  • B2
    • the distribution of organisms
      • have a larger sample size = more reliable
      • invalid data could be because the data doesn't relate to the question
    • enzymes
      • substrate fits into enzyme and enzyme breaks it into smaller pieces
      • emulsification in digestion = breaks fat into smaller droplets, larger surface area for lipase to work on = faster
      • advantages of enzymes in industry
        • work for a long time, faster = less electricity
    • animals and plants use energy for: to build proteins, build larger molecules, allow muscles to contract, maintain body temperature
    • DNA
      • national genetic database
        • crime scene matched straight away
        • invasion of privacy
