The enzymes that are used to replicate a virus are synthesized by the host cell. That is option A.
<h3>Process of viral infection.</h3>
A virus is a microorganism that has the ability to reproduce only by infecting a living host.
The main features of a virus include:
- nucleic acid genome ( RNA or DNA)
For a virus to be able to cause an infection,it has to pass through the following steps:
- Attachment of the virus to the host cell.
- Entry of the viral genetic material into the host cell
- Genome replication and gene expression: through the ribosomes of the host cells, enzymes are released which are used to replicate the invading virus to produce new ones.
Therefore, the enzymes that are used to replicate a virus are synthesized by the host cell.

Here is the answer on the attachment
Answer:
B
Explanation:
Darwin's theory is all about the Origins Of Species
The statement seen in B is not part of that theory due to it's irrelevance.
A. electrons move around the nucleus of an atom and can be exchanged between atoms
The overall equation of photosynthesis is:
6CO2 + 6H2O = C6H12O6 + 6O2
The overall equation for respiration is:
C6H12O6 + 6O2 = 6CO2 + 6H20 + Energy.
From these equations, it can be seen that the end products of photosynthesis are the starting products of the respiration process while the end products of the respiration process are the starting products of photosynthesis process.
