The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.
Based on the tabular data, and assuming that time advances vertically, which phylogenetic tree is the most likely depiction of the evolutionary relationships among these five species?

A researcher studying bacterial toxin predicts that a lysine within the toxin is important for binding it’s target cell. She used site-directed mutagenesis to change a codon for lysine (AAA) to one for asparagine (AAU). However, the mutant toxin still binds to its target cell just as well as the wild-type toxin bound and appears to have no other changes. This type of mutation is probably

If the equilibrium constant, Keq, for the reaction ATP → ADP + Pi is 2.22 × 105 M, calculate the standard free-energy change, ΔG°, for the synthesis of ATP from ADP and Pi at 25 °C.
