HELP THIS IS DUE IN 1 HOUR (No links or I'll Report) The air you breathe out
A) contains more carbon dioxide than the air you breathe in.
B) contains less carbon dioxide than the air you breathe in.
C) contains more carbon dioxide than oxygen.
D) contains less water vapor than the air you breathe in.

A) contains more carbon dioxide than the air you breathe in

Explanation:

So based on our basic knowledge, we know that we breathe in air, keep the oxygen, and breathe out everything else plus the carbon dioxide we make in our lungs. So A is really the only one that makes sense.

if this is wrong tell me so I can fix it

hope this helps:)

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
