Answer:
1-Vertebrae: A series of short, stiff vertebrae are separated by joints. This internal backbone protects the spinal cord. The joints between the vertebrae let the backbone bend.
2-Gill arches: Gill arches in the pharynx of fish and some amphibians support the gills. In the majority of vertebrates some of the arches have evolved into other organs, such as jaws.
3-Bones: support and protect the body's soft tissues and provides points for muscle attachment.
