Aqa a level biology question
Hello all,
If anyone can help here I would very grateful.
I don't have a clue as to how to arrive at this answer:
Calculate the ratio of the mean rate of uptake of chloride ions in the first hour to the rate of uptake of chloride ions in the second hour for group B plants.
At 60 minutes the total uptake of chloride ions was 360 and at 120 minutes it was 470. The answer is 3.3:1.
