24 Viruses & Bacteria 1st Line of Defense
Standard 10A & 10D Viruses & Bacteria 1st Line of Defense

25 Antigens Amylase Lysozymes Lysosomes
19. (10a) ____ is an enzyme found on the skin, in the saliva and in tears that kills bacteria by breaking down their cell wall. Antigens Amylase Lysozymes Lysosomes

26 Production of antibodies Production of lysozymes
20. (10a) Which of the following is not a way that the skin acts as a nonspecific defense against disease? Production of sweat Forms an outer layer Production of antibodies Production of lysozymes

27 21. (10a) The body’s first line of defense against disease is ____?
Killer T Cells Antibodies The skin Interferon Roving macrophages

28 22. (10d) Unlike lytic viruses, lysogenic viruses do NOT
Injected their genetic material into the host cell. Enter the lytic cycle. Lyse the host cell right away. Infect host cells.

29 23. (10d) Antibiotics are used to treat infectious diseases caused by
fungi viruses bacteria Bacteria & viruses

30 24. (10d) Interferon is a natural chemical used primarily to fight ___ infections.
fungal viral bacterial Bacterial & viral

31 25. (10d) The cell structure below is a
Plant Cell Virus Animal Cell Bacteriophage Bacterial Cell

32 The Lines of Defense Against Viruses & Bacteria
Standard 10B & 10C The Lines of Defense Against Viruses & Bacteria

33 26. (10c) A vaccine contains _____
Antibodies Dying or weak viruses antibiotics Fully potent fungus tissue

34 27. (10b) Which of the following is the function of antibodies in the immune response?
Antibodies produce antibiotics. Antibodies attach to antigens and attract phagocytes which engulf & destroy the antigen. Antibodies produce interferon.

35 28. (10c) An infectious disease is one caused by
Heredity Materials in the environment Pathogens Hemophilia E

36 29. (10c) A person who has received a vaccine against polio
Is able to produce antibodies against polio. Has polio antibodies in the blood. Has antipolio killer T cells in blood. Is more susceptible to the polio virus than someone who has not had the vaccine.

37 HIV & The Immune Response
Standard 10E & 10F HIV & The Immune Response

38 30. (10f) Cells that are directly responsible for the production of antibodies are
Red Blood Cells Phagocytes T-cells B-cells

39 31. (10e) HIV weakens the immune system by killing
Antibodies B Cells Helper T Cells Killer T Cells

40 32. (10e) HIV spreads through the body by
Replicating inside the cells of the immune system. Preventing the body from producing antibodies against HIV. Causing the body to have asthma attacks. Strengthening the immune system.

41 33. (10e) Zidovudine (AZT) is a drug that stops an enzyme that HIV needs to multiply. What effect would you expect AZT to have on the number of T cells in an HIV-infected person’s blood and immune system? AZT should increase T cells. AZT should decrease T cells. AZT has no effect on T cells because it decreases plasma cells.

42 34. (10e) White blood cells that bind to infected cells and secrete chemicals that disrupt the cell membranes of these cells are termed Helper T-cells Killer T-cells Macrophages plasma Cells
