Which of the following best explains diffusion?Which of the following best explains diffusion? a. movement of molecules from an area of high concentration to an area of low concentration b. movement of molecules farther away from equilibrium c. movement of molecules from where there are fewer of them to where there are more d. exchange of nonpolar molecules for polar molecules

The correct option is' a'.

Diffusion is the movement when molecules move from higher concentrated area to lower concentrated area.

Explanation:

When a substance moves from higher concentrated area to a lower concentrated area, is called as diffusion.

It mainly occur in liquid and gaseous substance as their particle can easily move from one place to another.

Diffusion is important for living being as water enters into the plant body through the process of diffusion and during respiration, when the concentration of carbon dioxide is high then it diffuse out through the cell membrane and enters into the blood.
