it is called a notochord.
Notochord is a supporting structure found in lower chordates and in embryos of all higher chordates. It functions as a major axial supporting structure just as vertebral column does in our body.

in human body they are hard supporting structures called bones
The paragraph(s) between the introduction and conclusion are called body paragraph(s).
yes, I think it's called coelom. An organism with a true body cavity is called a eucoelomate. This means that the body cavity exists between the inner layer of mesoderm and the outer layer of mesoderm. A pseudocelomate kind of has a body cavity but it is the space between the endoderm and mesoderm. This is not a true body cavity because it is not mesoderm on mesoderm.
One characteristic shared by all chordates is the presence of a notochord, a flexible rod that provides structural support. Humans, being classified under the phylum Chordata, possess a notochord during their embryonic development that eventually develops into the spinal column.

Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.

True coelom is body cavity lined by mesothelium on both sides as in chordates .
No , its actually called metastasis.
It runs along the dorsal side of the body.
A supporting body of a paragraph provides evidence, examples, or explanations that develop the main idea or topic sentence. It reinforces the main point by offering details and information that help to clarify or strengthen the argument or point being made in the paragraph.
