Answer 1

The notochord is a flexible rod-shaped body found in embryos of all
chordates. It is composed of cells derived from the mesoderm and defines the
primitive axis of the embryo. In some chordates, it persists throughout life as
the main axial support of the body, while in most vertebrates it becomes the
vertebral body of the vertebral column.The notochord is found ventral to the
neural tube. It is like the the first "backbones" serving as support structures
in the primitive chordates
