  • Cell structure in unicellular organisms (identifying labelled parts and observable animal-like features)
  • Organic evolution (evidence of evolution; adaptation such as fur length differences)
  • Natural selection and survival (predation and colour variation in mice populations)
  • Endocrine system and reproduction (master gland; hormones controlling spermatogenesis and female reproductive cycle; effects of hormonal deficiency)
  • Genetics and inheritance (haemophilia pedigree analysis; genotypes, phenotypes, and sex-linked inheritance explanations)
  • Animal behaviour and responses (movement of larvae in light; naming the response and its survival value)
  • Plant growth responses (shoot curvature with agar blocks and explanation of growth response)
  • Environmental pollution (lead concentration data interpretation; sources, entry into blood, reduction measures, and effects on humans)
  • Ecology (eutrophication)
  • Transport in plants (significance of transpiration; forces moving water from roots to leaves)
  • Transport in mammals (oxygen transport in the body)
