inseparable and external environment. This is important because an upset in homeostasis in any one of an organisms systems might result in an derangement in the organisms homeostasis. In humans, regulation consists of the endocrine and vile systems. The endocrine system is made up of many organs that farm hormones into the bloodstream. The nervous system carries messages in the form or sum impulses throughout the frame. Hormones and nerve impulses can bring more or less changes in the organism in response to the environment. Regulation coordinates body activities and adjusts them when internal or external environmental changes occur which helps keep on 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 newfangled nuclei, each contain ing an identical imitation of DNA. Mitotic cell division occurs in all body cells still 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 bent cell. Meiosis is a sexual process contrary to mitosis which is an asexual process. While in mitosis the cell divides once, in meiosis the cell divides twice, yielding iv daughter cells. Cells produced by mitosis are diploid, and cells produces by meiosis are monoploid. Crossing-over may occur in meiosis, but not mitosis. In both processes, the chromosomes replicate single once.
