4. What is the feedback mechanism in the endocrine system that helps maintain hormone balance?
- A. Positive feedback, where a hormone stimulates its own release
- B. Negative feedback, where a hormone suppresses its own release
- C. Cascade effect, where one hormone triggers the release of another
- D. Dual hormone system, where two hormones work together
Correct answer: B
Rationale: The correct answer is B: Negative feedback, where a hormone suppresses its own release. In the endocrine system, negative feedback is a crucial mechanism that helps maintain hormone balance. When hormone levels rise, they signal the body to decrease further hormone production, preventing an excess. This ensures that hormone levels stay within a narrow range, promoting stability and homeostasis. Positive feedback (option A) would lead to an amplification of hormone release, which is not ideal for maintaining balance. Cascade effect (option C) involves a sequential activation of hormones but does not directly regulate hormone levels. Dual hormone system (option D) refers to two hormones working together but doesn't specifically address the feedback mechanism for maintaining hormone balance.

- A. It is unstable and tends to crystallize
