Every sheet in August 1995
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 1995Where in a plant are stem cells found?
- 2nd August 1995Name the process by which dissolved sugars are transported in the phloem.
- 3rd August 1995Why is photosynthesis described as endothermic?
- 4th August 1995A plant grown in the shade is shorter than a genetically identical plant of the same species grown in full sunlight. State whether this difference is genetic variation, environmental variation, or both.
- 5th August 1995State one human activity that reduces the amount of land available for other organisms.
- 6th August 1995State the two substances that must both be present for iron to rust.
- 7th August 1995State the size range of a nanoparticle.
- 8th August 1995Why is aluminium extracted by electrolysis rather than by reduction with carbon?
- 9th August 1995Explain, using collision theory, why increasing the concentration of a reactant in solution increases the rate of a reaction.
- 10th August 1995Name the small molecule typically released as a by-product during condensation polymerisation.
- 11th August 1995Explain, in terms of gas molecules, why methane and water vapour, as well as carbon dioxide, are described as greenhouse gases.
- 12th August 1995What happens to the energy described as 'wasted' in a transfer?
- 13th August 1995A block has a volume of 50 cm^3 and a mass of 135 g. Calculate its density.
- 14th August 1995Explain the difference between irradiation and contamination.
- 15th August 1995A water wave has a frequency of 4 Hz and a wavelength of 0.5 m. Calculate its speed.
- 16th August 1995A transformer's primary coil is connected to a 12 V supply and has 60 turns. Calculate the number of turns needed on the secondary coil to produce an output of 3.0 V.
- 17th August 1995A cube-shaped model cell has sides of length 3 cm. Calculate the surface area to volume ratio of the cube. Give your answer in the form n : 1.
- 18th August 1995Name the products of protein digestion.
- 19th August 1995State the difference between an antibiotic and a painkiller.
- 20th August 1995Define a synapse.
- 21st August 1995Give one example of an abiotic factor that could affect where a plant species grows.
- 22nd August 1995Name the four stages usually considered in a life cycle assessment of a product.
- 23rd August 1995A student says that metals conduct electricity because they contain free-moving ions. Explain why this statement is incorrect, and give the correct explanation.
- 24th August 1995Convert 250 cubic centimetres into cubic decimetres.
- 25th August 1995A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide. Heating must be continued throughout the reaction for it to keep going. State whether this thermal decomposition reaction is exothermic or endothermic, and explain your reasoning.
- 26th August 1995State the general formula of the alkanes.
- 27th August 1995Write the formula for calculating an Rf value.
