Please select the best answer from the choices provided

T
F

Answer 1

Extremely high temp and pressure are in fact necessary TRUE

Answer 2

True

Step-by-step explanation:

Fusion reactions are those in which two nuclei of smaller mass atoms unite to form a larger nucleus. Star fusion takes place at its center, at high temperatures and high pressures. In the sun it occurs mainly in the fusion of hydrogen isotopes to the formation of helium isotopes.

Since these reactions occur at high temperatures and high pressures, the nucleus of stars is the ideal place for them to occur. These are chain reactions, that is, the products formed initiate new reactions and may continue to merge with other nuclei, and so on.
