    Incomplete Metamorphosis

    • A.

      Egg, nymph, adult.

    • B.

      Adult, egg, pupa.

    • C.

      Roundworms

    Correct Answer
    A. Egg, nymph, adult.
    Explanation
    This answer is correct because it accurately describes the life cycle of insects that undergo incomplete metamorphosis. In this type of metamorphosis, the insect goes through three stages: egg, nymph, and adult. The egg hatches into a nymph, which resembles a smaller version of the adult but lacks wings and reproductive organs. The nymph then goes through a series of molts, growing larger and developing wings and reproductive organs, until it reaches its final adult form. Therefore, the correct order is egg, nymph, adult.

    • C.

      Tubules

    • D.

      Setae

    Correct Answer
    D. Setae
    Explanation
    Setae are bristle-like structures found on the body of an earthworm that aid in its movement. These tiny hairs provide traction and grip on the ground, allowing the earthworm to crawl and burrow through soil and other substrates. The setae anchor the worm's body to the surrounding environment, preventing it from slipping or sliding as it contracts and expands its muscles to move forward. Therefore, setae play a crucial role in facilitating the earthworm's locomotion.

    Arachnids breathe by means of ____________.

    • A.

      Diffusion

    • B.

      Gills

    • C.

      Book Lungs

    • D.

      Spinnerets

    Correct Answer
    C. Book Lungs
    Explanation
    Arachnids, such as spiders, scorpions, and ticks, breathe through specialized respiratory organs called book lungs. These book lungs are located in the abdomen and consist of thin, leaf-like structures called lamellae. Oxygen from the surrounding air diffuses into the lamellae and is then transported to the spider's cells for respiration. This adaptation allows arachnids to effectively obtain oxygen without the need for gills or other respiratory structures.

    Most newly hatched insects do not resemble their parents because the process of ____________.

    • A.

      Reproduction

    • B.

      Complete Metamorphosis

    • C.

      Birth

    • D.

      Fertilization

    Correct Answer
    B. Complete Metamorphosis
    Explanation
    Most newly hatched insects do not resemble their parents because the process of complete metamorphosis occurs. Complete metamorphosis is a type of development in insects where they go through distinct stages: egg, larva, pupa, and adult. In each stage, the insect looks different and has different behaviors and functions. This allows the insect to adapt to different environments and food sources as it grows. Therefore, the lack of resemblance between newly hatched insects and their parents is due to the process of complete metamorphosis.
