Quizplus · Accepted Answer

The table shows that the concentration of Na⁺, K⁺, and Cl⁻ in fluid eliminated from the shark rectal gland is higher than their intercellular concentration. This indicates that the rectal gland is able to concentrate these electrolytes, suggesting a possible function of ion regulation in the shark's body. Options A, C, and D are incorrect because the table does not provide any evidence to support these functions.
