Answer to Question 1

ANS: D
The diffusion time in the lung depends on the rate of pulmonary blood flow.

Answer to Question 2

ANS: B
Carbon dioxide diffuses approximately 20 times faster across the alveolar-capillary membrane than does O2, because of its much higher solubility in plasma.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
