Answer 2

The common feature between roundworm and silkworm is- (C) Triploblastic animals

• In both roundworm and silkworm, organ system level of body organisation is found.
• Roundworms belong to the Phylum Aschelminthes, members of which are triploblastic with bilateral symmetry. An excretory tube helps in the removal of body wastes through the body cavity.
• Silkworms belong to the Phylum Arthropoda, members of which are triploblastic with bilateral symmetry. The presence of Malpighian tubules is a characteristic feature of arthropods. Malpighian tubules excrete nitrogenous products outside the body.
