Section B - Short Answer (2 marks) — 16 marks
Answer all 8 questions, each carrying 2 marks.
Q1. Define nutrition. Name two types of nutrition. (2 marks)
Answer: Nutrition is the intake and utilization of nutrients. Types: Autotrophic (plants) and Heterotrophic (animals).
Q2. What is the difference between aerobic and anaerobic respiration? (2 marks)
Answer: Aerobic respiration uses oxygen; anaerobic respiration occurs without oxygen.
Q3. Describe the pathway of blood circulation in the body. (2 marks)
Answer: Heart -> Arteries -> Capillaries -> Veins -> Heart. Arteries carry oxygenated blood; veins carry deoxygenated blood.
Q4. What are the functions of the skeleton? (2 marks)
Answer: Support, protection of organs, movement, and mineral storage.
Q5. How do sound waves travel through different media? (2 marks)
Answer: Sound travels as longitudinal waves through solids, liquids, and gases. Speed varies in different media.
Q6. Define velocity and give an example with direction. (2 marks)
Answer: Velocity is speed in a given direction. Example: 60 km/h towards north.
Q7. What is friction? How does it affect motion? (2 marks)
Answer: Friction is a force opposing motion. It slows down moving objects and prevents motion.
Q8. Define work and give its SI unit. (2 marks)
Answer: Work is force multiplied by displacement. SI unit: Joule (J).
Section C - Long Answer (3 marks) — 9 marks
Answer all 3 questions, each carrying 3 marks.
Q1. Explain the process of photosynthesis with a chemical equation. (3 marks)
Answer: Photosynthesis uses sunlight, water, and carbon dioxide to produce glucose and oxygen. 6CO2 + 6H2O + light -> C6H12O6 + 6O2
Q2. Describe the human digestive system and the role of different organs. (3 marks)
Answer: Mouth breaks down food mechanically; stomach chemically; small intestine absorbs nutrients; large intestine absorbs water.
Q3. What are renewable and non-renewable resources? Give examples of each. (3 marks)
Answer: Renewable: can be regenerated (solar, wind, water). Non-renewable: limited supply (coal, oil, natural gas).
Section D - Long Answer (5 marks) — 10 marks
Answer all questions; each carrying 5 marks. Answer 2 out of 3 questions.
Q1. Draw and label a diagram of plant and animal cells. Explain the differences. (5 marks)
Answer: Plant cells have cell wall, large vacuole, chloroplasts. Animal cells lack these. Both have nucleus, mitochondria, ribosomes.
Q2. Explain Newton's laws of motion with practical examples. (5 marks)
Answer: 1st: Objects remain at rest unless acted upon. 2nd: F=ma. 3rd: Action-reaction pairs. Example: Pushing a book accelerates it.
