Answer to Question 1

ANS: C
Diffusion is movement of molecules from areas of high concentrations to low concentrations. Effusion refers to the seepage or loss of blood through torn blood vessels. Osmosis describes the movement of water across a semipermeable membrane from a less-concentrated to a more-concentrated area. Suspensions are mixtures of solutions with undissolved particles or mol-ecules.

Answer to Question 2

ANS: A
Partial pressure of oxygen =  oxygen  barometric pressure, or 0.25  760 mm Hg = 190 mm Hg.
