Biology

Science concepts--biological structures, functions, and processes. The student knows that biological structures at multiple levels of organization perform specific functions and processes that affect life. The student is expected to:

 Science concepts--biological structures, functions, and processes. The student knows the significance of matter cycling, energy flow, and enzymes in living organisms. The student is expected to:B.11

Science concepts--interdependence within environmental systems. The student knows that interactions at various levels of organization occur within an ecosystem to maintain stability.

relate the functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids, to the structure and function of a cell;

compare and contrast prokaryotic and eukaryotic cells, including their complexity, and compare and contrast scientific explanations for cellular complexity;

investigate homeostasis through the cellular transport of molecules;

compare the structures of viruses to cells and explain how viruses spread and cause disease.

explain how matter is conserved and energy is transferred during photosynthesis and cellular respiration using models, including the chemical equations for these processes;

investigate and explain the role of enzymes in facilitating cellular processes.

investigate and evaluate how ecological relationships, including predation, parasitism, commensalism, mutualism, and competition, influence ecosystem stability & explain the significance of the carbon and nitrogen cycles to ecosystem stability and analyze the consequences of disrupting these cycles;

analyze how ecosystem stability is affected by disruptions to the cycling of matter and flow of energy through trophic levels using models;

explain how environmental change, including change due to human activity, affects biodiversity and analyze how changes in biodiversity impact ecosystem stability
