| C3a* All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment. | NOT PRESENT IN CA STATE STANDARDS | NOT PRESENT IN SFUSD STANDARDS |
| C3b* Regulation of an organism's internal environment involves sensing the internal environment and changing physiological activities to keep conditions within the range required to survive. | NOT PRESENT IN CA STATE STANDARDS | NOT PRESENT IN SFUSD STANDARDS |
| C3c* Behavior is one kind of response an organism can make to an internal or environmental stimulus. A behavioral response requires coordination and communication at many levels, including cells, organ systems, and whole organisms. Behavioral response is a set of actions determined in part by heredity and in part from experience. | NOT PRESENT IN CA STATE STANDARDS | NOT PRESENT IN SFUSD STANDARDS |
| C3d* An organism's behavior evolves through adaptation to its environment. How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history. | NOT PRESENT IN CA STATE STANDARDS | NOT PRESENT IN SFUSD STANDARDS |
