Summary

• Description:

  The PDF document comprises STAREHE GIRLS' CENTRE Biology Paper 2 Pre Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a Pre-mock Biology Paper 2 (Theory) examination.

  This paper tests in-depth theoretical analysis, physiological experiments, Mendelian genetics, population ecology, and organ system adaptations. It challenges candidates to integrate conceptual knowledge with data analysis and scientific reasoning.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 8 (Questions 1 - 8)
  • Structure: Section A (40 marks) containing 5 compulsory structured questions (questions 1 to 5, 8 marks each); Section B (40 marks) containing a compulsory data/graph interpretation question (question 6, 20 marks) and two essay choices (questions 7 and 8, 20 marks each) where candidates answer either one.

  It covers the following topics:

  • Section A:
    • Enzyme kinetics (effect of temperature on enzyme reactions and denaturing)
    • Genetics and inheritance (sex linkage, colour blindness pedigrees, monohybrid crosses, and terminology)
    • Sensory reception and plant responses (mechanoreception in the human ear, brain meninges, and plant tropisms)
    • Plant anatomy and water transport (longitudinal section of young root, root hair cells, cortex, and xylem vessels)
    • Cell physiology (osmosis, water potential demonstrations using semi-permeable membranes, tonicity, and haemolysis)
  • Section B:
    • Population ecology and demographics (graph plotting of mice population dynamics, litter calculations, and environmental carrying capacity)
    • Mammalian anatomy and thermoregulation (structural adaptations of mammalian skin to its functions)
    • Endocrine control and human reproduction (hormonal regulation of the human female menstrual cycle)
