    What process converts sugars into energy and involves breathing oxygen?

    • A.

      Carbon Cycle

    • B.

      Respiration

    • C.

      Transpiration

    • D.

      Photosynthesis

    Correct Answer
    B. Respiration
    Explanation
    Respiration is the process that converts sugars into energy and involves breathing oxygen. During respiration, glucose molecules are broken down in the presence of oxygen to produce ATP, which is the main source of energy for cells. This process occurs in the mitochondria of cells and is essential for the survival of living organisms. The other options, such as the carbon cycle, transpiration, and photosynthesis, are not directly involved in the conversion of sugars into energy through oxygen consumption.

    What is another name for the windpipe?

    • A.

      Alveoli

    • B.

      Lungs

    • C.

      Bladder

    • D.

      Trachea

    Correct Answer
    D. Trachea
    Explanation
    The windpipe is another name for the trachea. It is a tube-like structure that connects the throat to the lungs and allows air to pass in and out of the respiratory system. The trachea is lined with cilia and mucus-producing cells that help filter and moisten the air we breathe. It then branches into smaller tubes called bronchi, which further divide into bronchioles and eventually lead to the alveoli in the lungs, where oxygen is exchanged for carbon dioxide.
