Nucleic acids are polymers of nucleotides. The monomers of nucleic acids consist of a phosphate group, a five-carbon sugar, and a nitrogenous base.
<h3>Nucleotides and DNA</h3>
DNA (deoxyribonucleic acid) provides directions for its own replication.
A gene provides the directions to build a molecule of RNA.
A polynucleotide has a repeating sugar-phosphate backbone.
The structure of DNA is a double helix molecule, whereas RNA usually consists of a single polynucleotide strand.

B.
Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
Answer:
Moves water from root to the rest of the plants.
Explanation:
The structure labeled X is xylem.
Xylem is a vascular tissue found in vascular plants that is responsible for transporting water from the roots to other parts of the plant. It also provide mechanical support and storage.
