If you are speaking in terms of blood oxygen saturation, then no, life is not sustainable at this level. Normal adult blood oxygen saturation is 96%-100%
The air around us contains 21% oxygen at sea level. So speaking in terms of 63% oxygen in the air then survival would not be a problem as this would be triple the amount you currently breathe.
22% oxygen at sea level
Yes. The air we breathe every day is 21% oxygen.
Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.
No. The planet has no oxygen.
not long
Oxygen was the first element used by humans the most prominent elements in the body are hydrogen OXYGEN nitrogen and carbon. You have probably heard that you body is made up of 65 percent water well you are also made up of 65 percent oxygen. I know that does not equal 100 percent but water is H2O which is hydrogen squared and Oxygen. Oxygen is in water. We need oxygen to live.
No. Too cold, no oxygen, too much pressure.
No, a person cannot live without a head. The head contains essential organs such as the brain, which controls vital functions like breathing. Oxygen machines cannot replace the functions of a head in sustaining life.
90 percent because it is possible to live without your intestine.
you won't live. you have to have all of your heart to live. it's impossible to only have a fraction of your heart anyways.
Im not entirely sure on the oxygen level but i know that they do need a lot of oxygen in order to live. There are many cases in which tadpoles are found floating on the surface of the water gasping for air because they can not achieve the amount of oxygen needed in the water. In order to fix this a filter may be needed to its tank. Hope this helps!
The different order of blood between a live person and a dead one would be the lack of oxygen in the blood. It becomes stagnat like a pool that doesn't flow.
