It all contains carbon.
Hopefully thats the answer because you didnt put up the choices.
The correct answer is that it is warmed and moistened already in nose and mouth, at the very beginning, when it enters our body (answer a).
It needs to be filtered and warmed alredy before it enters further, because our internal organs are delicate and a dry, dirty air would cause damage to our lungs and other organs.
3. The answer is false, because protons are positive and electrons are negative. If there are more protons than electrons, then the atom would be positively charged.
The answer is false.
4. The answer is true, because if the number of protons and electrons are the same, then the charges would cancel out, leaving the atom negative.
The answer is true.
I hope this helps. :)
