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.
Earwigs, slugs, and snails eat annual flowers out of gardens.
<span>The student who use the hemoglobin data to conclude that mice and shrews are more closely related than mice and humans or shrew and human is quite correct. Scientists had found a way of determining the evolution histroy of animals by means of the amino acid sequence of their hemoglobin. The higher the number of related amino acids found the closer the relationship between the two organisms. There are a difference of 29 amino acid between man and mouse and a difference of 24 amino acids between human and shrew but only a difference of 5 amino acid between mouse and shrew. This shows that mouse and shrew are closer.</span>
