Question 16 0.5 pts The school nurse is teaching a health class of eighth graders about infections and the antigen-antibody reaction. What is the best description that could be readily understood by 12 year old students? The antigen-antibody reaction is the binding of antigens to antibodies and is part of the immune response. This is an immune response in your body. The antigen causes your body to attach antibodies to kill the antigen. This is called the...
