Normal serum level of hormones is controlled by:
Correct answer: B. Feedback mechanism
- A. Target site
- B. Feedback mechanism
- C. Effector's response
- D. Precursor activation
Explanation
Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range.Based on the explanations provided, the correct answer to the question is option B) Feedback mechanism.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
