Question
- A. By increasing water retention
- B. By excreting more urine
- C. By storing it in fat cells
- D. By converting it into glucose
Answer
The correct option is By excreting more urine. This answer is correct because it matches the approved learning objective to explain why removing excess water, ions and urea is important for internal balance in the subtopic Maintaining water and nitrogen balance in the body (biology only).
Explanation
The correct option is By excreting more urine. By excreting more urine is correct because it directly supports the approved learning objective to explain why removing excess water, ions and urea is important for internal balance. 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
Understanding Internal Balance
Students often state that removing excess water, ions, and urea is only important for preventing dehydration.
Emphasize that removing these substances is crucial for maintaining homeostasis, which includes regulating blood pressure, electrolyte balance, and preventing toxic buildup in the body.
