Learning Objectives:

2.10 Use representations and models to pose scientific questions about the properties of cell membranes and selective permeability based on molecular structure.
2.11 Construct models that connect the movement of molecules across membranes with membrane structure and function.
2.12 Use representations and models to analyze situations or solve problems qualitatively and quantitatively to investigate whether dynamic homeostasis is maintained by the active meovement of molecules across membranes.
3.31 Describe basic chemical processes for cell communication shared across evolutionary lines of descent.
3.32 Generate scientific questions involving cell communication as it relates to the process of evolution.
3.33 Use represntations and appropriate models to describe features of a cell-signaling pathway.
3.34 Construct explanations of cell communication through cell-to-cell direct contact or through chemical signaling.
3.35 Create representations that dpict how cell-to-cell communication occurs by direct contact or from a distance through chemical signaling.
3.36 Describe a model that expresses the key elements of signal transduction pathways by which a signal is converted to a cellular response.
3.37 Justify claims based on scientific evidence that changes in signal transduction pathways can alter cellular response.
