If you compared two motile bacterial species and determined one was considerably more motile than the other, which arrangement of flagella would you expect to be associated with the highly motile species? How would you confirm this?

How long would it take a single bacterial cell to form 1,000,000 cells if it had a generation time of 30 minutes?

"a long, thin cellular appendage present in many Archaea that rotates and is responsible for swimming motility" Name it.

Comparing the different methods for counting bacterial cells, which of the following is FALSE? A. The serial dilution methods counts only viable cells.  B. The turbidity method indirectly measures the number of cells observing how much light goes through a broth sample  C. The turbidity method uses a spectrophotometer  D. The direct microscopic method counts only viable cells  E. The direct microscopic method counts both viable and non-viable cells

In the experiments below, different prokaryotic cells were grown in broth cultures in the presence or absence of an antibiotic (either vancomycin or polymixin) After 1 hour, cells were rinsed, and the percent of bacteria that survived was determined. According to the data, which experiment (A or B) was done with vancomycin and which was done with polymyxin? Explain your reasoning in both cases. 100 0 A Bacillus E. coli with antibiotic without antibiotic B Methanoge n 100 Bacillus E. coli Methanogen
