How was Biology Paper 51 ...

[wonderland]

I felt paper was easy ... What do you guys think - how was the paper ?

 

[Otaiba13]

yeah very easy !!!!! i finished 30 mins before the time!!!!!!1 but i didnt like q2 !!

 

[wonderland]

Why do we use the germinating percentage? ... what did you write.

 

[wonderland]

In the second question we have outline the procedure...what did you write..?

what ques was dis?:/

 

[earthling]

I

Why do we use the germinating percentage? ... what did you write.

I wrote coz its easy to compare percentages?

 

[earthling]

What do u think the gt will be?

 

[Otaiba13]

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

 

[Otaiba13]

the procedure question was strange so less marks and so less space!!!!!

 

[walkthetalk]

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?

Can u believe I did not know the answer to ALL those questions?

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!!

 

[walkthetalk]

oh man! i wrote put a photosynthetic plant in buffer

 

[walkthetalk]

Can u believe I did not know the answer to ALL those questions?

its ok!! those WERE the hard ones in the paper

 

[nerdybookworm]

paper was easy..i hated Q2 ..oxygenated buffer was so dayum weird n much less space given for procedure...

 

[nerdybookworm]

i wrote bout the % transmission and absortion..the use of calorimeter...for the rate..idk y the **** i dn use 1/rate //:/

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*

 

[sweetyrox]

Expected gt??

 

[The King XII]

Expected gt??

I think ranging from 17-23/30, not more than 24.

PLZZ wat did u write in the procedure question ???
