What will be an ideal response?
(1 ) Specificity: The immune response is triggered by a specific antigen and defends against only that antigen. (2 ) Versatility: The immune system can differentiate among hundreds of millions of antigens that it might encounter during a normal lifetime. (3 ) Memory: The immune response following the second exposure to a particular antigen is stronger and lasts longer than before. (4 ) Tolerance: Some antigens, such as those on your own cells, do not elicit an immune response.
