Question

Quizplus · Accepted Answer

Both active and passive humoral immunity involve the use of antibodies. However, the difference between the two is that active immunity occurs when the body's own immune system produces antibodies in response to an antigen, while passive immunity involves the transfer of pre-made antibodies from another organism. Immunological memory is established by active immunization (such as vaccination), not passive immunization. Therefore, options A and B are incorrect. Option C is incorrect because active immunity does not involve acquiring antibodies from another organism.
