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?

Adrian's adaptive immunity remembered the antigens from the virus and gave him lifelong

immunity to it.

Adrian's innate immunity remembered the antigens from the virus and gave him lifelong immunity

to it.

Adrian's skin layer recognized the antigens and attacked them, which prevented the occurrence of

the virus again.

Adrian's innate immunity identified antibodies specific for the virus and targeted them against the

antigen.

Adrian's adaptive immunity produced a higher amount of specific antibodies for the antigen,

preventing the virus.

Walker Arroyo · Answer 1

The correct option is A) Adrian's adaptive immunity remembered the antigens from the virus and gave him lifelong immunity to it.

Explanation:

Whenever an infectious agent such as a virus infects our bodies, the memory cells of the adaptive immunity remember these infectious agents or antigens.

Next time, when the virus infects the body, the memory cells quickly recognize the antigen and antibodies are immediately produced to fight the antigen. As a result, the person does not get the infection next time as our immune system recognizes the antigen and quickly produce a response against it.
