1. responsible for \waterproofing\ molecules
2. examples include oils, waxes, and butters
3. responsible for coding for proteins
4. comprised of nucleotides
5. comprised of saccharides or sugars
6. composed of amino acids
7. serve as enzymes that speed up cellular processes
8. polymers of amino acids
9. dna and rna are examples of this macromolecule.
10. breads, pastas, fruits and sweets are examples.
11. made of carbon, hydrogen and oxygen
12. include triglycerides and phospholipids

check your understanding
answer the following questions:

Explanation:

1. Lipids are hydrophobic and can act as waterproofing molecules.
2. Oils, waxes, and butters are all types of lipids.
3. Nucleic acids (DNA) code for proteins.
4. Nucleic acids (DNA and RNA) are made of nucleotides.
5. Carbohydrates are made of saccharides or sugars.
6. Proteins are composed of amino acids.
7. Enzymes (which are proteins) speed up cellular processes.
8. Proteins are polymers of amino acids.
9. DNA and RNA are nucleic acids.
10. Breads, pastas, fruits, and sweets are high in carbohydrates.
11. Carbohydrates, lipids, and proteins are made of carbon, hydrogen, and oxygen (nucleic acids also have nitrogen and phosphorus).
12. Triglycerides and phospholipids are types of lipids.
