Standards to be taught in Biology 1 CP and H
B-LS1 From Molecules to Organisms: Structures and Processes
B-LS1-4. Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing, and maintaining complex organisms. (Resembles H.B.2D.1)
B-LS1-5 Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy. (Resembles H.B.3A.2, but emphasis is on inputs and outputs, not biochemical steps)
B-LS1-6. Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and other large carbon-based molecules necessary for essential life processes. (Resembles H.B.3A.3, but different SEP)
B-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules are broken and the bonds in new compounds are formed, resulting in a net transfer of energy. (Resembles H.B.3A.4, but does not include fermentation and the focus is more on overall input and output.
B-LS2 - Ecosystems: Interactions, Energy, and Dynamics
B-LS2-1. Use mathematical and/or computational representations to support explanations of biotic and abiotic factors that affect carrying capacity of ecosystems at different scales. (Resembles H.B.6A.1- see clarification statement)
B-LS2-4. Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. (Resembles H.B.6B.2)
B-LS2-5. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere. (Resembles H.B.6B.1)
B-LS2-7. #Design, evaluate, and refine a solution for reducing the impacts of human activities on biodiversity and ecosystem health. (Resembles H.B.6D.1)
B-LS4 - Biological Evolution: Unity and Diversity
B-LS4-2. Construct an explanation based on evidence that the process of evolution primarily results from four factors:
(1) the potential for a species to increase in number (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction (3) competition for limited resources (4) the proliferation of those organisms that are better able to survive and reproduce in the environment. (Related to H.B.4D.1 and H.B.5B.1)
B-LS4-4. Construct an explanation based on evidence for how natural selection leads to adaptation of populations. (Resembles H.B.5A.2 and H.B.5C.1, but different SEPs)
B-LS4-5. Evaluate the evidence supporting claims that changes in environmental conditions may result in (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. (Resembles H.B.5B.2, can also relate to H.B.5C.3)
