active immunity makes sure you don't have the virus again for example chicken pox if you have chicken pox once you have active immunity so you cannot get it again.


Explain why a virus might exist for years and only become active once it comes into contact with a living cell?

A virus can remain dormant for years because it is not a living organism and does not have the ability to replicate on its own. Once it comes into contact with a living cell, the virus can hijack the cell's machinery to replicate itself and cause an infection. The activation of the virus is triggered by specific signals or conditions present in the host cell.

Second step in the reproductive cycle of an active virus?

The second step in the reproductive cycle of an active virus is penetration and entry into the host cell. Once the virus attaches to the host cell surface, it enters the cell through various mechanisms such as endocytosis or direct fusion with the cell membrane. This step allows the virus to deliver its genetic material into the host cell where it can begin replication and assembly of new virus particles.
