Which type of mutation results in receiving an extra chromosome?

Every second of every day our Sun converts about 4.2 million metric tons (4,200,000,000 kilograms) of hydrogen into helium using a nuclear fusion process. During this nuclear reaction, a small portion of matter is converted to an enormous amount of energy. It is this output that provides the energy for photosynthesis and for heating our atmosphere and oceans.

In this lesson, you will learn the details of the nuclear fusion process. You will also learn about another important nuclear reaction called fission and some useful applications of it.

uh two lol

a physical change is being made.
