Detailed explanation-1: -Homeostasis is the maintenance of a stable internal environment. Homeostasis is a term coined to describe the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues, organs, and organ systems.

Detailed explanation-2: -Homeostasis is a resistance to change. For example, homeothermic organisms maintain a constant body temperature in spite of fluctuating environmental temperature. There are many other examples of homeostasis in biology, like the pH of blood and the concentration of ATP in a cell.

Detailed explanation-3: -Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. It is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, this includes the control of: blood glucose concentration. body temperature.

Detailed explanation-4: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.

Detailed explanation-5: -Homeostasis is a mechanism through which a cell maintains a well-balanced internal environment.
