    What kind of metamorphosis does insect undergoes

    • Complete and incomplete metamorphosis

    • None of the above 

    • Small and big metamorphosis

    • I hate you

    Correct Answer
    A. Complete and incomplete metamorphosis
    Explanation
    Insects undergo two types of metamorphosis: complete and incomplete. Complete metamorphosis involves four distinct stages: egg, larva, pupa, and adult. In this process, the larva looks different from the adult and goes through a pupal stage where it undergoes a dramatic transformation before becoming an adult. In contrast, incomplete metamorphosis involves three stages: egg, nymph, and adult. The nymph resembles a smaller version of the adult and goes through gradual changes until it reaches adulthood.

    Is cuticle is regarded as the most abundant polymer on earth after cellulose?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The cuticle, which is a waxy layer that covers the outer surface of plants, is indeed considered to be the most abundant polymer on earth after cellulose. This is because the cuticle is present in a wide range of plant species and it serves as a protective barrier against water loss, UV radiation, and pathogens. The cuticle is composed of a complex mixture of lipid-based polymers, making it a significant component of the Earth's biomass.

    Rate this question:

    What class does millipede belongs to

    • Chelicerates

    • Myriapod

    • Hexapoda

    • Trilobites

    Correct Answer
    A. Myriapod
    Explanation
    Millipedes belong to the class Myriapoda. This class includes arthropods with elongated bodies and numerous legs. Millipedes are characterized by having two pairs of legs per body segment and a cylindrical body shape. They are part of the same class as centipedes and other multi-legged arthropods.

    Rate this question:

  • 10. 

    Is Arthropod covered in a resistance covering of cuticle?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Arthropods are indeed covered in a resistance covering of cuticle. The cuticle is a tough, flexible, and waterproof outer layer that provides protection to the arthropod's body. It helps prevent water loss, physical injury, and acts as a barrier against pathogens. The cuticle is made up of a protein called chitin, which gives it its strength and rigidity. This outer covering is molted periodically as the arthropod grows, allowing for growth and development. Overall, the presence of a cuticle is a defining characteristic of arthropods.

    The rest of the arthropods family that is having mandibule is called what?

    • Jaws

    • Mandibulata

    • Centipedes

    • Millipedes

    Correct Answer
    A. Mandibulata
    Explanation
    The correct answer is mandibulata. This term refers to the rest of the arthropods family that possess mandibles, which are powerful mouthparts used for biting and chewing. Mandibulata includes various groups such as insects, crustaceans, and myriapods. Jaws, centipedes, and millipedes are not accurate answers as they do not encompass the entirety of arthropods with mandibles.

     what kind of consumers are crustaceans?

    • Hebivores

    • Canivores

    • All of the above

    • Dentrivores

    Correct Answer
    A. All of the above
    Explanation
    Crustaceans are a diverse group of organisms that include various types of consumers. They can be herbivores, feeding on plants and algae, carnivores, preying on other animals, and detritivores, consuming dead organic matter. Therefore, the correct answer is "all of the above" as crustaceans can exhibit different feeding behaviors depending on the species and their ecological role.

    The primary internal cavity of an insect is called

    • Haemocoel 

    • Circulatory system

    • Valve

    • Sugar

    Correct Answer
    A. Haemocoel 
    Explanation
    The primary internal cavity of an insect is called the haemocoel. This is the main body cavity where the insect's circulatory system operates. It is filled with a fluid called haemolymph, which functions similarly to blood in other animals. The haemocoel is responsible for transporting nutrients, hormones, and waste products throughout the insect's body.

    Rate this question:

  • 15. 

    Growth in arthropod can be achieved by the process of 

    • Metamorphosis

    • Transpiration

    • Ecdysis

    • None of the above

    Correct Answer
    A. Ecdysis
    Explanation
    Ecdysis refers to the process of shedding or molting the outer layer of the exoskeleton in arthropods. This allows for growth and development as the arthropod grows larger and needs a larger exoskeleton. Metamorphosis, on the other hand, is a process of transformation in insects, where they undergo distinct stages of development, such as egg, larva, pupa, and adult. Transpiration is the process of water movement through a plant and is not related to arthropod growth. Therefore, the correct answer is ecdysis.

    Rate this question:

  • 16. 

    The unique structure found in centipedes is called what?

    • Pincer like structure

    • Forcipules

    • Mandibles

    • Venom

    Correct Answer
    A. Forcipules
    Explanation
    Centipedes have a unique structure called forcipules. Forcipules are specialized appendages located near the head of the centipede, which resemble pincers or claws. They are used for capturing and immobilizing prey, as well as for defense. Unlike mandibles, which are commonly found in insects, forcipules are exclusive to centipedes and play a crucial role in their hunting and survival strategies. Venom, on the other hand, refers to the toxic substance that centipedes inject into their prey using their forcipules, making it an incorrect answer choice.

    Rate this question:

  • 17. 

    Does insect blood carry oxygen?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Insects do not have blood vessels or a circulatory system like humans. Instead, they have an open circulatory system where their blood, called hemolymph, flows freely within their body cavity. Hemolymph does not carry oxygen like human blood does. Instead, oxygen is delivered directly to the insect's tissues through a network of tiny tubes called tracheae. Therefore, the correct answer is false.

    • Esther

    • Ecdysis

    • Instar

    • Moulting

    Correct Answer
    A. Instar
    Explanation
    An instar is a phase between two periods of moulting in the development of an insect larva or other invertebrate animal. During this phase, the larva or animal undergoes growth and development before shedding its old exoskeleton and forming a new one. This process allows the larva to increase in size and progress through different stages of development.

    All of these are correct about Arthropod except

    • They are triploblastic,

    • Metamerically segmented coelomates

    • Bilaterally symmetrical

    • Radially symmetrical

    Correct Answer
    A. Radially symmetrical
    Explanation
    Arthropods are triploblastic, meaning they have three germ layers during development. They are also metamerically segmented, which means their bodies are divided into repeating segments. Arthropods are bilaterally symmetrical, meaning that their bodies can be divided into two equal halves along a single plane. However, they are not radially symmetrical, as this type of symmetry is typically found in animals like jellyfish and sea anemones.

  • 27. 

    Process of moulting is controlled by?

    • Epidermis

    • Ecoysone

    • None of the above

    • Instars

    Correct Answer
    A. Ecoysone
    Explanation
    The process of moulting, which is the shedding of the old exoskeleton and the formation of a new one, is controlled by ecdysone. Ecdysone is a hormone that regulates the moulting process in arthropods. The epidermis is the outermost layer of the skin, but it does not directly control the moulting process. Instars refer to the developmental stages between moults in arthropods and are not responsible for controlling the moulting process. Therefore, the correct answer is ecdysone.
