AP Biology - Unit 2 Study Guide Questions with Verified Answers Describe diffusion and give some specific examples of molecules which move by diffusion. - The random thermal motion of particles of liquids, gases, or solids. In the presence of a concentration or electrochemical gradient, diffusion results in the net movement of a substance from a region where it is more concentrated to a region where it is less concentrated. - The movement of particles of any substance, so that they tend ...
