    Roundworms can be parasites and decomposers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Roundworms can be both parasites and decomposers. As parasites, they live inside the bodies of other organisms and obtain nutrients from them, often causing harm or disease. As decomposers, they break down organic matter and contribute to the process of decomposition, aiding in the recycling of nutrients in the ecosystem. Therefore, the statement that roundworms can be parasites and decomposers is true.

    Amphibians spend part of their life in water and next part on land.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Amphibians are known for their ability to live both in water and on land. They typically start their lives as aquatic larvae, breathing through gills, and then undergo metamorphosis into adults that can breathe through lungs and live on land. This dual lifestyle is a defining characteristic of amphibians and sets them apart from other animal groups. Therefore, the statement that amphibians spend part of their life in water and the next part on land is true.

    Placental mammals are those mammals born fully developed.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Placental mammals are a group of mammals that give birth to fully developed offspring. Unlike marsupials or monotremes, which give birth to underdeveloped young and continue their development outside the womb, placental mammals have a placenta that nourishes the fetus during gestation. This allows them to give birth to fully developed young that are capable of independent survival. Therefore, the statement that placental mammals are born fully developed is true.

    Rate this question:

  • 20. 

    Which of the following animals is a placental mammal?

    • A.

      Koala bears

    • B.

      Opossum

    • C.

      Giraffe

    • D.

      Wallabies

    Correct Answer
    C. Giraffe
    Explanation
    The correct answer is giraffe because giraffes are placental mammals. Placental mammals are a group of mammals that give birth to live young ones, nourished by a placenta. Koala bears, opossums, and wallabies are marsupials, which means they give birth to relatively undeveloped young ones that continue to develop in a pouch. Giraffes, on the other hand, have a longer gestation period and give birth to well-developed young ones.
