Question

according to the module presentation, which characteristic of the ecdysozoans evolved independently in the vertebrata? a. Exoskeleton b. Segmentation c. Bilateral symmetry d. Endoskeleton

Answer 1

The characteristic of the ecdysozoans that evolved independently in vertebrates is the endoskeleton. Hence the correct answer is option D.

Step-by-step explanation:

In vertebrates, the characteristic that evolved independently is the endoskeleton. Ecdysozoans, a group of animals that includes arthropods, have an exoskeleton, whereas vertebrates have an internal skeleton called an endoskeleton. This is a significant difference in body plan and the presence of an endoskeleton allows for greater flexibility and mobility in vertebrates. Hence the correct answer is option D.
