Question

The different between a protostome and a duerostome is that?

A. the dueterostome only has two germ layers
B. A protostome always develops into an acoelomate
C. The blastophore in a duesterostome develops into the animal's anus
D. Only protostomes can develop into radically symmetrical adults.

Answer 1

Protostomia are a taxon of animals. Together with the deuterostomes and a few smaller phyla, they make up the Bilateria, mostly comprising animals with bilateral symmetry and three germ layers. The major distinctions between deuterostomes and protostomes are found in embryonic development.

Deuterostomes are a superphylum of animals. They are a subtaxon of the Bilateria branch of the subregnum Eumetazoa, and are opposed to the protostomes. Deuterostomes are distinguished by their embryonic development; in deuterostomes, the first opening (the blastopore) becomes the anus, while in protostomes it becomes the mouth.
