There are approximately 200 different types of cells in the human body although all cells are dependent on other cells to perform body functions. explain how your model supports this statement

Group of cells construct the organs of human body which helps our body to function properly.

Explanation:

All living things are made up of cells. Human body is constituted of approximately 200 cells. Not every cell functions equally. Different cells function differently. However, the cells which has the same work to do they combine to form tissues, and groups of cell constructs human organs like heart, lungs etc. which functions together to control the body.

So it can be said that though not directly but cells are indirectly dependent on each other to perform body function.  

c. is the correct answer

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.
