Answer to Question 1

C

Answer to Question 2

When pH is low, hydrogen ion levels in the blood are high and also in the interstitial and peritubular fluid. Hydrogen ion competes with potassium ion for the sodium countercurrent exchanger in the tubules. As hydrogen ion secretion rises (which compensates for the acidosis), potassium is retained and hyperkalemia develops. If severe enough, muscle cramps and cardiac arrhythmias result.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
