  • 2. 

    If pollen is passed from flower to flower, pollination occurs.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When pollen is transferred from one flower to another, it results in pollination. This process is essential for the reproduction of flowering plants, as it allows the transfer of male gametes (contained in the pollen) to the female reproductive organs of the flowers. This transfer can occur through various means, such as wind, water, or the activity of animals like bees or butterflies. Therefore, the statement "If pollen is passed from flower to flower, pollination occurs" is correct.

    The speed of light is faster than the speed of sound. True or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement "The speed of light is faster than the speed of sound" is true. This is because light travels at a speed of approximately 299,792 kilometers per second in a vacuum, while sound travels at a much slower speed of about 343 meters per second in dry air at 20 degrees Celsius. Therefore, light is significantly faster than sound.

    XX is the combination of sex chromosomes to produce a female child. True or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In humans, the combination of sex chromosomes XX typically leads to the development of a female child. This is because females inherit one X chromosome from each parent. On the other hand, males inherit one X chromosome from their mother and one Y chromosome from their father, resulting in the XY combination. Therefore, the statement that XX is the combination of sex chromosomes to produce a female child is true.

    Water starts boiling at 200 degrees Celcius temperature. True or false?

    • True

    • False

    Correct Answer

    Explanation
    The statement is false. Water starts boiling at 100 degrees Celsius temperature, not 200 degrees Celsius.

  • 6. 

    The remains of once-living organisms are known as meteorites.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. The remains of once-living organisms are not known as meteorites. Meteorites are actually fragments of asteroids or comets that have survived their journey through the Earth's atmosphere and have landed on the Earth's surface. The remains of once-living organisms are typically referred to as fossils.

  • 7. 

    Pollen that lands on the tip of another flower's pistil grows a tube down into the pistil, where the eggs are housed.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When pollen lands on the tip of another flower's pistil, it grows a tube down into the pistil. This tube allows the pollen to reach the eggs, which are housed within the pistil. Therefore, the statement is true.

    Rate this question:

  • 8. 

    Around day two, the plant begins to turn to reproduction, shifting from stem and leaf growth to flower development.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement suggests that around day two, the plant starts focusing on flower development instead of stem and leaf growth. However, this statement is false. Plants do not begin flower development around day two. Flower development occurs at a later stage in the plant's life cycle, after it has undergone sufficient growth and development of stems and leaves.

    Rate this question:

  • 9. 

    A plant that completes its life cycle in one growing season. It will grow, flower, set seed, and die.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement describes an annual plant, which is a type of plant that completes its life cycle in one growing season. This means that the plant will grow, produce flowers, set seeds, and then die within a year. Therefore, the correct answer is True.

    Rate this question:

  • 10. 

    Each seed of a plant contains a tiny, new plant called a chrysalis.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is incorrect. Each seed of a plant contains a tiny, new plant called an embryo, not a chrysalis. A chrysalis is the pupal stage in the life cycle of some insects, such as butterflies, and is not found within plant seeds.
