Question

Which of the following trait is not a characteristic of frog?

• A. Thin, scaleless skin
• B. Aquatic reproduction
• C. Amniote egg
• D. Cutaneous respiration

Answer 1

The correct option is C Amniote egg

Amniote egg is the characteristics of terrestrial animals which lay eggs on land. Amniote provides the nutrition and protection to the developing embryo. Frogs are known as anamniotes as they do not develop an amnion and exchange oxygen, carbon dioxide and waste metabolites with the surrounding water directly due to the thin covering on the egg. The water helps in the diffusion of waste products (particularly ammonia) and prevents its accumulation.

So, the correct answer is option C.
