Homework Answers

Answer #1

9. option B is correct.

B cells are not destroyed in any case.

10. The statement is True.

anbodies contain two types of chain : heavy chain and light chain.

11. the given statement is true.

antibodies form complex with invader and disable it to bind with other cells. due to this invader dies itself.

12. The given statement is false.

memory cells are made from B-cells.

13. The given statement is true.

class switching is a biological mechanism that changes production of immunoglobins from one type to another.

14. The given statement is true.

HIV causes the death of CD4 T-cells.

15. The given statement is true.

our body immune system recongnise self and non self (foreign) cells.

Adaptive immunity has several features that distinguish it from innate immunity. Specificity in that each adaptive immune response is induced by a particular antigen, or surface feature that generates an antibody. An innate immune response might be stimulated by a PAMP, while an adaptive immune response is stimulated by a single feature of a bacteria. In addition, cells of adaptive immunity, B and T cells, are allowed to proliferate under certain conditions to mount a defense, this feature is clonality...

1. Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. The most important feature of a neutralizing antibody is: A. Having a high degree of multi-valency, such as being a pentamer or hexamer of immunoglobulin monomers B. Having high affinity for the antigen C. Being present at a high concentration in the circulation D. Being efficient at activating the complement...
