In this respirometer, the movement of coloured liquid indicates that....

• the organism is giving out carbon dioxide

• the soda lime is releasing carbon dioxide

• the organism is taking in oxygen

• the soda lime is absorbing oxygen

Which of the following procedures would not improve the reliability or validity of the result?

• using the same volume of soda lime in each repeat experiment?

• repeating the experiment with the same grasshopper and calclulating the average

• pooling class results where each group used a different grasshopper

• allowing a standard period of acclimatisation before taking readings.
