Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.
The cells show characteristics of tumors.
Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.

A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.</span>

Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.
