Why is homeostasis necessary?
Correct answer
D
Rationale
Homeostasis is essential for the body to maintain internal balance and ensure optimal functioning. It is responsible for regulating temperature to prevent overheating or cooling, controlling pH levels to support biochemical reactions, and managing glucose levels for energy production. Therefore, all the options - maintaining temperature, pH, and glucose levels - are crucial functions of homeostasis.
