Which sequence places the developmental structures in the correct order?

Question

Quizplus · Accepted Answer

The correct sequence of developmental structures is morula, blastula, and then gastrula. The morula is a solid ball of cells that eventually undergoes cell division to form the blastula, which is a hollow ball of cells. The blastula then goes on to form the gastrula, which is the stage in development where the three germ layers begin to form and differentiate into the various organs and tissues of the body. Therefore, choice D is the correct sequence.
