DE.2. Materials and Their Properties
2.2. Mixtures and Solutions
Enduring Understanding: The properties of a mixture are based on the properties of its components.
2.2.E. In mixtures, individual components move from areas of higher concentration to areas of lower concentration to eliminate concentration differences. Diffusion is the movement of individual components. (Level: Compact)
DE.6. Life Processes
6.1. Structure/Function Relationship
Enduring Understanding: Living systems, from the organismic to the cellular level, demonstrate the complementary nature of structure and function.
6.1.D. The cell is the fundamental unit of life. Cells have basic needs for survival. They use energy, consume materials, require water, eliminate waste, and reproduce. (Level: Essential)
