All eukaryotes have an associated microbiome, often including mutualistic associations that are critical for normal function. Why are these associations so common in eukaryotes? Be sure to include your answers to question 2 in your explanation. 4. (0.5 pts) The species compositions of microbiomes are analyzed using sequence data. Why can't scientists use morphology for this purpose? List two problems with using morphology for phylogenetic analysis of bacteria and archaea: 1) 2) 5. (0.5 pts) While DNA sequences are the preferred data type for building trees of bacteria and archaea, there are some potential challenges. Use what you learned at station D to explain how sequence data might produce misleading trees.
