Question

Why might knowledge of the gene and protein sequences of a species be useful in classifying that species? I think it is C bt im not sure ;/

a)It would allow more accurate naming of the species by basing names on genes rather than appearance.
b)It would keep the species from being interbred with any other species that might appear physically similar to it.
c)It would make it possible to compare that species to other species at a level deeper than outward appearance
d)It would prove that all the members of a given species were genetically identical to each other.

Answer 1

You are right its c)It would make it possible to compare that species to other species at a level deeper than outward appearance.

Answer 2

Why might knowledge of the gene and protein sequences of a species be useful in classifying that species?

c)It would make it possible to compare that species to other species at a level deeper than outward appearance

The proteins like hemoglobin and enzymes can be studied to see whether organism which are similar in form can also be related to each other. Its differences found in these proteins' amino acid sequences will present how closely or distantly related an organism is to another.
