Quizplus · Accepted Answer

The statement "Fast-acting initial response mediated by complement" is not a defining characteristic of adaptive immunity. Complement is a component of the innate immune system, which provides the first line of defense against pathogens. Adaptive immunity, on the other hand, is characterized by its specificity and ability to tailor a response to a particular pathogen.
