A lot to me we do
We need oxegen for air because if we breath to much CO2 we will die but we need a mix of both.
Oxygen is a gas all animals need to live, but too much can kill, and the presence of oxygen enables combustion (fire).
Spacecrafts need internal oxygen supplies because there is no oxygen in space.
the ocean produces the most oxygen we need
no
Oxygen, of course.
loads of oxigen
A lot to me we do
Squirrels need oxygen, just as humans do, so they breathe in air much the same way as humans do. Squirrel blood cells need oxygen to operate their muscels, bones, and anything else in their body, much the same need for oxygen in humans.
twice as much hydrogen to oxygen
A lot if it
No. There is not such thing as too much oxygen just too much carbon. It is good to have a lot of oxygen so the fish dont die because of no oxygen.
The is not enough information to answer this. We need to know what is burning, how much, and how fast, and how much oxygen we have.
eight liters
Because you don't need to get as much oxygen to your blood for respiriation as you do not need more energy. When you are exercising you breathe faster to get that extra oxygen.
Your cells need the oxygen to function. That's why it's called "cellular respiration."and you blood needs to be oxygenated so it can carry the O2 (oxygen) to other parts of the body.
