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

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.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
