To determine: The relationship between homeostasis and allostasis.
Introduction: The human body has various vital physiological mechanisms toward their respective environmental stressors. Their ultimate goal is to maintain a constant and uniform internal environment for the body. For survival, the stability of the internal environment, which is independent of the external environment, is found to be necessary. The disease would occur if the body does not respond appropriately to maintaining internal stability.

Explanation of Solution
The process of regulation and maintenance of the body in a relatively stable condition with the internal environment of the body is referred to as homeostasis. It is a state of equilibrium that is carried out through the physiological mechanisms of the body.
The process of attaining stability through the behavioral or physiological changes of the body is referred to as allostasis. It is essential to maintain the internal viability in the course of the changing environmental conditions.
Thus, homeostasis describes certain conditions, and allostasis is a process of achieving homeostasis through adaptive change, which is necessary for the well-being and survival.
