Answer to Question 1

ANS: A
If the blood PCO2 is high, creating high levels of H2CO3, then the kidneys excrete greater amounts of H+ and reabsorb all of the tubule filtrate's HCO3 back into the blood.

Answer to Question 2

ANS: A
Both HCO3 ions and Na+ ions are reabsorbed with water whenever H+ ions are secreted into the tubular filtrate.
