C)Osmosis

Question

Quizplus · Accepted Answer

Facilitated diffusion is a type of passive-mediated transport, meaning it does not require energy to move molecules across a cell membrane. The process is facilitated by carrier proteins that help molecules move down their concentration gradient from an area of high concentration to an area of low concentration.

Answer: C
 Osmosis is a type of passive-mediated transport that involves the movement of water molecules across a cell membrane. Water moves from an area of low solute concentration to an area of high solute concentration in order to create equilibrium.

Facilitated diffusion and osmosis are both types of passive-mediated transport, so answer A and C are both correct. Active-mediated transport (choice B) is a different type of transport that requires the use of energy to move molecules against their concentration gradient.
