The exam paper evaluates biological concepts and processes in the context of evolution, human physiology, ecosystems, and molecular biology. Topics include natural selection, evidence for evolution, the endocrine system, glucose metabolism, photosynthesis, food chains, and conservation. It covers genetic inheritance, DNA structure, decay processes, the impact of human activities on biodiversity, and thermoregulation. Practical applications focus on data analysis, experimental design, and biological implications of human and environmental interactions. Keywords: evolution, natural selection, endocrine system, glucose metabolism, photosynthesis, biodiversity, DNA, genetic inheritance, thermoregulation, conservation, experimental design.
