This is not a homework. I found this exam question in my course at university. And I tried to search in my textbook and google but I can't find it. So I ask it here.

I think this is gap junction but the answer said it is tight junction

2.Destruction of stress fiber is most adversly effect?
A.Cell division B.Cell contraction C.Sperm movement D.Epithelium adhesion
stress fiber is related to A B D so I don't know

3.Which the following stem cell therapy is routinely used to treat disease in present?
A.Bone Marrow Stem Cell B.Mesenchymal Stem Cell C.Pherripheral blood stem cell
D.Umbilical cord blood stm cell E.Blastocyst Embryotic stem cell

May be D

4.Which disease shoukd not be treated by cell-based therapy?
A.HIV B.burns C.Diabetes Millitus D.Spinal cord injury E.Parkinson's and Alzhiemer Disease

I think it is A

5.The first thing that is used to counteract virus is?
A.Secertory IgA B.Interferon-alpha C.NK cell D.Natural antibody D.Polymorphonuclear cell

maybe nk cell

And why?

Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
