B) The number of different amino acids between Hornworm moth and Silkworm moth is 2. This is a 4% difference in amino acid sequencing.

C) The number of different amino acids between Fruitfly and Silkworm moth is 5. This is a 10% difference in amino acid sequencing. #5. D) The number of different amino acids between Hornworm moth and Fruifly is 4. This is a 8% difference in amino acid sequencing. #7 E) The phylogenetic tree indicates that the difference in amino acid sequencing between the horse and donkey is 1% (0.1 + 0.9)

F) The phylogenetic tree indicates that the difference in amino acid sequencing between the dog and donkey is 8.5% (0.9 + 2.9 + 1.7 + 3.0)

G) The phylogenetic tree indicates that the difference in amino acid sequencing between the pig and dog is 6.0% (1.3 + 1.7 + 3.0)
