Question

Which kind of immunity is built up over time in response to specific antigens?

Answer 1

Answer:

Acquired immunity

Explanation:

Acquired immunity is a type of immunity that we develop when we get exposed to some antigens. Our immune systems can build a defense against those antigens and next time when we encounter those same antigens our body will know how to react. This immunity builds up over time in order to have an answer ready when a threat presents itself.
