General Science

  • Study of tissue is called:

    • Botany
    • Histology
    • Entomology
    • Zoology
    See Details

    Tissues are groups of cells that work together to perform specific functions in the body. Histology is the scientific study of tissues, including their structure, function, and composition. Histologists use microscopes and other tools to examine tissues at a microscopic level, which allows them to observe the cells and structures that make up the tissue.

  • The temperature at which water boils depends mainly on ____?

    • Air temperature
    • Relative humidity
    • Air pressure
    • Air density
    See Details

    The temperature at which water boils depends mainly on air pressure. As the atmospheric pressure decreases, the boiling point of water decreases as well, and vice versa. At sea level, water boils at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure, but at higher elevations where the atmospheric pressure is lower, the boiling point of water is lower.

  • What term is used when a plant is completely eliminated from the earth?

    • Endangered
    • Extinct
    • Native
    • Hybrid
    See Details

    The correct answer is Extinct. This term is used when a species, including plants, no longer exists on Earth. Extinction can be caused by natural factors such as climate change or human activities such as deforestation and pollution. Endangered refers to a species that is at risk of becoming extinct, while native refers to a plant or animal that naturally occurs in a particular region. Hybrid refers to a plant or animal that is the result of crossbreeding between two different species or varieties.

  • What is the normal blood pressure measured in millimeters of mercury (mmHg)?

    • 90/60 mmHg
    • 120/80 mmHg
    • 140/100 mmHg
    • 130/80 mmHg
    See Details

    The correct answer is 120/80 mmHg. This is considered the normal range for blood pressure in adults. Blood pressure is measured in millimeters of mercury (mmHg) and is expressed as two numbers: the top number (systolic pressure) measures the pressure in the arteries when the heart beats, while the bottom number (diastolic pressure) measures the pressure in the arteries when the heart is at rest between beats.

  • Bacteria is responsible for which of the following diseases:

    • Cough
    • Pneumonia
    • Rabies
    • Non of these

     

    See Details

    Pneumonia is an infection that inflames air sacs in one or both lungs, and it can be caused by various types of bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Legionella pneumophila, among others.
