The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

  1. 1st May 2001State the function of the valves in the heart and in veins.
  2. 2nd May 2001Complete the word equation for anaerobic respiration in yeast: glucose -> ___ + ___
  3. 3rd May 2001State one risk factor linked to type 2 diabetes.
  4. 4th May 2001The Arctic fox has small, rounded ears compared with the desert fennec fox, which has very large ears. State whether this is a structural, behavioural or functional adaptation, and explain how it helps the Arctic fox survive.
  5. 5th May 2001Give one reason distillation of seawater requires a large energy input.
  6. 6th May 2001Write the formula of calcium chloride and explain the ratio.
  7. 7th May 2001A student reacts 2.4 g of magnesium with excess dilute hydrochloric acid: Mg + 2HCl -> MgCl2 + H2. Relative atomic mass of Mg = 24. Calculate the number of moles of hydrogen gas produced.
  8. 8th May 2001Hydrogen reacts with chlorine to form hydrogen chloride: H2 + Cl2 -> 2HCl. Use the bond energies given to calculate the overall energy change for this reaction. Bond energies: H-H = 436 kJ/mol, Cl-Cl = 243 kJ/mol, H-Cl = 432 kJ/mol.
