The diagram shows a respirometer setup used to investigate the rate of respiration in woodlice.
Which row in the table correctly identifies the biological process taking place in Tube 1, the role of potassium hydroxide (KOH\text{KOH}KOH), and the direction of movement of the coloured liquid droplet?
