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.
