Quizplus · Accepted Answer

The fact that the shark rectal gland only functions in the presence of ATP molecules indicates that the movement of Na+, K+, and Cl- ions into the gland is an active process rather than a passive one, which rules out choices B and C. Additionally, the ability of the gland to concentrate ions is implied by the fact that it requires ATP to function, so D can also be ruled out. Therefore, the best choice is A.
