Which term describes a normally balanced condition of the body resistant to change?

Equilibrium
Homeostasis
Allostasis
Stability

The correct answer is: Homeostasis

The term that describes a normally balanced condition of the body resistant to change is homeostasis. Homeostasis refers to the complex processes that maintain the internal environment of an organism within a narrow, stable range, despite external changes. This includes regulation of various physiological parameters like temperature, pH, hydration, and electrolyte levels. The body's systems work together to ensure that any deviation from the normal range is corrected through feedback mechanisms, ensuring overall stability and health. Equilibrium often implies a state of balance but does not encompass the constant adjustments made by the body to maintain internal stability. Allostasis refers to the process of achieving stability through change, emphasizing the adaptive mechanisms the body employs to cope with stressors rather than maintaining a constant state. Stability, while related, is a broader term that may refer to various systems and their resistance to change, but it does not specifically denote the biological processes involved in maintaining internal balance.
