Document Summary
Higher difference in mean makes a higher t score. Figure out a hierarchy from data given. Plasmid loss: takes cells that are well adapted to one environment and put them in a new one. The resistant plasmid slow the growth, development and reproduction of the bacteria compared to non. The cell gets rid of the plasmid. Put the bacteria in a new flask repeatedly (after all of the nutrients are used up) Throughout the weeks, the cells begin to lose the plasmid. Do dilution to decrease the amount of cells so that when they"re plated on one plate w/ antibiotics and one without, you can tell the difference (count) Can"t plate more than 1/10 of ml. Plate for more than one tube so that the number isn"t too high or low. Calculate cumulative dilution by multiplying all singular dilutions in the set. Why did we transfer only 0. 1 ml to the plate.
