A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old
STatiana [176]

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.

Misha Larkins [42]

Answer:

Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.

Explanation:

Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
