Question

in the process of diffusion, molecules move from areas where

multiple choice
their concentration is higher to areas where their concentration is lower until an equilibrium is reached.
their concentration is lower to areas where their concentration is higher through specific protein channels or carriers.
their concentration is lower to areas where their concentration is higher until an equilibrium is reached.
their concentration is higher to areas where their concentration is lower using energy from atp.

Explanation:

Diffusion is a passive - transport process where molecules move down a concentration gradient, from an area of higher concentration to an area of lower concentration until equilibrium is reached. It does not require energy from ATP and does not involve specific protein channels or carriers (which are involved in facilitated diffusion or active transport).

Answer:

their concentration is higher to areas where their concentration is lower until an equilibrium is reached.
