Revision checklist
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)


  • Negative feedback

  • 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?
