key difference between protostomes and deuterostomes? A. protostomes represent a lineage of bilaterally symmetrical animals, whereas deuterostomes represent a lineage of radial symmetrical animals B. protosomes are animals with soft exteriors and deuterostomes are animals with hard exteriors (i.e., shells) C. the protostome gut develops from front to back, so the first opening is the mouth. The deuterostome gut develops back to front, and the second opening becomes the mouth D. protostomes represent animals that are prokaryotes, the deuterostomes represent all other animals E. the protostome gut develops from back to front and the second opening becomes the mouth. The deuterostome gut develops from front to back, so the first opening is the mouth
