Question

what is the end result of diffusion?
a equal concentration of molecules on both sides of the membrane
b unequal concentration of molecules with more molecules inside the cell
c unequal concentration of molecules with more molecules outside the cell

Explanation:

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. The process continues until the concentration of molecules is equal on both sides of the membrane, which is called dynamic equilibrium. Option a describes this end result. Options b and c suggest unequal concentrations, which are not the end result of diffusion.

Answer:

a. equal concentration of molecules on both sides of the membrane
