Why do you think this happens? What do the results tell you about energy in your body?

a. The respiration-rate pattern was much higher than the circulation-rate pattern because you were breathing really fast.

b. The circulation-rate pattern was much higher than the respiration-rate pattern because you need to get food to your cells to get energy.

c. The respiration rate pattern was similar to the circulation-rate pattern because when you are exercising, you need more food and oxygen. You breathe harder to get oxygen and your blood is pumped more to get the food and oxygen to your cells to get energy.

d. The respiration-rate pattern was much higher than the circulation-rate pattern because you needed to get oxygen to your cells
