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.
You don't use all of it but you do use a lot of it i am not 100% certain how much you use though
i might say probably fishes to breathe and also aquatic plants
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.
It is probably more accurate to say that you breath in air, a mixture of gases which contains about 21% oxygen and 0,04% CO2, and you breath out a mixture of gasses which contains a far greater concentration of carbon dioxide than you inhaled (about 5% of the mass of all the exhaled gas).
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
