How is earth's environment unique in the solar system?

In the entire solar system, the environment of planet earth is unique due to the presence of the atmosphere.

It is responsible for providing carbon dioxide and oxygen which are essential for the presence of life on earth.

Secondly, it helps in keeping the earth warm through the greenhouse effect.

It prevents the entry of harmful radiations of the sun into the atmosphere.

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

the answer is c.) there is a warm front in region a and a stationary front in region b.
