It is not rues at all. Most of the gas inhaled is not oxygen it is nitrogen.
The reason you cant breathe under water is because people is made to breathe oxygen, water composes oxygen.
Kind of. Fish need to breathe water to get oxygen. If they can't breathe, or if the water has too little oxygen dissolved in it, the fish will die from lack of oxygen (I would say suffocate; you may say drown).
They 'breathe' through the stomata on both surfaces of the leaf. The stomata are extremely tiny 'holes' that you can only see under a microscope. They are usually found on the underside of the leaves.
Fish, like all animals, require oxygen to live. They get their oxygen by filtering it out of the water using their gills, so you could say that they breathe water.
No, not all the oxygen you inhale is used by your body. About 20% of the oxygen we breathe is used by the body for energy production through respiration, while the remaining 80% is exhaled back out into the atmosphere.
It's inaccurate because we actually breathe in a mixture of gases, with oxygen being the most abundant at about 21%. When we breathe out, the air we exhale still contains a significant amount of oxygen along with other gases like nitrogen and some carbon dioxide. The exchange of gases occurs in the lungs, where oxygen is taken up by the blood and carbon dioxide is released.
All I can say is that when you breath in, you take in air and extract the oxygen. When you exhale you're letting out the nitrogen that was with the oxygen in the air. The oxygen then goes to your blood. How this happens? I can't say. Sorry.
They do... Raccoons are Mammal's, as are Humans... And like humans, they have lungs, a heart, kidneys, a bladder and a brain... as they have a nose, eyes, ears and a mouth. It is almost safe to say that anything furry, has lungs.
Yes, This can be simplified to say that oxygen is an element.
Because what you breath in is air (which is 80% nitrogen) not oxygen and what you breath out is air with a slightly changed proportion of gases as compared that which you breathed in.
somr people may say not much but that's a lie hospital use pure oxygen for life support you can breathe in pure oxygen for 12 years strait and not die
No.. Only if they say true story on them..
