  It covers the following topics:

  • Cell physiology (haemolysis and reversing plasmolysis)
  • Classification (kingdom characteristics like prokaryotic nature and cellulose cell walls)
  • Nutrition in plants (roles of light in photosynthesis)
  • Nutrition in animals (enzymes, roles of stomach muscles, dentition of herbivores vs. carnivores, and roles of the tongue)
  • Cell division (meiosis, synapsis, and crossing over)
  • Transport in animals (transport forms of carbon (IV) oxide and blood group compatibility)
  • Reproduction in plants (role of gibberellin in germination, double fertilization, post-fertilization changes, and floral adaptations for wind pollination)
  • Microscopy (calculating magnification from field of view)
  • Ecology (identification of ecological instruments and the capture-recapture method for estimating populations)
  • Respiration (investigating physiological processes using a soda lime setup)
  • Plant physiology (factors affecting the rate of transpiration such as humidity and leaf surface area)
  • Biochemistry (properties of lipids, essential nutrients for impulse transmission/haemoglobin, and energy sources during varying exercise intensities)
  • Evolution (homologous structures)
  • Genetics (heterozygous vs. homozygous genotypes, and sex-linked inheritance of haemophilia)
  • Economic importance of plant products (colchicine and quinine)
