You will definitely die!
you dont die!!
if you dont breath then you die
You Would Sufficate, For There Is No Oxygen In Space.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
It dissolves into the bloodsteam and is used in cells by the mitochondria for respiration.
they dont breathe they go to an under water base were there have oxygen tanks
They breathe too much oxygen. This causes light-headedness. Breathe slowly for awhile or breathe into a paper bag to raise your CO2 .
u breathe out CO2 (carbon dioxide) which is absorbed by plants and used in photosynthesis to create oxygen for us
It happens all of the time, except when you are sprinting. It then switches to fermentation, which doesn't use oxygen. This is because when you are sprinting, you don't get enough oxygen for cellular respiration to occur.
Basically the body, especially the brain needs oxygen to function well. If people don't breathe the brain will be deprived of oxygen causing suffocation and in the long run, death. And sometimes having problems with breathing is very dangerous specially when sleeping. Snoring is the best indication.
porifera dont have lungs or gills so the oxygen diffuses straight into their cells
