The movement of substances from areas of high concentration to low concentration is known as ____
A
diffusion
B
osmosis
C
active transport
D
selectively permeable
Explanation: 

Detailed explanation-1: -Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy.

Detailed explanation-2: -Diffusion is the movement of particles from the area of high concentration to low concentration.

Detailed explanation-3: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.

Detailed explanation-4: -Diffusion is a physical process in which the net movement of molecules occurs from a region of high concentration to the one of low concentration.
