Protostome Characteristics Generally Include Which of the Following

Question

Protostome characteristics generally include which of the following?
A)a mouth that develops secondarily, and far away from the blastopore
B)radial body symmetry
C)radial cleavage
D)determinate cleavage
E)absence of a body cavity

Accepted Answer

Protostomes are characterized by determinate cleavage, where the fate of each cell is determined early in development. They also typically have a mouth that develops from or near the blastopore, although this is not always the case. Radial body symmetry and radial cleavage are characteristics of deuterostomes, while the presence or absence of a body cavity can vary between protostomes and deuterostomes.
