        Warm air __________________________ - ProProfs

        Warm air __________________________

    • Rises

    • Falls

    Correct Answer
    A. Rises
    Explanation
    Warm air rises because it is less dense than cold air. When air is heated, its molecules gain energy and move faster, causing them to spread out. This increased spacing between the molecules makes the warm air less dense than the surrounding cooler air. As a result, the warm air is buoyant and tends to rise above the denser, colder air. This process is known as convection and is responsible for the formation of many weather phenomena such as thunderstorms and wind currents.

    What is a tsunami? Anatomy Tsunamis are barely noticeable in the open ocean.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Tsunamis are indeed barely noticeable in the open ocean. This is because they are characterized by long wavelengths and low wave heights, making them difficult to detect. It is only when these waves approach shallow waters near the coast that they can grow in height and become destructive. Therefore, in the vast expanse of the open ocean, tsunamis can go unnoticed and pose little threat.

    Do all antibodies destroy all bacteria?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    Antibodies are proteins produced by the immune system in response to the presence of specific antigens, such as bacteria. However, not all antibodies are capable of destroying all bacteria. Antibodies work by binding to specific antigens on the surface of bacteria, marking them for destruction by other immune cells or neutralizing their harmful effects. The specificity of antibodies allows them to recognize and target only certain bacteria, while others may require different antibodies or immune responses for their elimination. Therefore, not all antibodies can destroy all bacteria.
