Detailed explanation-1: -Homeostasis is the ability to maintain internal stability in an organism in response to the environmental changes. The internal temperature of the human body is the best example of homeostasis.

Detailed explanation-2: -Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equillibrium or stability within its internal environment to compensate for environmental changes.

Detailed explanation-3: -Cellular and organismal homeostasis Homeostasis in an organism or colony of single celled organisms is regulated by secreted proteins and small molecules often functioning as signals. Homeostasis in the cell is maintained by regulation and by the exchange of materials and energy with its surroundings.

Detailed explanation-4: -Homeostasis is a dynamic equilibrium that is maintained in body tissues and organs. It is dynamic because it is constantly adjusting to the changes that the systems encounter. It is an equilibrium because body functions are kept within a normal range, with some fluctuations around a set point.

Detailed explanation-5: -Homeostasis can be defined as ‘preserving constancy in the internal environment’.
