I remember there was a question asking about photoionisation. ( 2 marks?)
Another question about how to estimate the population of sundews, a type of insect eating plant, in a marshy bog area. ( 5 marks )
The second part to this question was asking why it is beneficial to the sundews to eat insects when there is a low concentration of nutrients in the soil ( 2 marks ?)
There was another question about calculating the volume of distilled water and the concentrated IAA solution to make 40cm^3 of the solution with a concentration of 10 parts per million? ( I really can't remember the question that well, I just know I struggled with it )
