Solution
Answer for question on top (number 31):
If you acquire an infection and get sick, that means you have been infected with a particular
pathogen. In response to it, your body produces antibodies (White Blood Cells) and some of the
WBCs remain in the body after infection subsides. If you become infected again with the same
pathogen, the WBCs that remained in your body, reproduce very rapidly and kills the pathogens.
This is ACTIVE IMMUNITY. So you can say that active immunity comes from exposure to
pathogens.
As this immnunity is not innate (i.e. inherited or based on genetic predisposition) but
ACQUIRED, also called as ADAPTIVE defense mechanism for fighting against infection, you
will have ACQUIRED IMMUNITY..
Thirdly, the antibodies are produced in your own body in this case (and not induced externally
through vaccination/immunization or antibodies transfer, this would be NATURAL
