Homework Answers
What is the name of the process where MHC molecules of an infected cell display antigens from a pathogen on their cell surface so T cells can identify and destroy the infected cell?
This process is called antigen processing and presentation.
Name three important properties of the acquired immune system-
It has memory due to which it can fight with pathogens.
It is specific.
It produces antibodies which are specific for a particular antigen.
Its secondary response is stronger than the primary response.
genetic process that allows B cells or T cells to produce specific antibodies?
This process is called class switching.

Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...

Describe the process by which a cell would display an intracellular (virus) on MHC, including how the pathogen gets in the cell and eventually gets placed on the correct MHC (tell me the class) and displayed on the cell surface.

1. Select the statements that correctly describe the role of the thymus, spleen, and lymph nodes in adaptive immunity. Select the TWO answers that are correct. The thymus is the site of T cell development. The thymus and lymph nodes work together in humoral immunity. The thymus and spleen produce B cells. Lymph nodes and the spleen filter pathogens from lymph and blood. The lymph nodes secrete lymphatic fluid. 2. How do humoral immunity and cell-mediated immunity differ? Select the...

QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on) is passed on to each generation, increasing the number of possible responses over time. Each lymphocyte is coated with many...
