What is it called when a molecule moves across a semipermeable membrane into a region of high concentration?
a. diffusion

b. active transport

c. passive transport

d. osmosis

Active transport

Active transport is the passage of molecules across a membrane from a region of their lower concentration to a region of their higher concentration—in the direction opposite the concentration gradient. Active transport needs cellular energy to perform this translation
