Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The simulation from class does not represent how long the actual immune response takes because ____
A
the actual immune response can take a lot longer (days, weeks, months)
B
the actual immune response happens much faster
C
This is false ____ the simulation DOES represent how long the actual immune response takes
D
None of the above
Explanation: 

Detailed explanation-1: -The adaptive (active) immune response takes 1 to 2 weeks to reach its full functioning capacity, much longer compared to the twelve hours required to activate the innate immunity completely.

Detailed explanation-2: -The adaptive, or acquired, immune response takes days or even weeks to become established-much longer than the innate response; however, adaptive immunity is more specific to an invading pathogen. This part of the immune system works in tandem with the innate immune response to neutralize pathogens.

Detailed explanation-3: -Whereas in a primary encounter, antibodies are not generated for several days, during a memory response antibodies appear in just a few days.

Detailed explanation-4: -The reaction can be divided into two stages – 1) Immediate, in which release of preformed mediators cause the immune response, and 2) Late-phase response 8-12 hours later, in which the cytokines released in the immediate stage stimulate basophils, eosinophils, and neutrophils even though the allergen is removed.
