The answer is: All nucleotides have a phosphorus atom that can be replaced with 32P.
DNA building blocks are nucleotides. Nucleotides contain a nitrogenous base, a five-carbon sugar, and, at least, one phosphate group. Exactly that phosphate group in the nucleotide has the phosphorus atom. Therefore, the phosphorus atom in the nucleotide can be replaced with radioactive phosphorus-32 (32P). This replacement has a wide use in labeling nucleic acids and thereby visualizing the target molecule.

The strengths of the model the student created are it is clearly labeled and shows that oxygen and carbon dioxide is going in which direction.
A model is something that graphically describes any reaction or process. A model is made up of plastic or any solid material with colors. A model is a good way to show any process or work that has to be done at a big pace.
The model shows the movement of gas into and outside the body. The oxygenated blood transfer into the blood and the deoxygenated blood goes into the lungs.
Thus, the student's model has the advantage of being clearly labeled and showing which way oxygen and carbon dioxide are moving.

One strength of the model is that it clearly shows which gases are taken in and which gases are released for exhalation.
Answer: True
Explanation :
There are a large number of microorganisms that are present in the soil which plays an important role in making the soil rich in nutrients.
The degradation of the organic matter present in the soil is done by the action of several enzymes released by these microorganisms and hence, this leads to the release of several nutrients into the soil.
