Which best explains why viruses are not classified by Linnaean taxonomy?
A) Viruses do not contain any genetic information or a cell wall.
B) Viruses share many characteristics with several of the kingdoms.
C) Viruses cannot reproduce outside a host cell and are therefore nonliving.
D) Viruses lack a protein coat and any metabolic activity.

C) Viruses cannot reproduce outside a host cell and are therefore nonliving.

Explanation:

Viruses cannot reproduce outside a host cell and are therefore nonliving. Their cell walls are created from different substances and bacteria has an RNA polymerase that archaea lacks.

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 think it is dna, i'm not totally sure but i think it might be.
