Ozone in the upper atmosphere has duplicated by

Ozone is the layer of atmosphere found above the stratosphere. It is the layer formed by natural occurring chemical reactions.

Explanation:

It involves ultraviolet radiation coming from the sunlight as well as molecules of oxygen that composes twenty one percent of the atmosphere.

During the reaction, the ultraviolet rays breaks down the oxygen molecule to form two oxygen atoms and then these two oxygen atoms which are highly reactive combines with another oxygen atom to form ozone molecule ().

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
