Question 6 options: A) cytotoxic T cells B) B cells C) T helper cells D) dendritic cellsnnate immunity: Question 1 options: A) is slower than adaptive immunity in responding to pathogens. B) is nonspecific and present at birth. C) involves a memory component. D) involves T cells and B cells.
- Which of the following is a characteristic of a cytotoxic T cell? Question 7 options: A) They originate in bone marrow. B) They have antibodies on their surfaces. C) They are responsible for the memory response. D) They recognize antigens associated with MHC I.Chlamydia is a bacterium with a capsule that hides its PAMPs. Therefore, Chlamydiacan Question 7 options: cause T cell autoimmunity. not stick to the host cells. promote antibody binding. enhance phagocyte digestion. avoid phagocyte binding.Give typed full explanation of both questions otherwise leave it question 2 last option : helper T cell receptiors and cytotoxic T cell receptors must bind the same antigen to active the cell mediated reaponse
- Question 2: Select one answer.One of the results of the inflammatory response is accumulation of fluid in the affected area (edema). This happens in response to tissue injury such as a sprained ankle or an infection caused by a splinter in one’s finger. Select the correct statement from the choices below. a. Activation of the inflammatory response does not indicate a disruption of homeostasis. Presence of extra fluid in the tissues directly activates the innate immune response. b.The lymph vessels will eventually drain away the excess fluid. The kinin-kallikrein system causes capillary leakage resulting in edema. c. The lymph vessels will bring in the cells from the immune system to fight any potential infection. d. Tissue edema does not involve the lymphatic system e.Swelling from tissue injury happens because your body makes excess fluid in that area.Select the best answer or answers from the choices given: The cell type most often invaded by HIV is a(n) (a) eosinophil, (b) cytotoxic T cell, (c) natural killer cell, (d) helper T cell, (e) B cell.Which statement about antibodies is INCORRECT? Question 16 options: Antibodies can be both soluble and membrane-bound. Antibodies bind to antigens via induced fit. Antibodies never release antigens once they are bound together. More than 100 million different antibodies can be produced in humans. Antibodies typically bind to antigens more strongly than enzymes bind to substrates.
