Answer:

destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophage

Explanation:

A cell-mediated immune response is an immune response that does not involve antibodies. Cell-mediated immune responses involve the destruction of infected cells by cytotoxic T cells, or the destruction of pathogens by macrophages.

The answer cannot be either of the options involving B cells, as these are involved in the antibody response. The cytotoxic T cells are what actually destroy the infected cells (not helper T cells).

hjlf

Answer:

If the inability of Tom to move his arms and legs has no apparent physical reason, it is likely that Tom may be suffering from conversion disorder.

Explanation:

Conversion disorders have a psychological basis, and they are dissociative disorders where there is a functional disturbance for no apparent reason. The term conversion means that a psychological problem can become a physical manifestation.

Tom is not able to move his arms and legs, but there is no medical reason why. Because of the trauma of losing his wife in an accident, it is possible that the cause of his paralysis is psychological, due to a conversion disorder secondary to a depressive disorder.
