Which of the following cells can differentiate into plasma cells, which secrete antibodies, or become memory cells? (1 POINTS)
a. Antigen presenting cells
d. macrophages
c. B-cells
b. T-cells
c. B cells
B cells may differentiate into memory B cells or plasma cells. Most of these B cells will become or immature plasma cells and begin producing large volumes of antibodies.

O reticular cells macrophages O dendritic cells Tlymphocytes OB lymphocytes QUESTION 42 The layers of the adrenal cortex, in order from most superficial to deepest are: cortex, medulla zona glomerulosa, zona fasciculata, zona reticularis zona reticularis, zona fasciculata, zona glomerulosa Omedulla, zona glomerulosa zona medulla, zona cortica, zona fasciculata QUESTION 43 Which of the following statements is true? individuals with type AB blood have type A agglutinogens and anti-B agglutinins...
17. One distinction between B cells and T cells is that A. B cells directly attack an invader while T cells secrete antibodies that attack the invader B. T cells produce antibodies C T cells directly attack an invader while B cells become plasma cells that secrete antibodies that attack the invader D. both cell types attack invaders directly but some B cells differentiate into plasma cells that also simultaneously secrete antibodies
Question 4 1 pt Which of the following is true of B cells (select ALL that apply): born in the bone marrow O can differentiate into plasma cells some types can directly kill a target cell mature in the bone marrow born in the thymus mature in the thymus make antibodies can differentiate into memory cells are considered "antigen-presenting" cells Question 5 1 pts B cell activation requires (select ALL that apply): antiren binding to antibody on B cell surface
Helper T cells: Multiple Choice o secrete perforin when activated. o convert to plasma cells after they are activated. o secrete antibodies that target specific antigens. o do not interact with MHC proteins. o O are activated by antigen presented with MHC Il proteins
Put the following steps in the process of B-cell activation in cause-and-effect order: Long-lived memory cells remain in the body to respond rapidly if the same antigen appears again The plasma cells produce and secrete large numbers of antibodies A helper T-cell with a complementary T-cell receptor binds the presented antigen The antigen is processed and presented by a class 2 MHC protein The T-cell releases cytokines that activate the B-cell An antigen binds to the B-cell receptors in the...
Question 1: B cells secrete these types of immunoglobulin antibodies. Choose all correct. 1. IgD 2. IgL 3. IgG 4. IgM 5. IgA 6. IgE True or False Questions 2. T cells expressing CD8 protein on their surface are called cytotoxic T cells and function in the killing the infected APC cell. 3. Antigen presentation on the cell surface is a way to tell the immune system that they are infected and the presented molecule tells T cells what they...
antibodies A specific B cell is activated when an) from a pathogen binds to one of the _ on its surface. Activation also requires from helper T cells. 1 antigen antigen This activated cell then begins dividing into memory B cells, which will participate in the secondary immune response, and cells that will act as protein factories in this immune response. plasma During the primary immune response, these cells secrete cytokines During the secondary immune response, the rapidly, giving rise...
A) lymph follicles lymph nodes C) lacteals D) lymphatics 4) An advantage to adaptive immunity is (A) its memory cells that provide quicker, larger and more efficient immune response upon second and subsequent exposure to an antigen B) its need for several cells to be activated over several days on first exposure C) the ability of its individual cells to respond to many different pathogens D) the use of antibodies that cause cell lysis and kill invading cells 5) A...
Which of the following activates cytotoxic T cells as part of the acquired immune response against virus infected cells? -Virus infected cell -Virus infected cell that presents a viral antigen on its surface -A virale infected cell that presents both a viral antigen and a MHC class 1 protein -A virale infected cell that presents both a viral antigen and a MHC class II protein Which of the following is a role of macrophages in a secondary lymph organ in...
