Question

this is a macromolecule that holds cell information in a coded form. made of sugar, phosphate and nitrogen - containing bases.
a macromolecule made up of mainly carbon and hydrogen atoms that is primarily used for energy storage and in cell membranes.
a macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair.
this is the repeating structural unit that forms rna and dna.
this is a molecule with a large molecular mass. many examples come from biology and in particular biochemistry.
macromolecule protein lipid nuclea

Explanation:

1. The first description matches nucleic acids (DNA and RNA) which are made of sugar, phosphate and nitrogen - containing bases and hold cell information.
2. The second description is of lipids which are made of carbon and hydrogen and used for energy storage and in cell membranes.
3. The third description is of proteins which contain carbon, hydrogen, oxygen and nitrogen and are used for growth and repair.
4. The repeating structural unit of RNA and DNA is a nucleotide.
5. The general description of a large - molecular - mass molecule from biology is a macromolecule.

Answer:

1. Nucleic acid
2. Lipid
3. Protein
4. Nucleotide
5. Macromolecule
