Which of the following molecules is classified as inorganic?
What is a defining feature of an organic molecule found in a living organism?
- AIt contains hydrogen bonds.
- BIt cannot be broken down into smaller subunits.
- CIt contains carbon and hydrogen linked together.
- DIt does not contain hydrogen atoms.
What is a biological macromolecule?
- AA small organic molecule made up of one type of element
- BA large organic compound made up of smaller molecules
- CA large inorganic molecule made up of at least two different elements

Proteins, carbohydrates and nucleic acids are considered biological macromolecules. Which of the following best describes their basic structure?
- AThey are molecules of the same size (monomers) that are made up of repeating units (polymers).
- BThey are long or large molecules (polymers) that are made up of smaller subunits (monomers) joined together.
- CThey are small molecules (polymers) that are made up of smaller atoms (monomers) joined together.
What is a defining feature of an inorganic molecule found in a living organism?
- AIt is excreted as waste.
- BIt does not contain any carbon–hydrogen bonds.
- CIt contains chloride atoms.
- DIt cannot be broken down into smaller subunits.
