Microbiologists debate the use of biochemical similarities and cell features as a way of determining the taxonomic relationships among prokaryotes. Explain why some microbiologists believe these similarities and differences are a powerful taxonomic indicator, whereas others think they are not very useful for that purpose.

- Many of the first prokaryotes to be cultured in a scientific lab were human or animal pathogens. Why would these species he more readily cultured than non-pathogenic prokaryotes? Pathogenic prokaryotes are hardier than non-pathogenic prokaryotes Non-pathogenic prokaryotes require more supplements in their growth media Most of the necessary culture conditions could be inferred for pathogenic prokaryotes Pathogenic bacteria can grow as free bacteria, but non-pathogenic bacteria only grow as parts of large colonies.arrow_forwardhelping tags: biology, prokaryotes, cell membrane Describe the function/s of the intracytoplasmic membrane found in the following prokaryotes.. a) Nitrogen-fixing organism named Azotobacter vinelandii b) Purple non-sulfur bacteria (PNSB) ** Will UPVOTE, just pls help me answer the questions.
