    2.A.3: Organisms must exchange matter with the environment to grow, reproduce and maintain organization.

     

    Enduring understanding 2.B: Growth, reproduction and dynamic homeostasis require that cells create and maintain internal environments that are different from their external environments.

    Essential knowledge:

    2.B.1: Cell membranes are selectively permeable due to their structure.

    2.B.2: Growth and dynamic homeostasis are maintained by the constant movement of molecules across membranes.

    2.C.2: Organisms respond to changes in their external environments.

     

    Enduring understanding 2.D: Growth and dynamic homeostasis of a biological system are influenced by changes in the system’s environment.

    Essential knowledge:

    2.D.1: All biological systems from cells and organisms to populations, communities and ecosystems are affected by complex biotic and abiotic interactions involving exchange of matter and free energy.

    2.D.2: Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation in different environments.

    2.D.3: Biological systems are affected by disruptions to their dynamic homeostasis.

    2.D.4: Plants and animals have a variety of chemical defenses against infections that affect dynamic homeostasis.

     

    Enduring understanding 2.E: Many biological processes involved in growth, reproduction and dynamic homeostasis include temporal regulation and coordination.

    Essential knowledge:

    2.E.1: Timing and coordination of specific events are necessary for the normal development of an organism, and these events are regulated by a variety of mechanisms.

    2.E.2: Timing and coordination of physiological events are regulated by multiple mechanisms.

    2.E.3: Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection.

    Enduring understanding 3.A: Heritable information provides for continuity of life.

    Essential knowledge:

    3.A.1: DNA, and in some cases RNA, is the primary source of heritable information.

    3.A.2: In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.
