Question

What happens when an antigen is introduced into an organism?

Answer 1

Answer:

B. Monoclonal antibodies are produced from plasma cells

Explanation:

An antigen is a molecule present on the surface of a pathogenic organism and they are capable of generating an immune response by binding to specific antibodies (immunoglobulins) that are secreted by lymphocytes B cells of the immune system. B cells are a type of white blood cell that plays key roles during humoral immunity of the adaptive immune system. When an antigen is introduced into the organism, a specific lineage of B cells proliferate, in a process known as monoclonal expansion.
