The condition of a stable internal environment in an organism is:
Correct answer: C. Homeostasis
- A. Coordination
- B. Organisation
- C. Homeostasis
- D. Integration
Explanation
Homeostasis is the correct answer because it refers to the active regulation of an organism's internal conditions to maintain stability and optimal function. It employs various physiological processes to ensure parameters like temperature, pH, and electrolyte balance remain within a narrow range, crucial for cellular functions and overall health. Unlike coordination, organisation, and integration, which involve interactions and arrangements of structures, homeostasis specifically addresses the maintenance of a stable internal environment.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
