Answer:

All of the following modifications to the study are likely to allow identification of new variants associated with the disease, EXCEPT

a. increasing the size of your cohorts.

Explanation:

Option A is chosen because increasing the size of the cohorts will be equally divided between the affected and unaffected cohorts since the study discovered that these two classes are roughly the same size.  Therefore, new variants of the disease may not likely be identified and isolated unless the other modification options are followed instead of Option A.

If we have a plate that has 2500 colonies on it, can we use this plate to calculate CFU's
AleksAgata [21]

No, the solution with bacteria in it needs to be diluted in order to be in the range of 30 – 300.

A colony-forming unit –CFU is used to estimate the number of viable (ability to divide by binary fission) microbes in a sample.  

A sample of microbes is diluted and spread on a plate. Then, the number of colonies is counted, assuming that each colony have grown from a single colony-forming unit, or CFU.

Plates with more than 300 colonies are difficult to count while those with less than 30 colonies give statistically unreliable numbers of colonies to count.
