Question

Answer 1

d.humans
humans have the adaptive immune system that helps to prevent any pathogens from entering into the body or to destroy any pathogens that are entered inti the body. the adaptive immune system is carried out by white blood cells called lymphocytes. the lymphocytes have two different classes called B-cells and T-cells. B-cells secrete antibodies which are also called immunoglubulins. t-cells react directly against a foreign antigen that is entered into a host cell surface.
B-cells have receptors on their surface that can recognize different types of antigens. whenit comes in contact with an antigen it secretes antibodies that act against the antigens.
T-cells also have the receptors that detect foreign antigen. it attacks directly on the foreign antigen and eliminates the pathogen before it tries to replicate in the host cell.
