The body of which is called metamerically segmented?
Correct answer: C. Annelids
- A. Cnidarians
- B. Nematodes
- C. Annelids
- D. Sponges
Explanation
The body of Annelids is called metamerically segmented. Annelids are a group of worms, including earthworms and leeches, that exhibit metamerism, which means their bodies are divided into a series of repeating segments or metameres. Each segment typically contains similar structures and can perform similar functions, such as locomotion using segmental muscles and housing specific internal organs. This segmentation is a characteristic feature of annelids and sets them apart from the other phyla listed.
