Question

question 5 1 pts what is the definition for diffusion? (1:17) a. movement of molecules from an area of high concentration to an area of low concentration b. movement of molecules from an area of low concentration to an area of high concentration c. free movement of molecules no matter what concentration

Explanation:

Diffusion is a natural process where molecules move from a region of higher concentration to one of lower concentration to achieve equilibrium. This is driven by the random motion of molecules and does not require energy input for the net movement in this direction.

Answer:

A. movement of molecules from an area of high concentration to an area of low concentration
