    Bacteria that cause disease are called:

    • A.

      Nonpathogenic

    • B.

      Protozoa

    • C.

      Pathogenic

    • D.

      Saprophytes

    Correct Answer
    C. Pathogenic
    Explanation
    The correct answer is pathogenic. Pathogenic bacteria are those that can cause diseases in humans, animals, or plants. They have the ability to invade and multiply within the host's body, leading to various illnesses and infections. These bacteria can produce toxins or damage tissues, resulting in symptoms and health complications. It is important to identify and treat pathogenic bacteria to prevent the spread of diseases and promote public health.

    Disease in plant or animal tissue is caused by:

    • A.

      Acidophilus

    • B.

      Saprophytes

    • C.

      Pathogenic bacteria

    • D.

      Nonpathogenic bacteria

    Correct Answer
    C. Pathogenic bacteria
    Explanation
    Pathogenic bacteria are capable of causing disease in plant or animal tissue. Unlike nonpathogenic bacteria, which do not cause harm, pathogenic bacteria have the ability to invade and multiply within the host organism, leading to the development of various diseases. This can occur through the production of toxins or by directly damaging the cells and tissues of the host. Acidophilus and saprophytes are not typically associated with causing disease, making pathogenic bacteria the most likely cause.

    The type of bacteria called cocci has a:

    • A.

      Spiral shape

    • B.

      Round shape

    • C.

      Rod shape

    • D.

      Corkscrew shape

    Correct Answer
    B. Round shape
    Explanation
    Cocci is a type of bacteria that is spherical or round in shape. This shape allows them to easily divide and reproduce, as they can divide in multiple planes. The round shape also helps them to resist external pressure and maintain their structural integrity. Additionally, this shape enables them to attach to surfaces and form colonies. Therefore, the correct answer is round shape.

      Staphylococci

    • C.

      Spirilla

    • D.

      Bacilli

    Correct Answer
    D. Bacilli
    Explanation
    Bacilli is the correct answer because it refers to a type of bacteria that has a rod shape. The term "bacilli" is derived from the Latin word "bacillus," meaning small rod. This shape distinguishes bacilli from other types of bacteria, such as diplococci (which are spherical), staphylococci (which are round clusters), and spirilla (which are spiral-shaped).

    Pus-forming bacteria that cause strep throat and blood poisoning are:

    • A.

      Streptococci

    • B.

      Bacilli

    • C.

      Staphylococci

    • D.

      Diplococci

    Correct Answer
    A. Streptococci
    Explanation
    Streptococci are pus-forming bacteria that are known to cause strep throat and blood poisoning. They are spherical in shape and often form chains or pairs. Streptococci are commonly found in the throat and can cause various infections, including strep throat, scarlet fever, and cellulitis. They are also responsible for more severe infections like necrotizing fasciitis and sepsis. Staphylococci, on the other hand, are another type of bacteria that can cause similar infections but are not specifically mentioned in the question. Bacilli and diplococci are different types of bacteria and are not associated with strep throat or blood poisoning.

    The bacteria with a corkscrew or spiral shape are:

    • A.

      Staphylococci

    • B.

      Spirilla

    • C.

      Diplococci

    • D.

      Bacilli

    Correct Answer
    B. Spirilla
    Explanation
    Spirilla are bacteria that have a corkscrew or spiral shape. They are characterized by their long, rigid bodies and can be found in various environments such as water and soil. Unlike staphylococci, which are spherical clusters, spirilla have a distinct spiral shape. Diplococci, on the other hand, are bacteria that exist as pairs of spherical cells, while bacilli are rod-shaped bacteria. Therefore, the correct answer for bacteria with a corkscrew or spiral shape is spirilla.

    Cocci rarely:

    • A.

      Show self-movement

    • B.

      Undergo mitosis

    • C.

      Reproduce

    • D.

      Are pathogenic

    Correct Answer
    A. Show self-movement
    Explanation
    Cocci rarely show self-movement because they are typically spherical in shape and lack the structures necessary for independent movement, such as flagella or cilia. Instead, they rely on external factors such as air or fluid currents to move.

    Certain bacteria, during their inactive stage, form outer coverings called:

    • A.

      Daughter cells

    • B.

      Flagella

    • C.

      Spores

    • D.

      Toxins

    Correct Answer
    C. Spores
    Explanation
    During their inactive stage, certain bacteria form outer coverings called spores. Spores are a protective mechanism that allows bacteria to survive unfavorable conditions such as extreme temperatures or lack of nutrients. These spores are highly resistant and can remain dormant for long periods until conditions become favorable again. Once conditions improve, the spores can germinate and give rise to active bacterial cells.

    A sign of bacterial infection is:

    • A.

      Pus

    • B.

      Bleeding

    • C.

      A cold

    • D.

      Parasites

    Correct Answer
    A. Pus
    Explanation
    Pus is a thick, yellowish fluid that is produced as a response to infection. It is composed of dead white blood cells, bacteria, and tissue debris. The presence of pus is a clear indication of a bacterial infection as it is the body's way of fighting off the infection and removing harmful substances. Bleeding, a cold, and parasites are not specific signs of a bacterial infection and can be caused by various other factors.

    Diseases caused by viruses include:

    • A.

      Measles and hepatitis

    • B.

      Abscesses and boils

    • C.

      Strep throat and blood poisoning

    • D.

      Tuberculosis and tetanus

    Correct Answer
    A. Measles and hepatitis
    Explanation
    Measles and hepatitis are both diseases caused by viruses. Measles is caused by the measles virus, which is highly contagious and primarily affects children. It is characterized by a rash, high fever, cough, and runny nose. Hepatitis, on the other hand, refers to inflammation of the liver and can be caused by different types of hepatitis viruses, such as hepatitis A, B, or C. Hepatitis can lead to liver damage and can be transmitted through contaminated food or water, blood transfusions, or sexual contact. Both measles and hepatitis are serious diseases that can have long-term health consequences if not properly treated.

    The disease that breaks down the body's immune system is known as:

    • A.

      Hepatitis

    • B.

      Pediculosis capitis

    • C.

      Tuberculosis

    • D.

      AIDS

    Correct Answer
    D. AIDS
    Explanation
    AIDS, or Acquired Immunodeficiency Syndrome, is a disease that weakens and breaks down the body's immune system. It is caused by the Human Immunodeficiency Virus (HIV), which attacks and destroys the CD4 cells, a type of white blood cell that helps the body fight off infections and diseases. As the immune system becomes compromised, individuals with AIDS are more susceptible to opportunistic infections and certain types of cancers. Therefore, AIDS is the correct answer for the disease that breaks down the body's immune system.

    Rate this question:

  • 14. 

    Acquired Immune Deficiency Syndrome (AIDS) is caused by:

    • A.

      The herpes virus

    • B.

      Contaminated food

    • C.

      Poor personal hygiene

    • D.

      The HIV virus

    Correct Answer
    D. The HIV virus
    Explanation
    Acquired Immune Deficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV). HIV weakens the immune system over time, making it difficult for the body to fight off infections and diseases. This eventually leads to the development of AIDS. The other options mentioned, such as the herpes virus, contaminated food, and poor personal hygiene, are not the direct cause of AIDS.

    Rate this question:

  • 15. 

    The HIV virus is not transmitted:

    • A.

      Through unprotected sexual contact

    • B.

      By kissing or hugging

    • C.

      Through cuts and sores

    • D.

      By IV users sharing needles

    Correct Answer
    B. By kissing or hugging
    Explanation
    HIV is not transmitted through kissing or hugging because the virus is not present in saliva or sweat. HIV is primarily transmitted through unprotected sexual contact, sharing needles among IV drug users, and contact with infected blood through cuts or sores. Kissing or hugging does not involve direct exchange of bodily fluids that could contain the virus, making it a safe form of physical contact.
