Yes, it is possible to develop effective vaccines for any type of viruses. Genetically engineered viruses exhibit similar characteristics to natural viruses.
<h3>What is a virus?</h3>
A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).
A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.
Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.

Response would be correct, as in response to environment.
The answer would be D. The definition of a homologous structure is an organ or body part that appears in different animals and is similar in structure and location, but doesn't necessarily share the same purpose. The birds and rabbits have similar bones in their forelimbs, but one uses them to run and other uses them to fly.
