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>

Bingel [31]

Answer:

SecondOption - "Mid oceanic ridge"

Explanation:  

<em> Mid-ocean ridges are formed by divergent plate boundaries in the ocean. This is where upwelling magma creates new seabed. A diverging plate boundary occurs when two plates move away from one other. Magma rises from deep beneath the Earth and erupts along these boundaries, forming new crust on the lithosphere. The majority of divergent plate borders are undersea, forming submerged mountain ranges known as oceanic spreading ridges. </em>
