Question

I need help checking my work. MEDALS!!! will be awarded. I chose C.

Kidneys process nitrogenous wastes by
A) seperating water from nitrogenous wastes by passive diffusion.

B) using cells to actively pump water across a membrane.

C) storing the wastes as uric acid until they can be eliminated.

D) pumping ions across membranes to separate water from waste products.

Answer 1

The answer is "A", seperating water from nitrogenous wastes by passive diffusion because it only makes sense to separate the bad stuff (wastes) from the water which in turn processes the waste through and out the kidney.
