Which of the following is true of an amine group? It is the carbon-containing portion of an amino acid.
O It is the unique chemical structure attached to the backbone of each amino acid.
It represents the acid group attached to the central carbon atom.
It is the oxygen-containing portion of an amino acid.

Iam not sure but to me it with be a or dsorry if i was late! hope this ! : )if you really want me to find out the answer that is correct tell me and i will do more research but the a or d makes sense to me.

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.

Oi oi oi oi oi oi  i think it is true
