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>
Answer: believe the answer is C.

Fighting for Clean Air in our National Parks</h2>
Air pollution is one of the most serious threats facing national parks, harming visitors’ health, clouding scenic views and altering our climate.
The air pollution affecting national parks — and the rest of the country — results from the burning of fossil fuels by power plants, oil and gas development, vehicles, agriculture, industrial emissions, and other sources. NPCA works to make sure our nation’s air laws are strong, to hold polluters and government accountable to those laws, and ultimately, to reduce the air pollution that harms our parks, climate and communities.
<h2>Defending Federal Laws and Regulations
</h2>
The Clean Air Act – which has helped improve air quality throughout the nation and the National Park System – is now under consistent threat as the Environmental Protection Agency works to roll back regulations, attack the use of science and offer polluters loopholes. NPCA advocates to defend and strengthen the clean air laws that protect park skies. We speak out for science and guard against policies driven only by politics and private industry.
<h2>Holding Polluters and Governments Accountable
</h2>
Picture park skies free of pollution. While this sadly isn’t the case today, NPCA strives to make sure that parks are on the right track and that air pollution harming parks is reduced. We do this by helping to secure strong state plans to limit haze-causing and climate-altering pollution, and by defending existing plans – in court, if necessary.
<h2>Advocating for Pollution Reduction</h2>
Clean air laws are meaningless if polluters and the government don’t follow them. NPCA vigilantly monitors for sources that violate their permits or when officials aren’t following through on the safeguards in place to protect parks. We also look for opportunities to collaborate and work in state, local or regional processes to prevent threats of new pollution and help reduce harmful emissions.
