Jon likes hiking. He observes that whenever he hikes up a hill he breathes heavier than when he is on flat ground. Which 2 state
Alekssandra [29.7K]

Answer:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

Explanation:

-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.

<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>

At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.

<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>
