Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence. I. Pathogen
is destroyed. II. Lymphocytes secrete antibodies. III. Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. IV. Lymphocytes specific to antigenic determinants from pathogen become numerous. V. Only memory cells remain.
The first response would be binding of antigenic determinants from pathogen to the receptors on lymphocytes then lymphocytes would become active and they increase their quantity followed by secreting antibodies that will eventually destroy the pathogen. Memory cells will recognize this pathogen as foreign body and they will always remember it.
