Which type of mutation has a larger effect, a point mutation or a frameshift mutation?

a frameshift mutation would likely have a larger effect because it changes many codons.

(*a point mutation might also have a large effect, for example, if it changes a codon for an amino acid into a stop codon)

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.
