What is NOT true about cellular respiration? SELECT AN ANSWER It is necessary for survival. It is a process where energy in food is changed into energy that can be used by the body's cells. It is a process that is not needed if the organism eats the energy-rich food directly. Humans are capable of this process.

it is a process that is not needed if the organism eats energy-rich food directly.

Explanation:that is untrue.

hope my answer helped I tried<3

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
