Verified
During a specific defense, the process of increasing the numbers of the selected cells is called:
A) mitotic expansion.
B) clonal selection.
C) divisional activation.
D) lymphocytic activation.
E) memory establishment.
Clonal Selection
Lymphocyte activation in which a specific antigen causes activation, cell division, and differentiation only in cells that express receptors with
Mitotic Expansion
The increase in cell number through the process of mitosis, where a single cell divides to form two genetically identical daughter cells.
Memory Establishment
The process by which experiences are encoded and stored in the brain for later retrieval.
- Recognize the functions and diversification mechanisms of T and B lymphocytes within the immune system.
- Acquire knowledge on the distinctions between primary and secondary immune defenses, as well as the role of memory cells.

Final Answer :
B
Explanation :
Clonal selection is the process by which cells specific to a certain antigen proliferate to fight off the antigen, effectively increasing their numbers during an immune response.
