Every sheet in August 1984
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 1984Name the process by which dissolved sugars are transported in the phloem.
- 2nd August 1984Why is photosynthesis described as endothermic?
- 3rd August 1984Give one piece of evidence that supports Darwin's theory of evolution by natural selection.
- 4th August 1984State one human activity that reduces the amount of land available for other organisms.
- 5th August 1984State the two substances that must both be present for iron to rust.
- 6th August 1984State the size range of a nanoparticle.
- 7th August 1984Why is aluminium extracted by electrolysis rather than by reduction with carbon?
- 8th August 1984Explain, using collision theory, why increasing the concentration of a reactant in solution increases the rate of a reaction.
- 9th August 1984Name the two methods used to produce ethanol industrially.
- 10th August 1984Name the two gases produced by photosynthesis and the substance it consumes alongside carbon dioxide.
- 11th August 1984What happens to the energy described as 'wasted' in a transfer?
- 12th August 1984Name the change of state when a liquid becomes a gas throughout the liquid, at its boiling point.
- 13th August 1984Explain the difference between irradiation and contamination.
- 14th August 1984State whether sound waves are transverse or longitudinal.
- 15th August 1984State the name of the component at the centre of a transformer's primary and secondary coils, and state its purpose.
- 16th August 1984A student views a red blood cell at a magnification of x2000. The image of the cell measures 20 mm across. Calculate the real width of the cell, giving your answer in micrometres (um).
- 17th August 1984Name the products of protein digestion.
- 18th August 1984State the difference between an antibiotic and a painkiller.
- 19th August 1984State why a reflex action is described as involuntary.
- 20th August 1984A student counts 3, 5, 4 and 8 dandelion plants in four separate 1 m^2 quadrats. Calculate the mean number of dandelions per quadrat.
- 21st August 1984State the two main steps used to produce potable water from a fresh water source.
- 22nd August 1984State the charge on a calcium ion (Group 2).

- 28th August 1984What happens to the total resistance when a second resistor is added in parallel, and why?
- 29th August 1984What happens inside the nucleus when a beta particle is emitted?
- 30th August 1984A skateboarder of mass 55 kg moving at 4 m/s collides with and grabs onto a stationary shopping trolley of mass 20 kg, and they move off together. Calculate their combined velocity immediately after the collision.
- 31st August 1984Describe the shape of the magnetic field produced around a long straight wire carrying a current.
