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 ...

In pure water, a red blood cell from an animal will swell and burst, but a leaf cell from a plant will not. Which structure in the leaf cell is responsible for this difference? A.) Cell Membrane B.) Cell Wall C.) Mitochondrion D.) Nucleus - correct answer B.) Cell Wall Scientist have found geysers on one of Saturn's moons. The geysers release water vapor containing complex organic compounds, which may indicate the presence of life. Which of the following elements is most likely abundan...
