Question

Which of the following statements is true? A. The kidneys regulate water and blood glucose in terrestrial vertebrates. B. The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates. C. Most humans have one kidney, which regulates water and electrolyte balance, removes nitrogenous wastes from the blood, and eliminates the wastes in the urine. D. The kidneys are paired organs that remove nitrogenous wastes from the urine.

Answer 1

Hello! Your answer would be B, the kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

The kidneys are paired organs (eliminating option C) which function as the body's filter for blood. They extract wastes and extra fluid. This creates urine (eliminating option D).

In the final two choices, option A and option B, option B is the correct one. For option a, blood glucose is regulated by hormones. Therefore, option B is correct.

Hope this helps!
