The types of mutations include: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. A nonsense mutation is also a change in one DNA base pair.

The Earth's core is made up primarily of the metals nickel and iron. The inner core is mostly iron, while the outer core is composed of both nickel and iron. The inner core is very hot at 9,000 to 13,000 degrees Fahrenheit, however, the iron is not liquid because of the pressure of the Earth pressing in on it.
The inner and outer core are made of the same material, chiefly the metal Iron, with small amounts of Nickel and some other lighter elements. However, geologists have discovered through a variety of experiments that as the pressure on a solid material increases, its melting temperature increases as well.
