Hormonal coordination in humans
Question
- A. To increase blood glucose levels
- B. To control blood water concentration
- C. To stimulate muscle contraction
- D. To regulate body temperature
Answer
The correct option is To control blood water concentration. This answer is correct because it matches the approved learning objective to explain (HT only) how ADH release is controlled by negative feedback to maintain blood water concentration in the subtopic Maintaining water and nitrogen balance in the body (biology only).
Explanation
The correct option is To control blood water concentration. To control blood water concentration is correct because it directly supports the approved learning objective to explain (HT only) how ADH release is controlled by negative feedback to maintain blood water concentration. This belongs to the subtopic Maintaining water and nitrogen balance in the body (biology only) within Hormonal coordination in humans, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Maintaining water and nitrogen balance in the body (biology only).
Common mistake
Misunderstanding ADH Function
Students often confuse the role of ADH with other hormones, thinking it directly increases blood water concentration rather than controlling its release through negative feedback.
Clarify that ADH regulates water reabsorption in the kidneys and that its release is controlled by negative feedback mechanisms that respond to blood water concentration levels.
