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.
<span>Flatworms use a system of canals and tubes with the mouth as their excretory organ. They belong to the Phylum Platyheminthes. </span><span>Flatworms
can be cut in half creating two individuals by binary fission. Binary
fission is a type of asexual reproduction in which the offspring has the same
features and characteristics of the parent. During binary fission, the DNA
replicates into two and goes at the end of each membrane. And then the cell
membrane divides into two daughter cells. Then cytokinesis follow.</span>
The answer choices are not provided, so I cannot select the correct one. However, I may provide you examples and guidance on how to choose the correct one.
As mentioned in the explanation, a scientific question must have a variable that is changed, the independent variable, and a variable on which the effect of the change is measured. This is the dependent variable. Examples of such questions include:
How will the amount of water given to a plant affect its rate of growth?
What will be the amount of sugar that can be dissolved in water at a given temperature?
At what temperature will a balloon filled with air pop?
All of these questions may be tested using experiments.
I’m not sure but it looks like a new born..probably 1 month old.
Proteins, among the most complex of all organic compounds, are composed of amino acids (see Figure 2-4), which contain carbon, hydrogen, oxygen, and nitrogen atoms. Certain amino acids also have sulfur atoms, phosphorus, or other trace elements such as iron or copper.
