    Which route of entry provides direct entry into the body, bypassing most of the body’s defenses?  

    • Absorption.

    • Inhalation.

    • Ingestion.

    • Injection.

    Correct Answer
    A. Injection.
    Explanation
    Injection provides direct entry into the body, bypassing most of the body's defenses. When a substance is injected, it is directly introduced into the bloodstream or tissues, allowing it to quickly reach its target and have a more immediate effect. This route of entry is often used for medical purposes, such as administering vaccinations or medications, as well as for illicit drug use. Unlike other routes of entry, such as absorption, inhalation, or ingestion, injection does not require the substance to pass through the digestive system or respiratory system, which can provide some level of protection or filtration.

    What is the effect of a chemical asphyxiant on the body?  

    • Inflammation of mucous membranes of the respiratory tract.

    • Destruction of tissue due to contact with material.

    • Reduction of the body’s capacity to use oxygen.

    • Depression of the central nervous system.

    Correct Answer
    A. Reduction of the body’s capacity to use oxygen.
    Explanation
    A chemical asphyxiant reduces the body's capacity to use oxygen. This means that the chemical interferes with the body's ability to transport and utilize oxygen, which is essential for normal bodily functions. This can lead to a decrease in oxygen levels in the body, resulting in various symptoms and potentially serious health consequences.

    Which of the following statements best describes an autotrophic organism?  

    • Use already formed organic compounds as a basis for food.

    • Can be further categorized as phagotrophs or saprotrophs.

    • Are classified by their type of respiration.

    • Manufacture their own food entirely.

    Correct Answer
    A. Manufacture their own food entirely.
    Explanation
    Autotrophic organisms are able to manufacture their own food entirely, meaning they can produce organic compounds through processes such as photosynthesis or chemosynthesis. They do not rely on already formed organic compounds as a basis for food, nor are they classified by their type of respiration. The statement about autotrophs being further categorized as phagotrophs or saprotrophs is incorrect, as these terms refer to different modes of obtaining nutrients, not different types of autotrophs.
