Performance expectationConstruct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements such as nitrogen, sulfur, and phosphorus to form amino acids and other carbon-based molecules.
Emphasis is on using evidence from models and simulations to support explanations for the synthesis of lipids, starches, proteins, and nucleic acids.
Assessment does not include the details of the specific chemical reactions or identification of structural and molecular formulas for macromolecules.
Every item written to HS-LS1-6 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
