We are increasingly understanding how an individual human being can be considered a walking ecosystem harboring an enormous diversity of microbes! If you were to analyze all the microbes in and on your body, you would be able to find representatives of which of the following types of organisms? Please choose the most complete (inclusive) answer.

You have performed an enrichment culture and successfully isolated a new species of bacteria from soils that consumes polyaromatic hydrocarbons, or PAHs. You confirm via a flagella stain that these bacteria possess flagella. If these bacteria are also capable of chemotaxis, and you placed a pipette full of a solution of PAHs into a container of your bacteria, you would predict ______.

You acquire a soil sample and run an enrichment culture on it using flasks that allow gas exchange with the air. You prepare a chemically defined media that contains all the macroelements required for growth except for nitrogen (i.e., no ammonia or proteins). What result do you expect to have at the end of your experiment?

Removing all the flagella from a bacterium would most likely ______.
