​

Answer 1

Answer:

yes

Explanation:

Reason for my answer

The cells in our bodies require a continual supply of oxygen to survive. The air we breath normally provides sufficient oxygen to our lungs to replenish the oxygen our blood circulation system delivers to our cells. When in an environment without air, or with insufficient oxygen in the air, tanks holding compressed air or oxygen can be used to maintain the oxygen level our bodies need for respiration.

Air contains oxygen. In the body oxygen is reacts with glucose in a process cal aerobic respiration. This reaction is the source of the energy that powers the human body. Without oxygen this cannot occur and we would quickly run out of energy and die.
