Question

Q: Look at the illustration in Figure 25-3. Which of the following internal characteristics would you expect this animal to have?
Answer choices:
A.coelom
B.deuterostome
C.radial symmetry
D.a notochord

Answer 1

earthworms have coelom so the answer has to be A

Answer 2

Answer: Option A; Coelom

Earthworms are coelomate species. They are included under the phylum Annelida, which have bilateral symmetry. They don't have radial symmetry, that's why option C is incorrect. Notochord is present in chordates, and absent in earthworms, thus option D is also incorrect. Earthworms are not deuterostomes, instead they protostomes. Thus, option B is also incorrect.
