All of these are correct about Arthropod except
- A.
They are triploblastic,
- B.
Metamerically segmented coelomates
- C.
Bilaterally symmetrical
- D.
Radially symmetrical
Correct Answer
D. Radially symmetricalExplanation
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.Rate this question:

Is Arthropod covered in a resistance covering of cuticle?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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.Rate this question:

Is cuticle is regarded as the most abundant polymer on earth after cellulose?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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:

Epicuticle
- B.
Exocuticle
- C.
Mesocuticle
- D.
Endocuticle
Correct Answer(s)
A. Epicuticle
B. Exocuticle
D. EndocuticleExplanation
The cuticles are divided into three layers: the epicuticle, exocuticle, and endocuticle. The epicuticle is the outermost layer and acts as a protective barrier against water loss and external damage. The exocuticle is the middle layer and provides structural support and strength to the cuticle. The endocuticle is the innermost layer and is responsible for flexibility and elasticity. Together, these three layers make up the cuticle, which is essential for the protection and function of various organisms.Rate this question:

- A.
Oligochaeta
- B.
Polychaeta
- C.
None of the above
- D.
Echinoidea
Correct Answer
B. PolychaetaExplanation
Arthropods share many characteristics with polychaeta. Polychaeta are a class of annelid worms that have segmented bodies and numerous bristle-like appendages called parapodia. Arthropods also have segmented bodies and appendages, such as legs or antennae. Both groups have a similar body plan and exhibit bilateral symmetry. Additionally, both arthropods and polychaeta have a well-developed nervous system and a closed circulatory system. Therefore, it can be concluded that arthropods have many shared characteristics with polychaeta.Rate this question:

Growth in arthropod can be achieved by the process of
- A.
Metamorphosis
- B.
Transpiration
- C.
Ecdysis
- D.
None of the above
Correct Answer
C. EcdysisExplanation
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:

What kind of metamorphosis does insect undergoes
- A.
Complete and incomplete metamorphosis
- B.
None of the above
- C.
Small and big metamorphosis
- D.
I hate you
Correct Answer
A. Complete and incomplete metamorphosisExplanation
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.Rate this question:

A phase between two periods of moulting in the development of an insect larva or other invertebrate animal is called?
- A.
Esther
- B.
Ecdysis
- C.
Instar
- D.
Moulting
Correct Answer
C. InstarExplanation
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.Rate this question:

Process of moulting is controlled by?
- A.
Epidermis
- B.
Ecoysone
- C.
None of the above
- D.
Instars
Correct Answer
B. EcoysoneExplanation
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.Rate this question:

Does insect blood carry oxygen?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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.Rate this question:
