The exact match in amino acid sequences of proteins found in closely related species is an example of how comparisons of ______ can indicate evolutionary relationships.Multiple choice question.developmentanatomybiogeographyproteins

Two species diverged from a common ancestor 2 mya based on fossil evidence. There are 10 amino acid differences in their hemoglobin molecules. We are interested in when 2 other related species diverged from a common ancestor. We don’t have any fossil evidence to help us but we do know that the 2 species have 20 amino acids different between them. According to the molecular clock, how many mya did these 2 species have a common ancestor?Group of answer choices1mya2 mya4 mya8 mya

How many different AMINO ACIDS are there that all living organisms use?Group of answer choices1220344664
