Human beings die in a few minutes if they are not able to breathe, or are deprived of oxygen. If you should find yourself in such a situation, obviously you should attempt to escape from it. Failing that, you will die.
you yawn

Yes, cells die without oxygen.
when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide
You must eat food so u dont starve and so u grow. We must breathe because our brains need oxygen in order for it to work
Venus and Mars are the only other solid bodies in the solar system with atmospheres dense enough to "breathe", but neither contains nearly enough oxygen for a human to survive on.
When you breathe it in, carbon monoxide prevents your blood cells from carrying enough oxygen.
No.
They breathe, with lungs.
Air: 78% nitrogen, 21% oxygen, 1% other. We breathe oxygen and other molecules.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
Oxygen is the end product of photosynthesis,plants need water and,some organic minerals from the soil,chlorophyll and carbon dioxide to undergo photosynthesis and the end product is oxygen which is need by the human.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Yes, because trees produce oxygen for us to breathe, and if we dont breathe, we all will die
No, the m50 mask is not the most effective in confined spaces where there is not enough oxygen in the air to breathe to support life.
When someone have cold then he is not able to get enough oxygen to his lungs so that's why its difficult to breathe
You yawn.
You die
they dont breathe they go to an under water base were there have oxygen tanks
