- 2What is the end product of anaerobic respiration in yeast?
- 3Name the functional unit of the kidney.
- 4Which part of the brain controls balance and coordination of movement?
- 5What is the phenotypic ratio in the F₂ generation of a monohybrid cross?
- 6What percentage of energy is transferred from one trophic level to the next?
Section II — 4 × 2 marks = 8 M
- 1Define photosynthesis. Write the balanced chemical equation for photosynthesis.
- 2What is a reflex action? Give two examples of reflex actions in humans.
- 3Explain sex determination in humans. Who is responsible for the sex of the child?
- 4What is biodegradable waste? Give two examples each of biodegradable and non-biodegradable waste.
Section III — 5 × 4 marks = 20 M (internal choice in one question)
- 1Draw a neat labelled diagram of the human heart. Explain double circulation — pulmonary and systemic circuits. Why is double circulation necessary in humans?
- 2Describe the structure of a nephron with a labelled diagram. Explain the three processes involved in urine formation.
- 3What are plant hormones? Describe the role of auxin in phototropism with a diagram. Name two other plant hormones and state one function of each.
- 4State Mendel's Law of Segregation. Show a monohybrid cross between a tall (TT) and dwarf (tt) pea plant. What is the ratio in F₁ and F₂ generations? Explain the terms genotype and phenotype.
- 5What is a food chain? Draw a food chain with 4 trophic levels from a grassland ecosystem. Explain the 10% energy law. What is biomagnification?
Section IV — 2 × 8 marks = 16 M (internal choice for each)
- 1Describe the human nervous system with a neat labelled diagram. Explain the structure of a neuron and how a nerve impulse is transmitted. What is a reflex arc? Draw and label the reflex arc.
- 2Explain the process of reproduction in flowering plants. Include pollination, fertilisation, and seed formation. Draw a labelled longitudinal section of a flower. What is the difference between self-pollination and cross-pollination?
