After observing your adherent cells in the T75 flask under the microscope, you estimate the confluence of the cells to be around 70%. When you passage the cells, you count the cells using a hemocytometer and obtain a total cell count of 6.5 x 10 cells. (T75 cell yield = 8.4 x 106 cells) 1. What does the cell count (from the hemocytometer) suggest is the % confluence of the flask? 2. Which number would you trust to be more...

please help with whatever possible. thank you so much in
advance.
Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

1) The approximate cell yield of a T25 flask (for adherent cells) is 2.8 x 106 cells. The cell yield is the total amount of adherent cells at confluence. How many adherent cells would you expect to be in this flask at 80% confluence? 2) For adherent cells, the seeding density is usually between what range of % confluencies? 3) How many total cells would you place in a T75 flask with a cell yield of 8.4 x 106 cells...
