The wording of the correct answer choice to the following question is confusing to me:
Na+K+ ATPase is found in epithelial cells that produce urine or other excretions that are hypertonic relative to tissues. Why?
a) To form a hypertonic solution, ions or molecules must be actively transported across their concentration gradients.
b) Cells similar to those found in the shark rectal gland occur in many other species that need to excrete salt (NaCl).
c) The sodium-potassium pump is...
