Answer:
C. Heredity
Step-by-step explanation:
Homeostasis means that an organism can control its own body temperature. This is important because if we couldn't control our temperature, then our cells would have trouble working properly from being to hot or cold.
Cell organization means that our body and cells can organize themselves into groups that work together. For example, cells form groups and tissue for different organs while other cells form nerves.
Heredity is the passing of genes from parent to offspring
