The exam paper covers core A-level biology topics, including physiological processes (e.g., heart rate regulation, enzyme activity), molecular biology (e.g., gene expression, RT-PCR), ecology (e.g., species interactions, biodiversity), genetics (e.g., inheritance, Hardy-Weinberg principle), and applied biology (e.g., disease control, biotechnology). It integrates experimental analysis, critical thinking, and problem-solving, emphasizing data interpretation, hypothesis evaluation, and calculation of biological parameters (e.g., biomass, population estimation). Keywords include “photosynthesis,“ “Krebs cycle,“ “muscle fibers,“ “sympatric speciation,“ “Alzheimer′s disease,“ “transgenic organisms,“ and “gene mutations.“
