Your Answer:
•In condition (a), breathing rate increases since muscles work hard during exercise & need more oxygen and also produce more carbon dioxide.

•In condition (b), during non-REM sleep, you breathe slowly and regularly. But during REM sleep, your breathing rate goes up again.

Answer 2

a) When we do exercise then our breathing rate increases because oxygen is needed to burn calories more efficiently. Since, the blood picks up oxygen in the lungs and demand for oxygen increases during exercise, the lungs must work harder. With a faster breathing rate, more oxygen is picked up at the lungs for delivery to the working muscles.

b) When we sleep we breath slowly and regularly. But during REM sleep your breathing rate goes up again. Whenever you are sleeping your Oxygen levels are lower and your Carbon dioxide levels are higher because your level of breathing goes slightly down.
