Guys how did you find Biology Paper 21

[wonderland]

wow i think grade threshold will be 45 - 47......it cant be 50

 

[wonderland]

the enzyme was carbonic anhydrase
i wrote that significant of equation ..
THAT HYDROGEN CAUSE THE HAEMOGLOBIN TO DISSCIATE THE 4 OXYGEN MOLECULES AT THE RESPIRING TISSUES AND THE HYDROCARBONIC IONS LEAVES THE RED BLOOD CELL MOVING TO PLASMA LEAVING THE CELL WITH OVERALL NET OF POSITIVE CHARGE ...SO DIFFUSING IN OF CHLORINE IONS INTO THE CELL TO BECOME NEUTRAL..

The question was only 3 marks, i dont think that level of detail was necessary! but i guess more i better then less

but there's one guy here who said that our chem p21 was of 50 marks!!

 

[nerdybookworm]

ohh damn!!..my magnification is wrong!!:/..i juss hope the gt r low!!!....n i also got messed up in the carbondioxide question bcz i cldnt revise tht chp properly!!:/

guys i wrote the name of the enzyme ' carbonic anhydrease ' not ' carbonic anydrase ' ..... Will the examiner deduct mark for the spelling ??????????

Guys I did something SOOOOO STUPID! For the silliest easiest question, the metaphase one, I for some reason write the cytokines instead of centrioles move to the opposite poles!!! OMG I wont lose the whole 5 marks will I?!?!?! :'( I know stupid LOOOL but seriously how much marks would I lose?

 

[oohlala]

which variant is this?

No u will not lose the whole mark of course .... U will lose only 2 marks or 3 maxxxx !

this was 4 marks this question 2 not question 3

 

[Romeo10]

will it be wrong if i wrote carbonic anhydrease instead of anhydrase ??

 

[wonderland]

In the end, it's not going to matter how many breaths you took, but how many moments took your breath away (biology 21 was one)

 

[wonderland]

unfortunatory as it was 1 mark they will ........

 

[wonderland]

Romeo10 dont worry inshallah you will get A.....

Ques 1 was ez but i did da magnification wrong
Ques 2 ...it was a messsssss
Nd for dat ques bout da letters....hw many letters were repeated??
Andddd in da ques for labeling da MRNA....is it ok iv we rite pentose instead ov ribose sugar?:s
And in da last ques...y wasnt da baby vaccinated in first few months???

 

[libra94]

i think 2 of them were repeated, not sure
i also wrote pentose :/ i hope its correct
the baby wasnt vaccinated becuz he already had immunity (natural passive immunity) from his mother

 

[wonderland]

BABY already had immunity (natural passive immunity) from his mother IS INCOMPLETE SINCE OF THE FACT HOW
IT WAS BABY already had immunity (natural passive immunity) from his mother IN THE WOMB THROUGH PLACENTA..OR THROUGH BREAST MILK..........IT WAS 2 MARKS

2 OF THEM WERE REPEATED IN TABLE

 

[sweetyrox]

i dint write NATURAL .....i just wrote PASSIVE immunity nd i said so there was noo need ov da baby being vaccinated cause antibodies frm da mother are gonna be present....etc etc...so is dat rite??

 

[wonderland]

THEREFORE , AS POINT OF FACT, ALL PEOPLE TALKING ABOUT HOW DAMN EASY WAS IS FALSE.. BECAUSE PAPER WAS EASY BUT SOME WAS SMILTANEOUSLY VERY HARD...IT SEEMS TO ME AS IF THIS QUESTION 2 AND 3 WERE DIFFICULT FOR MANY SINCE BOTH WERE BASED ON SAME TOPIC ... NOW THINK IF SOMEONE DIDNT REVISE THIS TOPIC BOTH OF THE QUESTION WOULD HAVE BEEN NIGHTMARE FOR THEM .....
SO I PREDICT THE GRADE THRESHOLDS FOR BIOLOGY 21 WILL BE 45 SINCE OF REALITY THAT IT WAS HARDER THAN BIOLOGY 22 AND 23 AS I HAVE BEEN TO THEIR FORUMS ... AND THERE WAS ONE OF ENZYME SACRASE THERE WAS 5 MARKS QUESTION SO PEOPLE CAN EASILY LOSE MARKS THERE TOO... (IN THESE TYPE OF QUESTION WE HAVE TO PLAY WITH NUMBERS AS MY BIOLOGY TEACHER TOLD THIS IN CLASS -LOL) he gave oct/nov 2009 paper 22 in mocks.... it have question like that...........(SO GRADE THRESHOLDS WILL BE SOMETHING 45 BUT BELOW THAN 47 AND MORE THAN 42) :good: :friends: ardon:
