question 6
during nuclear fusion in the sun, which of the following occurs?
atomic nuclei split apart.
the aurora australis appears.
hydrogen nuclei combine to produce a helium nucleus.
a solar eclipse results.

Explanation:

Nuclear fusion in the sun involves hydrogen - 1 nuclei (protons) fusing to form a helium - 4 nucleus. Atomic nuclei splitting apart is nuclear fission. The aurora australis is related to charged particles interacting with Earth's magnetic field and atmosphere. A solar eclipse is due to the alignment of the Sun, Moon, and Earth.

Answer:

Hydrogen nuclei combine to produce a helium nucleus.
