Question

When molecules move down the concentration gradient, molecules are moving

from *
an area of low concentration to an area of a higher concentration
areas that are equal in concentration
an area of high concentration to an area of a lower concentration
O areas with low concentration of water to an area of a higher concentration of water

Answer 1

(When molecules move in this way, they are said to move down their concentration gradient.) Three common types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Simple Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
