The nature of exoskeleton in echinoderms is
1 calcareous
2 chitinous
3 siliceous
4 tunicin
Explanation:
A The calcareous exoskeleton is found in the phylum echinodermata. The Echinodermata have spiny texture skin. They have an exoskeleton made up of spicules. The spicules are spiny structures that are made up of calcium carbonate minerals.

Which of the following is a mismatch pair?
1 Scales - Reptilia
2 Comb plates - Mollusca
3 Choanocytes - Porifera
4 Parapodia - Annelida
Explanation:
B Comb plates : - Comb plates are large ciliary structure uniquely seen in comb jellies (ctenophores). A comb plate is constructed from tens of thousands of cillia that are bundled together by structures called compart menting camellae. - Pleurobrachia is the organism in which comb plates are found. It is not found in mollusca.
