- C. It happens continuously, regardless of activity level.
- D. It is the main method of water loss in the body.
Answer
The correct option is It happens continuously, regardless of activity level.. This answer is correct because it matches the approved learning objective to explain why water loss through the lungs and skin cannot be precisely controlled in the subtopic Maintaining water and nitrogen balance in the body (biology only).
Explanation
The correct option is It happens continuously, regardless of activity level.. It happens continuously, regardless of activity level. is correct because it directly supports the approved learning objective to explain why water loss through the lungs and skin cannot be precisely controlled. 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).
