Which of the following is NOT a mechanism used by the immune system to fight multicellular parasites? Select one: a. Antibodies coating the pathogen surface bind to FcRs on mast cells, causing release of granule contents onto surface, and damage the parasite. b. Crosslinking of antibody binding to FceRI on eosinophils cells triggers release of granules, causing smooth muscle contractions. Muscle contractions in the mucosal tracts causes sneezing, coughing, vomiting or diarrhea, dislodging the parasite. d. The parasite is killed and broken down extracellularly, and then phagocytosed by macrophages. C.

Which of the following is not true about the complementsystem?(a) It is a set of more than 20 proteins that play a key rolein host defense by specifically acting in different waystoward different microorganisms.(b) Its general functions include enhancing phagocytosis byphagocytes, lysing microbes and enveloped viruses directly, and generating peptide fragments that regulateinflammation and immune responses.(c) It is a fast-acting innate host defense that works in a cascade.(d) There are three pathways classical, lectin, and alternative.(e) The effects of each activation pathways are the same.
Malaria disease is characterized by cycles of symptoms that last 4-8 hours and have 3 stages; a 15-to-60 minute cold stage when you shiver and feel very cold, a 2-6 hour hot stage when your fever may reach as high as 41oC and finally, a 2-4 hour sweating stage during which your fever drops rapidly. These cycles are called paroxysms. Explain why they typically happen in malaria patients based on the pathogen life cycle
Consider that the Herd Immunity Threshold is dependent on the reproduction number for an infectious disease. The combination of herd immunity and quarantines were highly effective for eradicating smallpox. What is different about the symptoms of polio infection that makes quarantining infected individuals much more difficult?

( select all the correct answers) Group of answer choices a) Attracting natural killer cells to destroy an infected cell. b) Blocking the ability of a pathogen to bind to a host cell c) Lysing a pathogen cell wall or lipid bilayer. d) Marking a pathogen so that innate immune cells destroy the pathogen. e) Helping complement proteins bind to a pathogen.
Which of the following statements is NOT true of a fever?a. Temperature is regulated by chemicals that reset the body's thermostat to a higher setting.b. The higher than normal body temperature impairs the functions of some bacteria.c. The higher than normal body temperature is always harmful.d. The higher temperature impairs leukocytes andantibody production.e. Both c and d. Which of the following statements is NOT true of antibodies?a. They bind to foreign antigens, making them susceptible to being engulfed by phagocytes.b. They serve as specific binding sites on B cells.c. An antibody is usually able to bind to a variety of different types of antigensd. They are composed of two heavy chains and two light chains.

Substances that are injected containing an antigen to stimulate the immune system to respond are called a- antibodies b- medications. c- vaccines d- antibiotics
Two scientists, Behring and Kitasato, injected tetanus toxin into rabbits, then collected serum from these animals. They then took 6 mice and injected .2ml of the collected serum into each of 6 mice. 24 hours later, they infected the 6 mice with tetanus bacteria. The 6 mice survived the infection. What type of immunity did the mice have? How long will the immunity last? Explain your answer to both questions.
