A body plan consisting of repeating segments,which are modified during development into structures such as vertebrae,ribs,and muscles,depends on modification of early developmental structures called

B) somites.
C) parenchyma.
D) neural crest cells.
E) lateral plate mesoderm.

Question

Quizplus · Accepted Answer

The body plan described in the question is characteristic of segmented animals, such as vertebrates, and is based on the repeated structures called somites. These somites differentiate into various structures during development, including vertebrae, ribs, and muscles. Therefore, the correct answer is (B) somites. The other choices - interneurons, parenchyma, neural crest cells, and lateral plate mesoderm - are not directly involved in the formation of the segmented body plan.
