Explore life from molecules to organisms through an integrated survey of human biology. Build fluency with the scientific method, controls, and basic data interpretation. Examine chemistry of life, water and pH, and the structure–function roles of biomolecules. Investigate cell structure, membranes, transport, and cellular energetics. Connect DNA, gene expression, meiosis, and inheritance to human variation and evolution. Understand tissues, homeostasis, and coordination via neural and endocrine signaling. Survey major organ systems with health links, immunity, reproduction, and development. Apply core physics and chemistry—pressure/flow, diffusion, gradients, surface area, energy, and acid–base—to interpret simple clinical measures.
