    True or False? Light travels in straight lines??

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Light travels in straight lines because it is a form of electromagnetic radiation that propagates through space as waves. These waves move in a straight line until they encounter an obstacle or are refracted or reflected by a medium. This behavior is explained by the principle of rectilinear propagation of light, which states that light travels in straight lines unless it interacts with another object or medium.

    • Water+Carbon Dioxide= Nitrogen+Oxygen

    • Glucose+Oxygen=Carbon Dioxide+Water

    • Glucose+Oxygen=Carbon Dioxide+Nitrogen

    Correct Answer
    A. Glucose+Oxygen=Carbon Dioxide+Water
    Explanation
    The word equation for respiration is glucose + oxygen = carbon dioxide + water. During respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. This process releases energy that is used by cells for various functions.
