-memory cells

Accepted Answer

Memory cells are lymphocytes that remain in the body after an initial immune response, ready to respond more rapidly and effectively to subsequent encounters with the same antigen.

Question 2

Classification.Respond to the following statements with reference to the five types of white cells listed below.
a.macrophages
b.helper T cells
c.B cells
d.cytotoxic T cells
e.natural killer cells
-Antibody production occurs in these cells.

Accepted Answer

Antibody production primarily occurs in B cells, which are responsible for recognizing foreign antigens and activating the production of antibodies. While other white blood cells such as helper T cells and macrophages contribute to the immune response, they do not directly produce antibodies. Cytotoxic T cells and natural killer cells primarily function in destroying infected or cancerous cells, rather than producing antibodies.

Accepted Answer

Antibodies are proteins produced by effector B cells that bind specifically to foreign proteins, such as antigens.

Answer: A
 Antigens are foreign proteins that trigger an immune response, including the production of antibodies by effector B cells, and the activation of helper T cells and cytotoxic T cells.

Answer: C
 Helper T cells are a type of immune cell that recognize foreign proteins (antigens) and help activate other immune cells, including B cells and cytotoxic T cells.

Answer: D
 Cytotoxic T cells are a type of immune cell that kill infected or cancerous cells by recognizing and binding to specific foreign proteins (antigens).

Accepted Answer

Retroviruses are a group of RNA viruses that use a reverse transcriptase enzyme to produce DNA from their RNA genome, which then integrates into the host cell's genome. One retrovirus, HIV, has been identified as the causative agent of AIDS.

Answer: M
 A preparation injected into the body to elicit a primary immune response is called a vaccine. Vaccines contain either weakened or dead pathogens, parts of pathogens, or synthetic molecules that resemble a pathogen's surface patterns, which stimulate the immune system to produce a response without causing disease.
