Question

water crosses the plasma membrane view available hint(s) using a process that requires energy from the cell. against its concentration gradient. through facilitated diffusion or diffusion. through cotransport. through active transport.

Explanation:

Water molecules are small and uncharged. They can cross the plasma membrane via simple diffusion directly through the lipid - bilayer or through aquaporins (facilitated diffusion). This process does not require energy (unlike active transport) and occurs down the concentration gradient. Cotransport involves the movement of two substances in the same or opposite directions and is not how water primarily crosses the membrane.

Answer:

C. through facilitated diffusion or diffusion
