Question

describe the movement of molecules in the illustration. a molecules are moving from a lower concentration to a higher concentration. b molecules are moving from a higher concentration to a lower concentration. c molecules are moving from a higher concentration to a lower concentration and then from a lower to higher concentration d molecules are moving from a lower concentration to a higher concentration and then from a higher concentration to a low

Explanation:

In the illustration, the net flow of molecules is from an area with more molecules (higher concentration) to an area with fewer molecules (lower concentration). This is the basic principle of diffusion, where molecules move down their concentration gradient.

Answer:

B. Molecules are moving from a higher concentration to a lower concentration.
