Next-generation sequencing reveals six new mutations have occurred in the coding regions of genes in an individual diploid fly. if the coding regions of this fly comprise 100 million nucleotides per haploid genome, what is the mutation rate per nucleotide?

Paleontologists have found plant fossils deep within the layers of the north polar region. these leaf fossils have been labeled as to the rock layers they were found in, with the lower numbers being layers close to the earth's surface and higher numbers representing deeper layers. according to the numbers of these four leaf fossils, what might you infer?
