NEED HELP ASAP, WILL GIVE #4-6-Base your answers to questions #4-6 on the information below and on your knowledge of biology. Five individuals had their pulses taken in beats per minute (bpm) before and after exercise. The data are shown in the chart below. 4. State one reason why an individual's pulse rate increased during exercise 5. Calculate the average pulse rate before exercise for this group, to the nearest tenth_bpm . 6. State why the individuals in this group have different pulse rates before exercise *

4. (answered below); 5. 66.2; 6. (answered below)

Explanation:

4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.

5. Take average of the number of the pulse before exercise:

(68 + 70 + 54 + 64 + 75) / 5 = 66.2

6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.
