    Fill in the blank.  Antibodies are made by __-Cells (its a letter)

    Correct Answer
    B, b
    Explanation
    Antibodies are made by B-cells, which are a type of white blood cell. B-cells are responsible for producing antibodies in response to foreign substances, such as bacteria or viruses, that enter the body. These antibodies help to identify and neutralize these foreign substances, playing a crucial role in the immune response. The lowercase 'b' is used to represent B-cells in this context.

    Rate this question:

  • 8. 

    Antibodies are produced by specialized white blood cells called T cells.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Antibodies are produced by specialized white blood cells called B cells, not T cells. B cells are responsible for humoral immunity, which involves the production of antibodies that circulate in the blood and lymph, targeting specific pathogens. T cells, on the other hand, are involved in cell-mediated immunity, directly attacking infected cells or coordinating the immune response.

    True or false? Aging has no effect on the immune system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Aging does have an effect on the immune system. As people age, their immune system becomes less efficient and effective in fighting off infections and diseases. This is due to a decrease in the production of immune cells and a decline in their function. Additionally, aging can also lead to chronic inflammation, which negatively impacts the immune system. Therefore, it is incorrect to say that aging has no effect on the immune system.

    Multiple Choice. What is the major function of the B-Cells?

    • Produce Antibodies

    • To kill viruses

    • To kill people

    Correct Answer
    A. Produce Antibodies
    Explanation
    B-cells are a type of white blood cell that play a crucial role in the immune response. Their major function is to produce antibodies, which are proteins that help to identify and neutralize foreign substances such as bacteria and viruses. Antibodies bind to these foreign substances, marking them for destruction by other immune cells or by activating the complement system. This immune response is essential for preventing and fighting infections. Therefore, the major function of B-cells is to produce antibodies.

    • Thymus

    • Spleen

    • All of the above are a part of the immune system

    Correct Answer
    A. All of the above are a part of the immune system
    Explanation
    The correct answer is "All of the above are a part of the immune system" because bone marrow, thymus, and spleen are all organs that play a role in the immune system. Bone marrow produces immune cells, thymus is involved in the development of T cells, and spleen filters the blood and helps in the removal of old or damaged red blood cells. Therefore, none of these organs can be considered as not a part of the immune system.

    Multiple Choice.  _______ is what your body produces when your having a allergic reaction.

    • Adrenaline

    • Histamine

    • Insulin

    • None of the above

    Correct Answer
    A. Histamine
    Explanation
    Histamine is what your body produces when you're having an allergic reaction. Histamine is released by the immune system in response to an allergen, such as pollen or certain foods. It causes symptoms like itching, sneezing, and swelling in an attempt to protect the body from the perceived threat. Antihistamines are commonly used to block the effects of histamine and alleviate allergic symptoms. Adrenaline, insulin, and none of the above are not produced during an allergic reaction.

    True or False? The second time your body comes across a foreign substance you will have a more intense response than the first time.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When the body encounters a foreign substance for the first time, it takes time to recognize and mount an immune response against it. However, during this initial encounter, the immune system creates memory cells that "remember" the foreign substance. So, when the body encounters the same substance for the second time, the immune response is quicker and more intense due to the presence of memory cells. This heightened response is known as an immune memory and is the basis for vaccinations and immune protection against future infections. Therefore, the statement "The second time your body comes across a foreign substance you will have a more intense response than the first time" is true.

    True or False. HIV is the only the only kind of VIRUS that is known to attack the human immune system directly and destroy T cells.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    HIV, or the Human Immunodeficiency Virus, is indeed the only known virus that directly attacks the human immune system and specifically targets T cells. T cells are a type of white blood cell that play a crucial role in the immune response. HIV infects and replicates within T cells, gradually weakening the immune system and making individuals more susceptible to infections and diseases. This is why HIV is considered a particularly dangerous virus and why it can lead to the development of AIDS (Acquired Immunodeficiency Syndrome) if left untreated.

    • Bone Marrow

    • Spleen

    • Lymph Nodes

    • Heart

    • Lungs

    • Leg

    • Foot

    • Arm

    Correct Answer(s)
    A. Bone Marrow
    A. Spleen
    A. Lymph Nodes
    Explanation
    The correct answer is Bone Marrow, Spleen, and Lymph Nodes. These organs are part of the immune system and play crucial roles in the body's defense against infections and diseases. The bone marrow is responsible for producing white blood cells, which are essential for immune responses. The spleen filters the blood and helps remove old or damaged red blood cells and pathogens. Lymph nodes are small bean-shaped structures that contain immune cells and help filter lymph fluid, trapping and destroying pathogens. The heart, lungs, legs, feet, and arms are not directly involved in the immune system.

    Fill in the blank. A chemical that kills bacteria or slows their growth without harming body cells is a ____________.

    Correct Answer(s)
    Antibiotic, Anti-biotic, Anti biotic
    Explanation
    An antibiotic is a chemical that can either kill bacteria or inhibit their growth without causing harm to the body's own cells. It is used to treat bacterial infections and is effective in targeting specific types of bacteria. The term "antibiotic" is derived from the Greek words "anti" meaning against and "bios" meaning life, indicating its ability to combat bacterial life. The variations in spelling (antibiotic, anti-biotic, anti biotic) all refer to the same concept and can be used interchangeably.
