Question

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

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.

Explanation:

Innate immunity does not produce antibodies for specific antigens. Adaptive immunity, on the other hand, can produce a higher amount of specific antibodies for the antigen, preventing the virus. Also, if the virus attacks again, the adaptive immunity (which has memory) can quickly respond. The skin is part of the innate immunity's physical barrier but it doesn't recognize antigens in the way described in some of the wrong options. Innate immunity doesn't give lifelong immunity in the way adaptive immunity (like from having an illness and the adaptive immune response) can in some cases (though for many viruses, it's the adaptive immunity's memory cells that help in quicker response on re - exposure, which can prevent or reduce illness severity).

Answer:

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