adhesion, cohesion, and transcription
cohesion, adhesion, and transpiration
cohesion, hybridization, and transpiration

How do organisms manage to grow, reproduce, and maintain their internal organization?
Organisms are consumers and obtain their energy and raw material from other organisms
Organisms exchange matter with the environment, taking in nutrients and releasing waste products
Organisms are producers, taking in raw materials and forming their organic compounds utilizing energy from the sun
Organisms recycle already exsisting raw materials thereby providing a constant stream of organic compounds
