Question

How do you differentiate a frog from a toad?

• A. Frog has no exoskeleton but toad had scales
• B. Frog respires through lungs but toad respires through skin
• C. Frog has a tail but toad has no tail
• D. Frog has no parotid glands but toad has a pair of parotid glands

Answer 1

The correct option is D Frog has no parotid glands but toad has a pair of parotid glands

Frogs do not have exoskeleton as they are vertebrates but toads do not have scales either. Both frogs and toads respire using lungs and skin. Frogs do not have tail. Parotid glands are poisonous glands present on the head of toads.

Hence option D is the correct answer.
