    Question: What term describes the ability of an organism to cause disease in other organisms (plants, animals, microorganisms)?

    Options:

    Virulence
    Pathogenicity
    Antibiosis
    None of the above

    -✅Explanation: Pathogenicity refers to the ability of an organism to cause disease in a host. This involves factors like virulence (severity of disease) and transmission mechanisms.

    📌Other Options Explanations:
    -(a) Virulence: Virulence refers to the degree of severity or harm caused by a pathogen in a host.
    -(c) Antibiosis: Antibiosis is the antagonism between microorganisms where one organism produces substances that inhibit the growth or survival of another.

    🔑Key Points: :
    -A pathogen, often known as an infectious agent, is a biological entity that afflicts its host with disease or illness.
    -Agents that interfere with an animal's or plant's normal physiology are most frequently referred to by this phrase.
    -Bacteria, viruses, and other microbes that can cause disease are all examples of pathogens.
    -The biological pathogen, such as a virus, parasite, fungus, or bacteria, that causes a disease is typically referred to as the disease-causative agent.
