Quizplus · Accepted Answer

The fact that the shark rectal gland functions only when ATP molecules are present indicates that the movement of Na⁺, K⁺, and Cl⁻ into the rectal gland is an active process. ATP is required for active transport processes, and therefore the movement of ions in this context is likely to be active rather than passive. Therefore, choice A is the best answer.
