Presentation Transcript

  1. 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)

  2. 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

  3. 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?
