The clonal selection model states that Blank______.Multiple choice question.antigens bind to specific receptors on a B cell or a T cell, which then divides producing many identical copies of itselfantigens induce cells to undergo apoptosis, programmed cell deathantigen presenting cells display fragments of engulfed pathogens in the grooves of their MHC moleculesforeign cells will burst when complement proteins form a membrane attack complex in the target cell

Which of the following is true regarding clonal selection theory?Cassidy RhodyID: 112703Question 69Select one:Monocytes are constantly sampling the environment for antigensLymphocytes are constantly sampling the environment for antigensCells that recognize and bind strongly to self cells are positively selectedCells that recognize and bind to non-self antigens are positively selected

When a B cell or T cell is stimulated by antigen, it divides, producing many identical copies of itself. This is an important part of the selection model.

Which class of antibodies plays a role in activating the complement and clumping cells?Multiple ChoiceIgMIgGIgAIgDIgE

If a viral antigen were to bind to the receptors on the surface of a B lymphocyte, which of the following immune responses would NOT occur?A.Division of the B lymphocyte into cells that differentiate to secrete antibodiesB.Interaction of the B lymphocyte with other immune cells that stimulate B lymphocyte proliferationC.Secretion of toxins by the B lymphocyte that destroy nearby virus-infected cellsD.Proliferation of cells that can recognize the antigen more rapidly in the event of a future infection
