Predict what would happen to the egg white if a raw egg were placed in vinegar
Whitepunk [10]

The vinegar contains acetic acid, so when the raw egg is dissolved in the vinegar, there will be an instant formation of bubbles as the raw egg’s shell will dissolve, as the contents of the insides of the egg will be rubbery and would be unable to be eaten or consumed.

You were instructed to compare growth on the na and columbia cna plates. why not simply compare the organisms to each other on t
Triss [41]

Answer:

Columbia CNA agar is a type of selective medium employed in culturing gram positive cocci and distincting it from clinical and nonclinical samples made up of a combined flora. Columbia CNA SHOULD NOT BE COMPARED with general culture medium such as the Nutrient agar which provides the necessary nutrients for the growth of diverse species of organisms.

Good growth stands for the growth of organisms picked or needed to culture with the required amount of colonies on Columbia CNA. Poor or no growth infers on the NA availability for the growth of the specimen organism, it is absent in the culture as it lacks the needed amount of colonies.

In conclusion, It may look good to look for the similarities and differences of the organisms to one another on the CNA plate since the NA plate is mainly the control and is used to evaluate the growth quality of the bacteria, contrasting it to the CNA plate is of no use as its main reason would be futile.
