The correct answer for the question that is being presented above is this one:
(1) viruses only: capsid, envelope with glycoproteins, capsomere (core protein)
<span>(2) host cell only: ribosome 
</span><span>(3) both: DNA, RNA, Protein</span>
        
             
        
        
        
In order to produce an effective immune response within the body, the person must be injected with a dosage of a virus or bacteria, and for it to be allowed to grow in the person, which replicates just enough to stimulate a response from the immune system.
