  2. Question 1 • State the difference between an antigen and an antibody.

  3. Question 2 • Explain antibody production

  4. Question 3 • Explain how the skin and mucous membranes prevent entry of pathogens into the body.

  5. Question 4 • Explain why antibiotics are used to treat bacterial but not viral diseases.

  6. Question 5 • State one feature of alveoli that adapts them to gas exchange.

  7. Question 6 • The drawing below shows the structure of a virus. Identify the structure labeled I and II:

  8. Question 7 • Explain briefly why antibiotics are effective against bacteria but not viruses.

  9. Question 8 • Explain how antibiotic resistance develops in bacteria.

  10. Question 9 • The diagram below shows the male reproductive system. State the names of I and II.

  11. Question 10 • The umbilical cord connects the fetus to the mother during pregnancy. The following is a drawing of a cross section of an umbilical cord. Annotate the drawing above to show an artery. • Explain your choice.

  12. Question 11 • Draw an arrow to show where negative feedbacks occurs.

  13. Question 12 • Outline the organization of the human nervous system.

  14. Question 13 • Explain the significance of the principle of competitive exclusion.

  15. Question 14 • Ecologists sometimes measure the gross production and net production of a species in an ecosystem. • (a) Define the term gross production.

  16. Question 15 • (b) Explain why the gross production of a species in an ecosystem is always higher than the net production.

  17. Question 16 • (c) Outline the changes in the gross production of an ecosystem during ecological succession.

  18. Question 17 • Discuss the economic reasons for the conservation of tropical rainforest biodiversity.

  19. Question 18 • Simpson’s index is given by the following equation: • where: • D = the diversity index, N = the total number of all species found and n = the number of individuals of a particular species. • (i) State what would happen to this index if the numbers of one species increased but the total number of species stays the same.

  20. Question 19 • State what a high value of D suggests about an ecosystem.

  21. Question 20 • State the units that would be used if constructing a pyramid of energy.

  22. Question 21 • Explain how parasitism differs from mutualism, giving an example of each. • Distinguish between predation and parasitism.

  23. Question 22 • The total solar energy received by a grassland is 5 × l05 kJ m-2y-1. The net production of the grassland is 5 × 102 kJ m-2y-1. and its gross production is 6 × 102 kJ m-2y-1. The total energy passed on to primary consumers is 60 kJ m-2y-1. Only 10% of this energy is passed on to the secondary consumers. • (a) Calculate the energy lost by plant respiration. • (b) Construct a pyramid of energy for this grassland.

  24. Question 23 • Explain the low numbers of organisms in higher trophic levels of a food chain.

  25. Question 24 • State two factors that affect the distribution of animal species.

  26. Question 25 • Outline the process of ecological succession.

  27. Question 26

  28. Question 27 • Outline two uses of absorbed carbohydrates in humans.

  29. Question 28 • A pine forest has a net production of 52 kJ m–2 year–1. Respiration is 100 kJ m–2 year–1. Calculate the gross production.

  30. Question 29 • State two difficulties of classifying organisms into trophic levels.

  31. Question 30 • Explain how primary succession and secondary succession affect the abiotic environment.
