<u>Substituion mutation</u> is responsible for small changes in a trait.
Explanation:
This kind of mutation merely changes the type of nucleotide in the DNA sequence. The mutation does not cause a frameshift as would a deletion of addition mutation.
A substitution mutation would at worst change an amino acid in the translated protein. This would likely have a slight effect on how the protein folds into an active protein. On the other hand, mutations that cause frameshifts have the biggest effect on the proteins. They change all the amino acids of a protein downstream of the point of mutation.

Answer:
"Ionosphere and Exosphere" is the right response.
Explanation:
- The ionosphere seems to be the interface through which the Northern side lights originally come, or perhaps the Aurora Borealis. This same radioactivity including its sun throughout the ionosphere ionized particles the particulates emitting the logo lighting system of Aurora.
- The exosphere, having started from five hundred kilometers, would be the outermost part of that same thermosphere. This same exosphere appears to contain slightly heavier gasses including such helium.
