    A disease is caused by what?  Check all that apply.

    • Virus

    • Bacteria

    • Parasite

    • Breathing

    Correct Answer(s)
    A. Virus
    A. Bacteria
    Explanation
    A disease can be caused by viruses and bacteria. Viruses are tiny infectious agents that invade living cells and use them to replicate, often causing various diseases. Bacteria are single-celled microorganisms that can also cause diseases by infecting different parts of the body. Parasites can also cause diseases, but they are not listed as an option in the given answers. Breathing, on the other hand, is a normal physiological process and is not a direct cause of diseases.

    Rate this question:

  • 3. 

    What is a parasite?  Choose the answer that best fits the definition of a parasite.

    • A dead organism that survives off another organism.

    • A bug that flies around to different communities.

    • An organism that survives off another organism

    • An organism that lives with another organism

    Correct Answer
    A. An organism that survives off another organism
    Explanation
    A parasite is an organism that survives off another organism. This means that it relies on the host organism for its survival, often at the expense of the host's well-being. Parasites can be found in various forms, such as fleas, ticks, and tapeworms, and they obtain nutrients and resources from the host organism to sustain themselves. They may cause harm or disease to the host, but they themselves benefit from this relationship.

    • A dead organism that survives off another organism.

    • A bug that flies around to different communities.

    • An organism that survives off another organism

    • An organism that lives with another organism

    Correct Answer
    A. An organism that survives off another organism
    Explanation
    A parasite is an organism that survives off another organism. It relies on the host organism for its nourishment and may harm or weaken the host in the process. This relationship is often one-sided, with the parasite benefiting at the expense of the host. Parasites can be found in various forms, such as fleas, ticks, and tapeworms, and they can affect a wide range of organisms, including animals, plants, and even humans.

    Rate this question:

  • 7. 

    An internal parasite lives outside of its host.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    An internal parasite actually lives inside its host, not outside. It relies on the host for survival and obtains nutrients from it. Therefore, the correct answer is False.

    Rate this question:

  • 8. 

    Which of the following is a disease?

    • Tapeworms

    • Polyarthritis

    • Ticks

    • Ascarids

    Correct Answer
    A. Polyarthritis
    Explanation
    Polyarthritis is a disease characterized by inflammation in multiple joints. It is a condition that affects the joints, causing pain, swelling, and stiffness. Tapeworms, ticks, and ascarids, on the other hand, are not diseases but rather different types of parasites. Tapeworms are flatworms that live in the intestines of animals, ticks are external parasites that feed on the blood of animals, and ascarids are roundworms that infect the intestines of animals. Therefore, the correct answer is Polyarthritis as it is the only option that represents a disease.
