Answer:
D- study anatomy and physiology of skin, complete required hours of training, and pass both a written exam and a practical exam
Explanation:
During exercise, we undergo respiration. Therefore, we need oxygen and release carbon dioxide and water as waste products. When exercise become vigorous, we only run on anaerobic respiration with little oxygen, then lactic acid becomes a waste product instead of carbon dioxide and water. This occurs due to incomplete breakdown of glucose.
Best answer is C. lactic acid.
D
Gender affects body composition
Answer:
An athlete’s resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm.
That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles.
This means the heart beats fewer times per minute than it would in a nonathlete. However, an athlete’s heart rate may go up to 180 bpm to 200 bpm during exercise.
