Which best describes how dna is used as a molecular clock? (2 points)
the number of mutations in dna is compared between two species.
the total amount of dna is compared between two species.
the percent of carbon in dna is compared between parent and offspring.
the total mass of dna is compared between parent and offspring.

The scales shown in the introduction measure mass, or the amount of matter in a particular object. the scientific law of conservation of mass states that matter cannot be created or destroyed during a chemical reaction, but it can change from one form to another. did the simulation support this scientific law? explain why or why not.
