Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.
Answer:
It is necessary to separate oxygenated and deoxygenated blood separate in mammals and birds to maintain their body temperature. Also, if they both are mixed, the blood will get impure and it would be difficult for the heart to supply impure blood. We also can't live with impure blood so we most probably will die.
The answer is B: Water breaks down into oxygen molecules for respiration.
The correct answer is aerobic conditions.
When you do rigorous exercise, the cells of the muscles require more oxygen and this requirement is met through aerobic conditions.
The body has its own oxygen energy system that manages the presence of the oxygen during movement.
