Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

What is DNA molecule?</h3>
- Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
- Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
- An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
- To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.

Answer:
<em>The correct option is b. the model is insufficiently labeled</em>
Explanation:
Models showing certain cycles should clearly show the reactants and the products being formed. They should be able to depict the various changes in the reactants which lead to the formation of the products.
The diagram shown in the picture is a poor depiction for the process of photosynthesis as well as cellular respiration. I does not tell us the products being formed. Like oxygen gas is released during photosynthesis but it is just labelled as gas in the diagram. The sugar being formed is also not named which is glucose.
Function. There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption ofnutrients in the lumen. There are alsoenzymes (enterocyte digestive enzyme) on the surface for digestion.
