The reason you cant breathe under water is because people is made to breathe oxygen, water composes oxygen.
no, they cant stupid
cause you don't have gills but we have lungs to breathe the oxygen in water
mammals cant breathe underwater only some of them like a beaver and the family...
they cant breathe because if we do we can drink the water and possibly choke and die.
From what I know about chemical compunds, there is too much H (Hydrogen) in water for land animals to breathe as there is none in air, or close to it. Also, it doesn't include Argon or Nitrogen.For their counterpart, Water animals can not breathe air(Except for dolphins and lung fish) because they do not reach a sufficient amount of Hydrogen. That's my guess anyway.
Yes. goldfish breathe water so if a goldfish is out of water it cant breathe so it will suffocate
the majority of oxygen is found in water therefore you cannot breathe the oxygen in water
Yes it is water vapour is a gas because a gas is two things 1. Things that people here on earth breathe in (Air) or 2. a non-breathable substance that people on earth cant or don't breathe in (for examle steam people don't breathe) So yes it is a gas we cant breathe and most of the time u cant see it!

Because fish have gills, and breathe water- and I cant!
According to many scientists and researches, people cannot breathe in water because water molecules cannot be absorbed by human lungs. Humans have lungs that do not have enough surface area to absorb enough oxygen from water. Our lungs are more much more adapted to air than water.
they arent because they cant breathe air
