Nucleotides are the building blocks of nucleic acids. In DNA, there are four types of nucleotides each containing one of four nitrogenous bases: guanine (G), cytosine (C), adenine (A), thymine (T).
- The monomer exhibited in the figure is a NUCLEOTIDE, i.e., a purine (Adenine) nucleotide.
- A nucleotide is a molecule composed of a nitrogenous base, a pentose sugar (deoxyribose in DNA) and a phosphate group.
- Purine bases consist of a double‐ring structure having four nitrogen (N) atoms and five carbons (C) atoms.

The correct answer is letter A: the circulatory system removes waste from the tissues by converting carbon dioxide-rich blood into oxygen-rich blood that can be circulated throughout the body to support its several functions. Without the lungs the human body will not be able to process converting blood cells into oxygen-rich cells in the body.
Protects brain and spinal cord from trauma, as well as supplies nutrients to nervous system tissue. It also removes waste from cerebral metabolism.
ATP is adenosine triphosphate, it is like a fully charged battery in a cell, ADP is basically ATP that has been drained of its energy from a chemical reaction. It is like a dead battery that can be recharged later ;)
