Biology

1. [Biology Paper 1 - 3 Marks] Explain how bile helps the digestion of lipids.

2. [Biology Paper 1 - 3 Marks] A student uses a potometer to measure water uptake by a leafy shoot. An air bubble moves 45 mm along a capillary tube in 10 minutes. The tube has a radius of 0.50 mm. Calculate the rate of water uptake in mm³ per minute.
Use: volume of water taken up = 3.14 × (radius)² × distance moved by the bubble

Chemistry

3. [Chemistry Paper 1 - 4 Marks] Calculate the maximum mass of zinc sulfate (ZnSO₄) produced when 4.05 g of zinc oxide (ZnO) reacts completely with excess sulfuric acid. (A_r: O = 16, S = 32, Zn = 65)

4. [Chemistry Paper 2 - 2 Marks] In a chromatography experiment, the solvent moved 8.0 cm from the start line. A food dye moved 3.6 cm from the start line. Calculate the R_f value of the dye.

Physics

5. [Physics Paper 1 - 3 Marks] A pendulum bob of mass 0.50 kg is raised 0.20 m above its lowest point. The gravitational field strength is 9.8 N/kg. Calculate the gravitational potential energy gained by the bob.

6. [Physics Paper 2 - 4 Marks] Explain how an airbag reduces the force on a car passenger during a collision.
