Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.

Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by <em>nuclear pore complex.</em> It allows the pore to <u>regulate the movement of molecules between the nucleus and the cytoplasm.</u> It allows small particles to pass through such as ribosomal proteins. It prevents most large particles<em> (except for histone)</em> from passing through; thus, <u>it is selective in nature</u>. This function of the pores clearly shows that <em>it allows communication to occur between the nucleus interior and the cytoplasm.</em>
