D Correct answer
Explanation

Animals show different types of body organization. They are multicellular.
Animals can be Asymmetric, Radial and Bilateral symmetric.  Most of the animals are triploblastic. They obtain nutrients by ingestion, so they have a heterotrophic mode of nutrition. They store glycogen as the reserve food material.
Hence, the correct answer is 'Storage of carbohydrate as starch'.

Which of the following is correct matching set of Phylum and its three examples?

  1. Annelid - Nereis, Pheretima and Apis

  2. Echinodermata - Ophiura, Antedon and Cucumaria

  3. Mollusca - Dentalium, Pinctada, Hirudinaria

  4. Aschelminthes - Ancylosytoma, Wuchereria and Asterias
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Ophiura or the serpent star is a species of the brittle star in the order Ophiurida belonging to the phylum Echinodermata and class Ophiuroidea.
  • Antedon is a genus of free-swimming, stemless crinoids belonging to the phylum Echinodermata and class Crinoidea.
  • Cucumaria is a genus of sea cucumbers belonging to the phylum Echinodermata and class Holothuroidea.
  • Hence Echinodermata - Ophiura, Antedon, and Cucumaria is a correct matching set of Phylum and its three examples.
  • So, the correct answer is 'Echinodermata - Ophiura, Antedon, and Cucumaria'.
