Which of the following best explains a way that a molecular clock can be used?
a.) the number of dna mutations in an organism is measured over time to determine how long it will take for a new species to evolve.
b.) the number of dna mutations in a species is compared to the number of dna mutations in another species to determine the relative amount of time each species has been evolving.
c.) the number of differences in a specific dna sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
d.) the number of differences in the dna sequences of two organisms of the same species is averaged to determine how many years of evolution have occurred
providing your proof would be nice : )

The diagram below shows the layers of a rock having a trilobite: a rock column labeled rock is shown. the column has three layers. the bottommost layer of the rock has one shaded rhomboid shape, the middle layer has a rhombus with a diagonal along with two identical organisms marked as, trilobite, in the key, the top layer has two semicircles. a key is shown on the right side of the diagram. the shaded rhombus is marked as a, the rhombus with the diagonal is marked as b, the semicircle is marked as c which statement about the rock fossils is true?
