Final answer:
Carbon atoms in living things can form single, double, or triple bonds and can join together to form chains or rings. Additionally, carbon can bond with many other elements.
Step-by-step explanation:
All living things contain carbon. Carbon atoms have unique bonding properties, allowing them to form single, double, or triple bonds with other carbon atoms (i). They can also join together to form chains or rings (ii). Furthermore, carbon can bond with many other elements like hydrogen, oxygen, phosphorus, sulfur, and nitrogen (iii). These properties of carbon atoms allow for the diversity of molecules necessary for the forms and functions of living organisms.
