select all the correct answers. jon likes hiking. he observes that whenever he hikes up a hill, he breathes heavier than when he is on flat ground. which two statements explain why this happens? sensors in the brain detect a lack of oxygen. the muscles in his body need more energy and therefore more oxygen. the body has too little carbon dioxide to maintain function. the body is using carbon dioxide instead of oxygen to make energy. blood pressure has decreased, so less blood is being pumped to the muscles.

Answer

Brief Explanations:

When hiking uphill, the body's muscle - work increases. Muscles need more energy, and cellular respiration requires oxygen for energy production. So, the body needs more oxygen. Also, sensors in the brain can detect a relative lack of oxygen and signal the body to breathe more heavily.

Answer:

Sensors in the brain detect a lack of oxygen. The muscles in his body need more energy and therefore more oxygen.
