Question
- A. Because it is influenced by external temperature and humidity
- B. Because it is regulated by the kidneys
- C. Because it only occurs during exercise
- D. Because it is a voluntary process
Answer
The correct option is Because it is influenced by external temperature and humidity. 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 Because it is influenced by external temperature and humidity. Because it is influenced by external temperature and humidity 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).
Common mistake
Misunderstanding Water Loss Control
Students often think that water loss through the lungs and skin can be precisely controlled like other bodily functions.
Emphasize that water loss through the lungs and skin is influenced by environmental factors and body temperature, making it variable and not precisely controlled.
