Answer 1

Hey dear ‼️

The notochord is a flexible rod made out of a material similar to cartilage. If a species has a notochord at any stage of its life cycle, it is, by definition, a chordate. In vertebrates the notochord becomes part of the vertebral column. The notochord lies along the anteroposterior ("head to tail") axis, is usually closer to the ventral than the dorsal surface of the animal, and is composed of cells derived from the mesoderm. The notochord has been observed to have many functions including developmental functions.
