HS.Structure and Function

Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

Clarification Statement: Emphasis is on functions at the organism sy stem lev el such as nutrient uptake, w ater deliv ery , and organism movement in response to neural stimuli. A n example of an interacting sy stem could be an artery depending on the proper function of elastic tissue and smooth muscle to regulate and deliv er the proper amount of blood w ithin the circulatory sy stem.

A ssessment Boundary: A ssessment does not include interactions and functions at the molecular or chemical reaction lev el.
