Question

question 7
which of the following is true about the fate of the notochord in vertebrates?
the notochord eventually degrades into the vertebral discs
the notochord eventually turns into the spinal cord
the notochord stays intact to provide stability for swimming and running
the notochord turns into the peripheral nervous system

Explanation:

In vertebrates, the notochord is a transient embryonic structure. It eventually degrades and contributes to the formation of the vertebral discs. The spinal cord develops from the neural tube, not the notochord. The notochord doesn't stay intact for locomotion - it is replaced by the vertebral column. And it does not form the peripheral nervous system.

Answer:

The notochord eventually degrades into the vertebral discs
