What information can a phylogenetic tree tell you? correct answer: a visual representation of the relationship between different organisms, showing the path through evolutionary time from a common ancestor to different descendants. What is the basis for similarity differences between amino acid correct answer: All amino acids have the same basic structure, At the "center" of each amino acid is a carbon called the α carbon and attached to it are four groups - a hydrogen, an α- carboxyl group, an α-amine group, and an R-group, sometimes referred to as a side chain. Given two similarity scores for two different subjects; what would cause you to think one of thesubjects diverged evolutionarily longer ago from the query sequence? correct answer: A higher similarity score would mean the subject is closer in similarity to the query sequence and therefore diverged longer ago.
