Viruses are made up of either dna or rna surrounded by a coating of protein. when the two main substances that make up a virus are broken into smaller fragments, these fragments are
a fatty acid and amino acids
b amino acids and simple sugars
c amino acids and nucleotides
d fatty acids and glycerol

C. amino acids and nucleotides

Explanation:

When the viruses will be broken down, the constituent particles will be left behind.

Since the viruses are made up of the DNA and proteins, only amino acids and nucleotide fragments will be there this is because the DNA is made up of nucleotides and the proteins are made up of amino acids.

Hence , the correct option is C.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
