    What is the scientific terminology for a force or chemical that causes a reaction to take place or speed up the process? (Such as heat, water, or amino acids)

    • Enforcer

    • Producer

    • Reactor

    • Catalyst

    • Enhancer

    Correct Answer
    A. Catalyst
    Explanation
    A catalyst is a scientific terminology for a force or chemical that causes a reaction to take place or speeds up the process. It is not the reactant itself, but it lowers the activation energy required for the reaction to occur, thereby increasing the rate of the reaction. Catalysts are not consumed in the reaction and can be used repeatedly. They provide an alternative reaction pathway with a lower energy barrier, allowing the reaction to proceed more easily.

    Helium is well-known to make your voice's tone much higher. A less renowned gas called Sulfur Hexafluoride, does the opposite. Which property of these gases is the reason your voice is influenced this way?

    • Temperature

    • Volume

    • Combustibility

    • Density

    • General Reactivity

    Correct Answer
    A. Density
    Explanation
    Helium is 6 times lighter than air, therefor the sound waves generated in your vocal chambers pass through the gas much more quickly than normal air. This raises the frequency and subsequently the tone of the sound. The reverse can be achieved by inhaling Sulfur Hexafluoride, because it is 6 times denser than normal air. It slows down your sound waves, and the tone becomes much lower.

    The small intestine is comprised of 3 parts. An example of one is the _________.

    Correct Answer
    Duodenum
    Jejunum
    Ileum
    Explanation
    The small intestine is divided into three parts: the duodenum, jejunum, and ileum. These three parts work together to digest and absorb nutrients from the food we eat. The duodenum is the first part of the small intestine and receives partially digested food from the stomach. The jejunum is the middle part and is responsible for the majority of nutrient absorption. The ileum is the final part and absorbs any remaining nutrients, as well as bile salts and vitamin B12. Therefore, all three parts are examples of segments within the small intestine.
