  • Question 1
    1 / -0
    Haemocoel occurs in
    Solution
    Option (D) Arthropoda
    The body cavity is reduced and filled with blood, thus it is called haemocoel. The animals belonging to phylum Arthropoda has haemocoel. Haemocoel is the fluid found in the circulatory system of phylum arthropoda.

  • Question 2
    1 / -0
    Body cavity not lined by mesoderm and directly connected to archenteron occurs in
    Solution
    Option (B) Nematodes
    Nematoda consists of the nematodes. They are characterized by their long, thin, tube like appearance that lacks a visually distinct head or tail. Nematides exist as free living organisms in terrestrial and aquatic environments.

  • Question 3
    1 / -0
    Coprophagous animals are
    Solution
    A coprophagous organism is one that eats the faeces/excrement of another animal. Many insect species are coprophagous and often specialise in the consumption of faeces from large herbivores. Some of the most well-known coprophagous insects are the dung beetles 
    So answer is C
  • Question 4
    1 / -0
    Mouth develops first in embryo and anus later on in ___________.
    Solution
    • Protostomes are primitive invertebrates developing the mouth (from blastopore) before the anus during embryonic development including the arthropods (e.g., insects, crabs), mollusks (clams, snails), and annelid worms, etc.
    • Deuterostomes are animals in which anus is formed before any other opening during embryonic development, include chordates and echinoderms. 

    So, the correct answer is option C.
  • Question 5
    1 / -0
    Which animals do not exhibit radial symmetry?
    Solution
    In radial symmetry, the organism will have a body plan that can be divided into similar halves by passing a plane at any angle along a central axis. This is observed in the members of Phylum Coelenterata, Ctenophora, and Echinodermata.
    Annelids show bilateral symmetry where the body of the organism can be divided into two halves that are mirror images along a median axis. 

  • Question 6
    1 / -0
    The kind of coelom represented in the diagram is characteristic of

    Solution
    The roundworm belongs to the group of Nematoda. These are elongated tube-like organisms.
    These organisms have bilateral symmetry. They have a cavity present between the body wall and the gastrointestinal cavity. The cavity present in the middle is known as pseudocoelom.
    This cavity is formed from the mesoderm and endoderm. The internal organs are placed in this cavity. 

    Thus, the correct answer is option C. 
  • Question 7
    1 / -0
    Annelida do not have the following character
    Solution
    Enterocoely describes both the process by which some animal embryos develop and the origin of the cells involved. In enterocoely, a mesoderm is formed in a developing embryo, in which the coelom appears from pouches growing and separating from the digestive tract 
    So answer is B
  • Question 8
    1 / -0
    Which is sanguivorous?
  • Question 9
    1 / -0
    Which one is the group of bilaterally symmetrical and triploblastic animals?
    Solution
    Nematodes 
    $$ \rightarrow $$ The body of nematodes is circular, hence
    also called round worms
    $$ \rightarrow $$ These may be free-living or parasitic
    $$ \rightarrow $$ Organ -system level of body organisation 
    $$ \rightarrow $$ Bilaterally symmetrical
    $$ \rightarrow $$ triploblastic
    $$ \rightarrow $$ pseud o codomate
    $$ \rightarrow $$ Seperate sexes 
    $$ \rightarrow $$ Internal fertilisation 
    Examples - Ascaris, Wachreria, Anylostma

  • Question 10
    1 / -0
    Formation of mesoderm as evaginated sacs from archenteron is characteristic of
    Solution
    The formation of mesoderm as evaginated sacs from the archenteron is the characteristic feature of Pentaceros. In Pentaceros tip of the larval archenteron forms the mesenchyme which later on gives rise to two pouches. Two pouches of mesenchyme connect anteriorly to form a U-shaped coelom.
    So, the correct answer is 'Pentaceros'
