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>

Compare the organisms in the table. what plantlike characteristic does a methanogen share with organisms in the kingdom plantae?
ikadub [295]
Plantlike and methanogen organisms share som similar characteristics, for instance, can both produce their own and can process their made food into energy for different cellular processes such as cell division, repair and maintenance.

Despite this similarity though, the difference lies with the source of energy that get to produce the food. Plantlike organisms use sunlight and UV rays to photosynthesize. Whereas, methanogens use methane where sunlight is not present.
