Homeostasis

 3.1. Definition

Homeostasis refers to the ability of an organism to maintain stable internal conditions despite changes in external environments.

3.2. Mechanisms of Homeostasis

Organisms employ various mechanisms to regulate their internal environment:

Negative Feedback Loops: Counteract changes (e.g., regulation of body temperature).

Positive Feedback Loops: Amplify changes (e.g., childbirth).

3.3. Importance of Homeostasis

Maintaining homeostasis is crucial for:

Optimal functioning of enzymes and metabolic processes.

Overall health and survival of organisms.
