Rebekah is studying a molecule and trying to determine if it is dna or rna. which kind of molecule is she studying?

a-carbohydrate
b-protein
c-nucleic acid
d-lipid

Ans. (C).nucleic acid.

Nucleic acids are complex organic biomolecules, which are found in all living organisms. They are made up of nucleotides and are of two types, DNA and RNA.

The DNA molecules are made up of deoxyribose sugar (which lacks 2'-OH group), phosphate molecule, and nitrogen bases (cytosine, thymine, guanine, and adenine). On the other hand, RNA molecules are made up of ribose sugar (having 2'-OH group), phosphate molecule, and nitrogen bases (cytosine, uracil, guanine, and adenine).

So, Rebekah is studying the nucleic acid molecule that can be either DNA or RNA.

Thus, the correct answer is option (C).

d. making up measurements to record.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
