These are nucleotides that have a single ring structure. Example: Cytosine, Thymine, and Uracil
IgorLugansk [536]

Answer:

The question is incomplete.

However, I notice that your question is mainly dealing with

"Nucleotides with a single ring structure"

I tackled that part, also providing explanation to the point you focused on.

Explanation:

Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.

Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.

What is the term for a fruit that develops from tissues other than the ovary?
bekas [8.4K]

The correct answer is D. Accessory fruit

Explanation.

Fruits are structures that develop from the fertilized ovary of plants and that contain the seed of it, this includes simple, aggregate and multiple fruits. However, there is one type of fruits that do not develop from ovary but from other tissues that are usually near the ovary, these fruits are called accessory or pseudo fruits as they do not fit completely the definition of regular fruits, this includes fruits such as strawberries or pineapples that develop from tissues different to the ovary.
