an illness caused by a certain virus includes fever, rash, joint pain, red eyes, and headache. the virus is transmitted to people by infected mosquitoes. symptoms quickly occur within three to seven days after contracting the virus.
which description best explains the reproductive cycle of this virus?
○ lytic, because of the quick incubation time.
○ lysogenic, because the virus causes a fever.
○ lysogenic, because there is no way to acquire immunity against it.
○ lytic, because the virus is transmitted by mosquitoes.

Explanation:

The virus shows rapid symptom onset (within days after infection), which is characteristic of the lytic cycle—where viruses immediately replicate, lyse host cells, and cause quick, acute symptoms. The other options are incorrect: lysogenic cycles involve dormant viral integration with delayed symptoms, fever is not unique to lysogenic cycles, immunity can develop to lytic viruses, and transmission method does not define the reproductive cycle type.

Answer:

Lytic, because of the quick incubation time.
