[B-LS1-6] Organic Compounds2 - Skill/Concept

Which of the following statements best explains how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and other large carbon-based molecules?

• • Carbon, hydrogen, and oxygen can form bonds with other atoms, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen can form a mixture, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen can change phases from gas to liquid, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen cannot form bonds with other atoms, and therefore cannot combine into larger molecules.
