Answer 2

C. to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells

Answer 3

To find the total number of servings Jeremy can make from the value pack, we need to divide the total number of ounces in the value pack by the number of ounces per serving.

The value pack contains 42 1/2 ounces of crackers, which is equal to 42 + 1/2 = 42.5 ounces.

Each serving is 1 1/4 ounces.

To divide 42.5 ounces by 1.25 ounces per serving:

42.5 / 1.25 = 34

Therefore, Jeremy can make a total of 34 servings from the value pack of cheese crackers.
