Answer to Question 1

A

Answer to Question 2

When blood calcium levels are low, parathyroid hormone is secreted into the blood, which stimulates the activation of vitamin D, the reabsorption of calcium in the kidneys, and stimulates osteoclast cells to break down bone and release calcium into the blood. Vitamin D, in turn, works with parathyroid hormone to increases calcium absorption in intestines. When blood calcium levels are too high, calcitonin is secreted, which inhibits the activation of vitamin D and prevents calcium from being reabsorbed in the kidneys, as well as inhibiting osteoclast cells from breaking down bone.

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.
