You inhale them but your lungs only absorb the oxygen- they are exhaled again when you breathe out.
Nothing - they are "breathed out" with your exhale.
The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration. So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
we breathe in air as a whole which contains both carbon Di-oxide and oxygen but we exhale out carbon Di-oxide and other usefulness gases
Gases have no definite volume or shape. The air that you breathe, the helium in a balloon, and the neon inside the tube in a neon light are gases.
Expired air is air that you breathe out of your lungs.
Nothing - they are "breathed out" with your exhale.

The air we breathe contains 78% Nitrogen and 20% Oxygen. The remainder is Helium and other gases
they cant breathe because gills do not support air on land where many other gases are present
By putting harmful gases into the air
the lungs will moves down when breathe out air
Gases mix together when they contact each other. There are no immiscible gases like there are immiscible fluids.

Animals breathe a mix of gases including;NitrogenOxygenCarbon dioxideWaterArgon
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
