Label the diagram 2- A pathogenic bacterium has been engulfed by a phagocytic cell as part of the nonspecific (innate) immune response. Which of the following illustrations best represents the response? 3- An individual’s humoral response to a particular antigen differs depending on whether or not the individual has been previously exposed to that antigen. Which of the following graphs properly represents the humoral immune response when an individual is exposed to the same antigen more than once? a. b. c. d. e. f. What term describes the immune response labelled A on the graph? What term describes the immune response labelled B on the graph? Suggest what happened at the point labelled X on the graph Suggest what happened at the point labelled Y on the graph Describe the differences in response during A and B Explain the differences in response during A and B. a. How much antibody did each mouse have in its blood on day 5? b. Which mouse was already immune to the pathogen? Explain your answer. c. (i) On which day was Mouse A exposed to the pathogen again? (ii) Describe what happened to Mouse A’s immune system after it was exposed again. 1) In Figure, which letter on the graph indicates the patient's secondary response to a repeated exposure with the identical antigen? A) a B) b C) c D) d E) e 2) In Figure, which letter on the graph indicates the highest antibody peak during the patient's response to a second and distinct/different antigen? A) a B) b C) c D) d E) e 3) In Figure, the arrow at time (c) indicates A) the time of exposure to the same antigen as at time (a). B) the secondary response. C) the primary response. D) exposure to a new antigen. E) the T-cell response. 1) In Figure, what portion will typically attach to a host cell? A) a and c B) b C) b and c D) a and d E) e Which structure stimulate allergic response? Which parts considered involved in immune system? The diagram below shows an injury in which skin is pierced by a splinter. The flow diagram shows some of the events which result from this injury. The diagram below shows blood from a person who has been infected by bacteria. These bacteria have triggered an immune response involving proteins P and Q. a) Identify proteins P and Q. b) Cell R produced protein Q. Name this type of cell. A diagram of a stained blood smear observed under a light microscope is shown below. Which of the structures labelled A to D in the diagram is a phagocytic cell?
