  14. Each student gets:

  15. Student Report

  16. Sample Food Test Practical question

  17. (a) For each food substance identified in 1(a);

  18. NECTA Practical Past Papers

  19. 2012 - BIOLOGY 2A (ACTUAL PRACTICAL A) 1. You have been provided with specimens F and G.

  20. 2. You have been provided with specimens H, I, J andK. a. Study carefully specimens H and I then:

  21. 2011 - BIOLOGY 2A (ACTUAL PRACTICAL A) 1. The solution prepared contained various food substances.

  22. a. State the function in the human body of each food identified in 1(a) above. b. Name two enzymes necessary for digestion of food substance(s) identified in (a) above. c. To each type of food identified above, name at least one source in which the food has been extracted. 2. Study specimen A, B and C then:

  23. 2010 - BIOLOGY 2A (ALTERNATIVE A PRACTICAL)

  24. b. What are the functions of the food substances identified in T1 in the human body? c. i. State the favorable/suitable pH condition at which the enzymes which digest the food substances present in T1 work best. ii. Which of the food substances present in T1 is not stored in the human body? iii. What happens when the levels of this substance mentioned in (c) (ii) above, rises in the body?

  25. Classification

  26. Where to Find Specimens

  27. Storage of Specimens

  28. Sample Classification Practical

  29. 1. Sample Practical Solutions

  30. 2. Classifaction by kingdom and phylum

  31. 3. Further classification:

  32. 4. Specimen P (moss) cannot grow taller because it has no xylem and phloem. If it grew taller, it would not be able to transport food and water throughout the plant. 5. Characteristics of phylum Arthropoda:

  33. 6. Specimen M (bean plant) reproduces by sexual reproduction. Specimen N (yeast) reproduces by asexual reproduction.
