i said as there was more glucose, the plant respired more, which creates carbon dioxide and water. as there is water created, the guard cells will open the stoma to lose excess water.
DONT TRUST ME
i have no clue if that is correct

Would I get the mark for the question which asked what was in the test tube (the one that was empty).

I put water - would this get me the mark?

I think it was distilled water. I'm so scared because I kept getting like 55/70 in my bio mocks but i feel like i screwed up today. Maybe I haven't, I don't know :smile:

Anyone write Type 2 Diabetes for a non-communicable disease that people with obesity have a risk factor for? Also for the national policy I said take vigorous exercise.

Anyone knows why starch must be digested? I wrote to be broken down and stored as glucose which the body uses for respiration to produce energy.
and also.. WTF is the liquid at 0g/dm3.. I pretty sure its still iodine.. I think its a trick question


i put starch is a big food molecule and cannot be absorbed so must be digested before it is absorbed and the liquid was water
What did people write about the 3 tree and carbon dioxide question?

I had 3 minutes left and that was the question I had left blank but after rereading it I understood it and I'm not sure if it is the right answer but I put down the mean to be 1.03
