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.
<span>Hemostasis is the process of the body that seals blood vessels that rupture. The process is basically starts with an injury, then vascular spasm, platelet plug formation and then coagulation.
During blood clot formation, blood is transformed into solid gel at site of damage, where plasma fibrinogen is converted into loose fibrin molecules, which bind together to form mesh. Platelets and blood cells get trapped here by the fibrin strands, which produces a clot. This part of the clot formation is called coagulation.

Answer:
involuntary muscle
Explanation:
Involuntary muscles are those that cannot be controlled by will or consciousness and are frequently associated with organs that contract and relax slowly and regularly. Because there are no striations when viewed under a microscope, involuntary muscles are also known as smooth muscles or non-striated muscles.
