1 Active Transport

2 Active Transport

3 Exchange in the Lungs

4 Alveoli Alveoli have thin walls, a large surface area and a rich blood supply

5 Exchange in the Gut As the concentration increases in the small intestines active transport will occur to ensure no food is wasted.

6 The gills have a large surface area, thin walls and a rich blood supply

7 Simple diagram of inside a leaf

8 Stomata open and closed

16 Aerobic Respiration

17 Anaerobic Respiration

18 The Kidney

19 The blood is filtered and all the sugar is reabsorbed. Mineral ions and water needed are selectively reabsorbed. The mineral ions, water and urea are removed in the urine The sugar is reabsorbed by active transport

20 Dialysis -If a kidney is damaged or failing dialysis can be carried out. -The dialysis fluid contains the same concentration of glucose and mineral ions as the blood. -The dialysis fluid contains no urea. -It is a time consuming process -Must have a controlled diet

21 Transplant -A donor is required -The donor kidney maybe rejected -Must take immunosuppressants drugs for the rest of their life -Can have a normal diet

22 Bacteria

30 The product made is used as a fuel A slurry is produced that is used as a fertiliser The production of methane is an exothermic reaction

31 The generators can be built above ground or underground. Initial costs are more to build Harder to repair Cheaper long term as it keeps heat in Have to be trained to use it Cheaper to build Easier to repair Costs more long term as more heat is radiated Have to be trained to use it

32 More Biogas Sugar cane and maize is fermented anaerobically to produce ethanol. It is distilled. It is a carbon neutral fuel.
