    There are approximately 10,000 taste buds on the human tongue. Taste buds are small sensory organs that detect different tastes such as sweet, sour, salty, and bitter. They are located on the papillae, which are small bumps on the tongue's surface. These taste buds contain taste receptor cells that send signals to the brain when they come into contact with food or drink, allowing us to perceive and differentiate flavors.

    How fast is a sneeze?

    • 1 mph

    • 10 mph

    • 60 mph

    • 100 mph

    Correct Answer
    A. 100 mph
    Explanation
    A sneeze can travel at a speed of 100 mph. When a person sneezes, air is forcefully expelled from their nose and mouth. This force can propel the droplets containing the sneeze at a high velocity. Studies have shown that sneezes can travel up to 100 mph, which is comparable to the speed of a car on the highway. This high speed is why it is important to cover your mouth and nose when sneezing to prevent the spread of germs and droplets to others.

    How do your eyes change as you get older

    • Your pupils get larger

    • Your pupils get smaller

    • Your whites get whiter

    • Your whites get grayer

    Correct Answer
    A. Your pupils get smaller
    Explanation
    As you get older, your eyes undergo various changes. One of these changes is that your pupils tend to get smaller. This is due to the natural aging process and the loss of elasticity in the muscles that control the size of the pupil. Smaller pupils allow less light to enter the eye, which can result in decreased visual acuity, especially in low-light conditions.
