Answer Choices:

Correct Answer:

Tendency of the body to maintain a stable environment

Rationale:

⚖️Homeostasis refers to the body’s innate ability to regulate internal variables like temperature, fluid levels, and pH within a narrow, optimal range.

🧬This regulation is achieved through complex feedback systems, especially negative feedback loops.

🧠The nervous and endocrine systems monitor and respond to physiological changes to maintain equilibrium.
