Question

During a humoral immune response, which of the following happens when a pathogen is recognized?

A) Memory B cells divide to form plasma cells that surround the pathogen.

B) The antibodies on B cells bind to the antigens on the pathogen’s surface.

C) Memory T cells produce helper T cells that search for the pathogen and destroy it.

D) Helper T cells signal cytotoxic T cells to attack cells infected by the pathogen.

Any help is appreciated! This is a pretest so please give a good explanation!

Non-specific chemical defenses

The non-specific chemical defenses in the human body can be seen in relation to most ‘inlets’ and ‘outlets’ of the body. For instance, the saliva and the tears would contain the enzyme ‘lysozyme’ and this has the ability to break the bacterial cell wall and thereby destroy the pathogenic bacteria trying to invade the human body.
