The capsid is the protein shell that surrounds the core of a virus where its nucleic acid is located. The capsid is made up small sub units called capsomeres.
A virus consists of a nucleic acid which may either be RNA or DNA and is found in varying quantities in the virus. It is this nucleic acid that is vital to the virus' survival that is housed in the capsid.
A drug that targets the capsid and damages it will cause the nucleic acid to leak out of the virus and into the surrounding while other fluids foreign to the virus will get in rendering the virus totally impaired, and due to this the virus cannot survive but will speedily die.
I believe that the answer is D. If something has evolved, it can not interbreed with its old species. I think this is right!

Answer:
C. All fossils contain intact DNA that can be sequenced.
Explanation:
Fossils are the impression, trace or preserved remains of once-living thing from past thousands of years such as bones, exoskeletons, objects preserved in amber, and stone imprints of animals or microbes.
Fossils provide evidence about seevral characteristics and features of extinct organism such as evolutionary relationship between organisms and transitional forms between groups of organisms. but all the fossil do not provide evidence about the intact DNA that can be sequenced because some fossils carry DNA rumnants which do not have the ability to get sequenced.
Hence, the correct option is C.
People eat frogs and not trouts because if they eat trouts they would need one each day or 365 for the year.
