Answer: that means that it has undergone the peer review process. Peer review is a process (not a type of article) in which an article is judged by an impartial panel of two or more experts in the field; these experts are called "peer reviewers.
Explanation:
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.

Explanation:
As I think last option is the correct suitable one.
We can use the formula D=m/v to determine the density of the ring.
With that, the correct answer would be A. 2 g/ml.
Hope I helped! :)
Overall, photosynthesis is a process that takes water, carbon dioxide, and sunlight, and converts it into oxygen and glucose.
The inputs of photosynthesis are light energy, and matter in the form of water absorbed through the roots, and carbon dioxide absorbed through the leaves. Photosynthesis also has matter and energy outputs.
