confirmed and 90% sure for paper 32 that the experiment of the effect of surface area to volume ratio of potato discs on rate of osmosis
the slide will be somehow weird and will be a section in the liver but don't worry only plan diagram needed

yess it includes hydrogen peroxide, my teacher who prepares the lab equipment said so, and the test might be like the one in the specimen where u have to count the number of bubbles per min and see the effect of concentration on the number of bubbles, so most probably there will be serial dilution , and the slide include a dicot stem where u have to draw

I was told that it could probably be counting bubbles by changing temperate of the beaker or by changing concentration of H2O2

my teacher didn't say anything about preparing water bath, only hydrogen peroxide and the equipments like in the specimen paper, so he guessed it will be the effect of different concentrations on the number of bubbles
