    What makes the pupil in the eye change size?

    • Experiement

    • Hypothesis

    • Question

    • Conclusion

    Correct Answer
    A. Question
    Explanation
    The pupil in the eye changes size in response to the amount of light entering the eye. When the amount of light is low, the pupil dilates (gets bigger) to allow more light to enter the eye and improve vision in dim conditions. Conversely, when the amount of light is high, the pupil constricts (gets smaller) to limit the amount of light entering the eye and prevent overexposure. This automatic adjustment of the pupil size is controlled by the iris muscles, which contract or relax in response to the brightness of the environment.

    What is the difference between a hypothesis and theory?

    • "Theory" is another word for "fact", hypothesis is another word for guess

    • Hypothesis can't be proven; theories can

    • Theories have been confirmed through tests; hypothesis haven't

    • Theories contain many hypotheses; a hypothesis only contains one theory

    Correct Answer
    A. Theories have been confirmed through tests; hypothesis haven't
    Explanation
    The answer states that theories have been confirmed through tests, while hypotheses have not. This means that a theory is supported by evidence and has been shown to be true or accurate, whereas a hypothesis is a proposed explanation or prediction that has not yet been tested or proven. The distinction lies in the level of evidence and confirmation that each concept possesses.

    If a recipe calls for 3 and 1/4 cups of flour, you can tell that it's using:

    • The customary system

    • The metric system

    • Both the customary system and the metric system

    • Neither the customary nor the metric system

    Correct Answer
    A. The customary system
    Explanation
    The correct answer is The customary system. In the customary system, measurements are typically expressed in cups, teaspoons, tablespoons, etc. The use of fractions, such as 1/4, is also common in this system. The metric system, on the other hand, uses units such as grams and liters, and does not typically use fractions in measurements. Since the recipe calls for 3 and 1/4 cups of flour, it is clear that it is using the customary system of measurement.
