    True or False: the two types of immunization exemptions are medical and administrative.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the two types of immunization exemptions are indeed medical and administrative. Medical exemptions are granted when a person has a medical condition that prevents them from receiving certain vaccines. Administrative exemptions, on the other hand, are granted for non-medical reasons, such as religious or philosophical beliefs. Both types of exemptions allow individuals to be exempt from the usual immunization requirements.

    Once a T-Cell becomes excited and multiplies, it goes through a process called _______. This process produces new cells that are exact copies of the original cell

    • Phagocytosis

    • Clonal expansion

    • Complement system

    Correct Answer
    A. Clonal expansion
    Explanation
    Clonal expansion is the correct answer because once a T-Cell becomes excited and multiplies, it goes through a process called clonal expansion. This process involves the rapid proliferation of the T-Cell, resulting in the production of new cells that are exact copies of the original cell. These new cells play a crucial role in the immune response by recognizing and attacking specific antigens. Phagocytosis is the process by which cells engulf and digest foreign particles, while the complement system is a group of proteins that work together to enhance the immune response.

    Rate this question:

  • 13. 

    Which type of T-Cells kill abnormal host cells?

    • Helper t-cells

    • Regulatory t-cells

    • Killer or cytotoxic t-cells 

    Correct Answer
    A. Killer or cytotoxic t-cells 
    Explanation
    Killer or cytotoxic T-cells are a type of T-cells that are responsible for killing abnormal host cells. These cells play a crucial role in immune responses by identifying and destroying cells that have been infected with viruses or have become cancerous. They do this by releasing toxic substances that induce cell death in the target cells. Killer or cytotoxic T-cells are an essential component of the immune system's defense against infections and tumors.

    Rate this question:

  • 14. 

    Which immune system is our body's first line of defense against infection?

    • Innate or nonspecific

    • Adaptive or specific

    Correct Answer
    A. Innate or nonspecific
    Explanation
    The innate or nonspecific immune system is our body's first line of defense against infection. It is called nonspecific because it provides a general defense mechanism against a wide range of pathogens, without targeting specific antigens. This immune system includes physical barriers like the skin and mucous membranes, as well as cellular components like phagocytes and natural killer cells. These components work together to quickly recognize and eliminate foreign invaders, providing immediate protection against infections. The adaptive or specific immune system, on the other hand, is a more targeted response that develops over time and specifically targets antigens that have been encountered before.

    These lymphocytes mature in the thymus and are responsible for cell-mediated immunity

    • T-lymphocytes

    • B-lymphocytes

    • T-cells

    • Histamines

    Correct Answer
    A. T-lymphocytes
    Explanation
    T-lymphocytes, also known as T-cells, are a type of lymphocyte that mature in the thymus. They play a crucial role in cell-mediated immunity, which involves the activation of immune cells to directly attack and destroy infected or cancerous cells. T-lymphocytes recognize specific antigens on the surface of these abnormal cells and initiate an immune response to eliminate them. This response can include the release of chemicals called cytokines, which attract other immune cells to the site of infection or inflammation. Therefore, T-lymphocytes are responsible for coordinating and regulating the body's immune response against pathogens and abnormal cells.
