Oxygen keeps animals alive, Nitrogen is not much use.
they are nitrogen oxygen argon and carbon dioxide
Air is mainly a mix of oxygen and nitrogen. Oxygen is the part your body uses- the good stuff.
When we inhale air, we breathe in nitrogen along with oxygen. Our body uses the oxygen for cellular respiration to produce energy, while the nitrogen is mostly exhaled back out without being utilized by our bodies. Nitrogen makes up about 78% of the air we breathe, but our bodies do not have a biological need for it.
Air is approximately 80% Nitrogen, 19% oxygen and 1% others
About 80% of air is nitrogen (20% oxygen)
The air is primarily composed of nitrogen and oxygen. About 78% Nitrogen, Oxygen 21%.
Ambient air is about 21% Oxygen, 78% Nitrogen and 1% Mixed Gasses. Our body uses about 4% Oxygen to stay alive so what comes out is 17% Oxygen and 4% Carbondioxide.
nitrogen-65% and oxygen-30 to 34%
Air is primarily composed of nitrogen (about 78%) and oxygen (about 21%).
The air is made up, mostly, of oxygen and nitrogen.. Air is 78 % nitrogen, 21 % oxygen, about 1 % argon, and a whole raft of other gases present in even smaller amounts..
Air is composed of more than 2 gases: 78% Nitrogen 21% Oxygen 1% of other gases lime Carbon Dioxide, Ozone, Argon etc.
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
