Which statement about a secondary immune response is FALSE?
A) It is a response to an antigen.
B) It may occur years after a primary response.
C) It involves memory cells.
D) It has a longer latent period than a primary response.
E) It is stimulated by less antigen than a primary response.
Secondary Immune Response
The enhanced immune response elicited upon a second or subsequent exposure to a specific antigen, providing quicker and more effective protection.
Memory Cells
Long-lived immune cells that "remember" past infections, allowing for a faster and stronger response upon re-exposure to the same pathogen.
Latent Period
The time interval between exposure to a pathogen or initiating event and the onset of symptoms or disease.

Final Answer :
D
Explanation :
The secondary immune response has a shorter latent period than the primary response, meaning it activates more quickly due to the presence of memory cells created during the primary response.
