yeah we use the %s so its easy to compare the data from different medium!!

how did u calculate the relative absorption rate?
and in the procedure did u use change in mass to detect glucose?
and one last Q how is the buffer oxygenated?

for the relative rate...final mass of intestine(g) minus initial mass of intestine(g) divided by time
yes i did!
i wrote that oxygen is bubbled in the buffer solution in an air-tight flask and kept for 2hrs!!

Question 2 according to me I found intial mass to get to fixed mass and measured for time, rate would be (1/t), conclusion was easy ummm oxygente lol i said add a reducing agent, i didn't think bubble it was 2 marks never guessed :/, first question was good until the t-test teacher confused us right before the exam but i think i dod it correct not sure umm the conclusion for that i wrote % sucrose increases germination rate increase's. overall the paper looked easy i think its dillusion to think you did well just because it looked easy so all we can do right now is PRAY to ALLAH and ask for a great results ALLAH (swt) will give what you deserve and more, also based on how much effort you put. Inshallah all A*:)
