Suppose a scientific team is trying to recreate the energy-producing reactions that occur in the sun. what would they need for the experiments? a: hydrogen atoms, heat, and pressure b: hydrogen atoms, helium atoms, heat, pressure, and energy c: helium atoms and energy d: helium atoms and hydrogen atoms

Option (A) is the correct answer.

Explanation:

Nuclear fusion is a  reaction in which two small nuclei combine together to result in the formation of a larger nuclei.

In the Sun, two hydrogen nuclei fuse together to form a larger nuclei. Also, nuclear fusion reaction requires energy to bring the nuclei close together by overcoming the forces of repulsion caused by protons.

Therefore, in order to recreate the energy-producing reactions that occur in the Sun, they need hydrogen atoms, heat, and pressure.

Pressure is also necessary as it will add to bring the nuclei close together.
