Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.
The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.
Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

Answer:
abnormal development or growth especially of cells.
<span><span>Mitosis is the process in which cells divide to
form new cells. The cell that is being described under the microscope is
already in the Anaphase stage in mitosis.
Anaphase is the process in which two sister chromatids separate and move to
opposite poles of the cell. These two sister chromatids contain identical
copies of DNA that are joined at the middle called centromere. The chromosomes
are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two
separate poles. The mitotic process then proceeds to the
Telophase.</span>
