If a bacterium has a generation time of 30 minutes, and you start with 100 cells at time 0, how many cells will you have in 30, 60, 90, and 120 minutes?

For the following sets of partial diploid bacteria, how do I fill out this table? I am not sure how to tell the difference between inducible and constitutive?

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

If you start with one bacterium (generation 0), how many bacteria would you have by generation 6 as a result of binary fission?  a) 8 b) 16 c) 32 d) 64

You sample cole slaw for bacteria soon after purchase, and after it has been left out on the kitchen counter for 6 hours (room temperature), and after 12 hours (at room temperature).    From the data below, CALCULATE  the generation time of the bacteria in this sample (at room temperature) – that is, the time it takes for the bacterial population to double in number. Soon after purchase:                                          4.0 x 103 bacteria per mlAt 6  hours at Room Temperature:                     1.9 x 105 bacteria per ml ( = 192 x 103 bacteria per ml)At 12 hours at Room Temperature:                    1.2 x 107 bacteria per ml  ( = 12,300 x 103 bacteria per ml)  What do you calculate the generation time to be?                                                 (generation time is the time needed for the population to double in size )                                  Hint:  What is double the initial population?                                                                Hint:…

Which of the following is not a method used to introduce foreign DNA into a bacterial cell? a) biolistic gun b) calcium chloride treatment followed by heat shock c) infection with a specific phage d) electroporation

In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 2,000, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 150.  Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium? There is no way to know given the information provided Both infections are equally likely Donoteatum thisbacterium Parasiticum mucoides

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

Can you say that the microbial composition changes over time in each of the body locations? Give two pieces of evidence. Why do you think the scientists also tested the soil around the cadaver? The study was done with mice and their cadavers decomposed on soil graves in the University of Colorado Transgenic Facility. Do you think the graphs would have looked different if the decomposition events would have happened outside during the hot summer months? Explain.

If a single 1.7 × 10−10 m3 bacterium could reproduce through cell division at a rate of 3(t − 0.5t), where t is measured in minutes, how much volume (in m3) will the resulting bacteria colony occupy after 1 hour?   bacteria colony volume = _____ × 104 m3
