Answer 1

Homeostasis is the process by which the body adjusts to changes and maintains equilibrium. It involves detecting changes in the internal or external environment and responding to bring the body back to the set point.

Step-by-step explanation:

Homeostasis is the process by which constant adjustment to changes in the body occurs, and equilibrium is maintained as body functions remain within a certain range without any fluctuations. The goal of homeostasis is the maintenance of equilibrium around a specific value called a set point.

When a change in the internal or external environment occurs, it is detected by receptors, and the body responds by adjusting its activities to bring the value back toward the set point.
