select all the correct answers. adrian caught a virus while staying with his grandmother. a few years later, his mother and sister got the same virus. this virus could spread through touch and direct contact. however, adrian did not contract the virus this time, even though he was living with his mother and sister. why did he not get sick? adrians adaptive immunity remembered the antigens from the virus and gave him lifelong immunity to it. adrians innate immunity remembered the antigens from the virus and gave him lifelong immunity to it. adrians skin layer recognized the antigens and attacked them, which prevented the occurrence of the virus again. adrians innate immunity identified antibodies specific for the virus and targeted them against the antigen. adrians adaptive immunity produced a higher amount of specific antibodies for the antigen, preventing the virus.

Answer

Brief Explanations:

Adaptive immunity has memory - it can remember antigens from previous infections and produce a stronger and faster response upon re - exposure. Innate immunity is non - specific and does not have memory. Skin is part of the innate immune system's physical barriers and does not recognize specific antigens in this way. Antibodies are produced by the adaptive immune system, not the innate immune system.

Answer:

A. Adrian's adaptive immunity remembered the antigens from the virus and gave him lifelong immunity to it. E. Adrian's adaptive immunity produced a higher amount of specific antibodies for the antigen, preventing the virus.
