Document Summary

Protista: kingdom including several groups of unicellular eukaryotes. The domain is added and becomes the highest group. First organisms to arise were heterotrophs feeding off the nutrients in the primordial soup. The descendent of all of the various groups. Archaea are more complicated unicellular organisms than bacteria. For example, they have histone proteins as well as complex rna polymerases contrarily to the bacteria. The diversity within the bacteria prevents us from classifying bacteria morphologically. Just using morphological traits, you get no predictor about what the potential of the bacteria is. A certain strain of e. coli is known as o157h7. These numbers represent the proteins found in the cell wall and in the flagellum. In other words, there are 157 variants of proteins in the cell wall and 7 in the flagellum. This kind of diversity shows the range in their toxicity from being beneficial to harmful.
