For question number four, the total dilution will be 10 raised to the power of negative 7.
00:07
Because from the previous dilution, we have 10 raised to the power of negative 6.
00:13
And basically here, in this part, we have the total evolution or dilution, which is negative 7.
00:21
So there is 10 raised to the part of negative 1 added.
00:25
For number 5, the total 6 delusions will be total 6 deletions when we dilute the original sample for the first time, and we will get 10 raised to the power of negative 1 deletion.
00:40
Similarly, when we serially dilute the sample 6 times, and we will get 10 raised to the part of negative 6 dilution.
00:49
If there were 128 ,000 cells in the original bacteria culture, then after each dilution, count of the cell reduced to 1 over 10th fold.
01:06
Hence, the very next deletion will give 128 ,000 cells.
01:12
Similarly, successive three deletions of 128 ,000 cells will give 128 ,000 cells.
01:21
Which lies between to 30 to 300 cells and each 128 cells will form their own colony forming unit.

For number 8, for number 7 rather...
