Question

Which one from the following is correct?

• A. Flatworms are eucoelomates
• B. Fishes are radially symmetrical
• C. Birds are poikilothermic
• D. Earthworm is metamerically segmented

Answer 1

The correct option is D Earthworm is metamerically segmented

Flatworms lack coelom and are hence called acoelomate animals. Fishes are bilaterally symmetrical animals. Birds are homeotherms and maintain a constant body temperature with the help of internal body metabolism. Earthworm is an annelid having a metamerically segmented body. The segments have a repetition of organs.

So, the correct answer is option D.
