PLEASE MARK AS BRAINLIEST

Explanation:

I'll answer the 15th question first so you can understand much clearly.

15. When there is no enough oxygen, the body undergoes anaerobic (without oxygen) respiration.

14. Muscle cramps occur due to the accumulation of lactic acid during the breakdown of glucose when body undergoes anaerobic respiration.
