Which of the following indicates that the immune system has achieved versatility?
A) Millions of NK cells are produced to ensure efficient immune surveillance.
B) Lymphocytes, which are sensitive to an antigen, undergo repeated cell divisions.
C) Production of many normal B cells and T cells, which will attack "self" antigens, occurs.
D) Lymphocyte cell divisions produce two cell types: one group, which will attack specific antigens, and another group, which will remain inactive until exposed to the same antigen later.
E) Millions of different lymphocyte populations are produced, each with different antigen receptors.

Question

Quizplus · Accepted Answer

The production of millions of different lymphocyte populations, each with different antigen receptors, indicates that the immune system has achieved versatility. This allows the immune system to recognize and respond to a wide variety of antigens, including those that have never been encountered before. Options A, B, C, and D describe specific aspects of lymphocyte development and function, but do not indicate the same level of versatility as the production of millions of different lymphocyte populations.
