Scientists аre studying three grоups оf prоkаryotes collected from different environments. DNA from the orgаnisms is compared with known organisms in the domains Bacteria and Archaea. Sample Environment DNA Similarity to Bacteria DNA Similarity to Archaea A Garden soil 94% 61% B High-salt lake 58% 96% C Human skin 91% 65% Using the data and concepts from Chapters 15–17, answer the following: A. Which sample is most likely an archaeon? Use two pieces of evidence from the data to support your answer.(2 points) B. If Samples A, B, and C were placed on a phylogenetic tree, which two samples would you predict would be more closely related? Explain your reasoning using the DNA evidence.(2 points) C. Sample B lives in a high-salt environment. Explain how this environmental information and the DNA evidence provide two different types of scientific evidence scientists can use to understand the organism.(2 points)
