Revision checklist
  • Adaptations
  • Competition
  • Farming methods
  • TB in cattle
  • Indicator species
  • Food webs and chains
  • Chemicals in the food chain
  • Fertilisers – nitrates build up in water = animals suffocate
  • Pyramids of biomass and number
  • Carbon cycle
  • Nitrogen cycle
  • Genes, DNA, alleles
  • Genetic profiling
  • Sex chromosomes
  • Punnett squares and key words
  • Dominant and recessive
  • Variation and Gregor Mendel
  • Genetic modification (GM)
  • Gene therapy (cystic fibrosis)
  • Variation (continuous and discontinuous)
  • Mutations
  • Evolution
  • Natural selection (e.g. In rats and bacteria)

  • Control of body temperature
  • Control of blood glucose levels
  • Plant responses (gravitropism, phototropism)
  • Diagram of skin
  • Health:
  • Drugs
  • Alcohol
  • Smoking
  • Food groups
  • Drug testing
qwc questions
QWC questions
  • How did “......................” develop this characteristic over time =
  • How do nitrates affect aquatic animals?
  • Temperature regulation
    • Sweating
    • Hairs / feathers
    • Blood vessels

How would you investigate the amount of energy in different foods?
