Agroup of scientists determines that a mitochondrial dna sequence shared by two species has a constant mutation rate. the sequences of mitochondrial dna for the two species are shown below.
species a: gactgggcatta
species b: gaccggacatga
using the principles of molecular clocks and a known mutation rate for this sequence, the scientists determine that these species diverged from a common ancestor 30 million years ago. based on this information, how much longer do you predict it would take these species to differ by a total of seven base pairs?
60 million years
20 million years
140 million years
40 million years

You are given an electron micrograph of a bacterial cell. in the micrograph you can clearly see three thin layers of different densities surrounding the cell. based on the micrograph, you can infer that this cell is and would appear after application of the gram stain procedure. gram-negative / pink gram-positive / purple gram-positive / pink gram-negative / purple
