Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed.
uranmaximum [27]

A law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.

<h3>What exactly is a hypothesis?</h3>

A hypothesis is a guess based on a large amount of background information. If only five trees survived, they may have received more light than the other five.

In that case, one will devise an experiment in which the same plant is randomly assigned to different treatment groups with varying degrees of light, and the rate of growth of each group is compared.

Thus, a law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
