Answer to Question 1

ANS: A
Diffusion is the tendency of the molecules of a substance (gas, liquid, or solid) to move from a region of high concentration to one of lower concentration.

Answer to Question 2

ANS: C
Heroin has no currently accepted medical use in the United States and there is a lack of accepted safety guidelines for its use under medical supervision. Morphine and pentobarbital are both Schedule II controlled substances; Lomotil (diphenoxylate with atropine sulfate) is a Schedule V drug.
