Which of the following are true about Mollusca?
1 Triploblastic and radial symmetry
2 Bilateral symmetry and calcareous shell
3 Radula and diploblastic
4 Calcareous shell and radial symmetry
Explanation:
B Mollusca are the second largest animal phylum. They are bilaterally symmetrical, triploblastic, coelomate animals. They have a $\mathrm{CaCO}_{3}(\mathrm{Calcareous})$ shell. Radula are specialized structure in mollusca for feeding.

Select the correct matching:
1 Phylum - Hemichordata, Character - Notochord, Example - Balanogloss
2 Phylum - Mollusca, Character - Radula, Example - Dentalium
3 Phylum - Platyhelminthes, Character - Coelomate, Example - Dugesia
4 Phylum - Coelenterata, Character - All marine, Example - Hydra
Explanation:
B The radula is tile-like structure used by mollusca for feeding, sometimes compared to a tongue. Dentalium belongs to phylum Mollusca. - Hemichordates consist of stomochord in the collar area instead of notochord. Stomochord is similar in structure to the notochord. Balanoglossus belongs to phylum Hemichordata - Platyhelminthes have no circulatory system or body cavity (coelom). Ex- Dugesia, Planaria. - Coelenterates are all aquatic mostly marine, some (fresh water) animals. Hydra belongs to phylum Coelenterata.

Torsion of visceral mass is seen in animals belonging to class
1 Cephalopoda
2 Scaphopoda
3 Amphineura
4 Gastropoda
Explanation:
D Gastropods transform the symmetric bodyplane into a highly asymmetric one through a unique process called torsion. Torsion is about $180^{\circ}$ rotation. Although the oneset of torsion and its completion are readly observed in several species.

Ctenidia are the respiratory organs of the following
1 Arthropoda
2 Annelida
3 Mollusca
4 Porifera
Explanation:
C Ctenidia are the respiratory organs of mollusks. They are specialized structures that help mollusks like clams, mussels, and snails extract oxygen from water and eliminate carbon dioxide.
