C. One amino acid would change due to a substitution.

Explanation:

The amino acid sequences before and after the mutation are given at the top. The one on the left has the codon CAG while the one on the right has the codon CGG. The rest of the sequences are identical to eachother. This is a subsitution mutation, as only one letter changed.

Using the codon chart, you can see that CAG would make the amino acid Glutamine, while CGG would make the amino acid Arginine. Therefore, the answer is C.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
