When the concentration of a substance higher on one side of the cells selectively permeable membrane, certain molecules may move
by osmosis or diffusion through the membrane without the cell using any energy. This process is called A.passive transport
B.active transport
C. Mitosis
D. Replication
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
