Scientists compare DNA from living organisms to identify similarities between species

Answer: Option D

<u>Explanation:</u>

The DNA content of any organism codes for its behavior and other activities, the nucleic acid is the only encryption that takes the internal code of the parents to the off springs, hence a comparison in the evolution can be done only through testing the DNA content.

The information in the DNA also tells us the evolution of species along with their relationship with each other. Thus helps in the construction of the phylogenetic tree.

Which of the following are common traits of chloroplasts and mitochondria?
Delvig [45]

Answer:

c. Both have their own DNA.

Explanation:

Both chloroplast and mitochondria are semi-autonomous organelles which means that they both have their own DNA. Both of these organelles have a circular DNA and make some of their own proteins by themselves. Both are double membrane-bound organelles. Chloroplast has a third membrane system called thylakoid.

Chloroplasts are found in the plant cells only as they are the site for photosynthesis. Mitochondria are present in both plant and animal cells and are the site for cellular respiration to produce energy to support the vital functions of cells.

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.
