For example, look at the circles at each location and the lines extending from them. The circles represent the cloud cover e in the sky, and the lines represent the wind e direction and speed. The symbol Ostands for a clear sky, and the
symbol stands for a cloudy sky. Together with the lines, the symbol Or would mean the wind speed is approximately
35 knots coming from the southeast and traveling toward the northwest.
Look at the locations of the warm and cold fronts you drew in part D. In the answer space, describe the cloud cover, wind
speed, and wind direction expected at these locations. Which US states will be affected?

i think the answer is

mass

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

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
