The movement of molecules from an area of high concentrations to an area of low concentration is
A
Diffusion
B
Osmosis
C
Isotonic
D
Hypotonic
Explanation: 

Detailed explanation-1: -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-2: -Passive transport does not require energy input. An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.
