Questions and Answers
  • 1. 

    Which of the following are characteristics of phylum Arthropoda?  

    • A.

      Have jointed apendages

    • B.

      Exoskeleton

    • C.

      Have a backbone

    • D.

      Segmented and long bodied

    • E.

      Bell shape

    Correct Answer(s)
    A. Have jointed apendages
    B. Exoskeleton
    Explanation
    The characteristics of phylum Arthropoda include having jointed appendages and an exoskeleton. Arthropods, such as insects, spiders, and crustaceans, have limbs that are divided into segments and can bend at joints. Their exoskeleton is a hard outer covering that provides support and protection. However, they do not have a backbone or a bell shape.

      Chordata

    • B.

      Mollusca

    • C.

      Annelida

    • D.

      Platyhelminthes

  • 3. 

    Chordates can be described as animals - 

    • A.

      That contain a backbone

    • B.

      That reproduce asexually

    • C.

      That produce their own food

    • D.

      That only live in the ocean

    Correct Answer
    A. That contain a backbone
    Explanation
    Chordates can be described as animals that contain a backbone because chordates are a phylum of animals that possess a notochord, which is a flexible rod-like structure that provides support and stability. The notochord eventually develops into a backbone or vertebral column in most chordates. This distinguishing feature sets chordates apart from other animal groups and is a defining characteristic of this phylum.

      Echinoderm

      Arthropoda

    • D.

      Mollusca

    Correct Answer
    C. Arthropoda
    Explanation
    The correct answer is Arthropoda. Arthropoda is a phylum that includes animals with jointed appendages, segmented bodies, and an exoskeleton. This animal is likely to belong to the phylum Arthropoda because it exhibits these characteristics. Echinoderm, Platyhelminthe, and Mollusca are different phyla that do not match the description of the animal in question.

    Which phylum does this animal belong?

      Cnidaria

    • D.

      Annelida

    Correct Answer
    C. Cnidaria
    Explanation
    The correct answer is Cnidaria. Cnidaria is a phylum that includes animals such as jellyfish, coral, and sea anemones. These animals have radial symmetry and stinging cells called cnidocytes. They typically have a sac-like body plan and a single opening that serves as both the mouth and anus. Echinoderma is the phylum that includes animals like starfish and sea urchins, which have a spiny skin and a unique water vascular system. Mollusca is the phylum that includes animals like snails, clams, and octopuses, which have a soft body and often a hard shell. Annelida is the phylum that includes segmented worms like earthworms and leeches.

    Rate this question:

  • 6. 

    Which statement is true of all mollusks?

    • A.

      They are soft-bodied invertebrates

    • B.

      They use jet propulsion to escape enemies

    • C.

      They only live in salt water

    • D.

      They are vertebrates that breathe with lungs

    Correct Answer
    A. They are soft-bodied invertebrates
    Explanation
    All mollusks share the characteristic of being soft-bodied invertebrates. This means that they lack a backbone and have a soft body covered by a protective shell. This is a defining feature of the entire mollusk phylum, which includes animals such as snails, clams, and octopuses. While some mollusks do live in salt water, it is not true that they only live in salt water. Additionally, mollusks do not have vertebrates and do not breathe with lungs.

    Rate this question:

  • 7. 

    An animal that does NOT have a backbone is called what?

    • A.

      Vertebrate

    • B.

      Invertebrate

    Correct Answer
    B. Invertebrate
    Explanation
    An animal that does not have a backbone is called an invertebrate. Invertebrates make up the majority of animal species and include insects, worms, mollusks, and jellyfish, among others. Unlike vertebrates, which have a backbone or spinal column, invertebrates have a wide range of body structures and support systems. This distinction is important in classifying and understanding the diversity of animal life on Earth.
