biology paper 1 doubts

[Idolfanatic95]

What did you answer for the question where we were supposed to calculate the volume of blood carrying oxygen in one minute?
I went for D which is 950

I wrote C-325

 

[Irfan1995]

So what did u answer for the phospholipids question??? Which one was not a function of phospholipids??

It's definately not cytokinesis. In fact, phospholipids are the main requirement for cytokinesis.

 

[Idolfanatic95]

Length of Prakoaryotes ? A or B

Most probably B

 

[yazan1995]

GT people ??? what do you think . don't give stupid GT like 36 and 35 . paper wasn't that easy to reach 35 or 36

 

[Idolfanatic95]

For the magnification question what answer did u get? I think i got 50.

Yep 50

 

[Idolfanatic95]

Are you

Clots are formed! n they cause complete blockage of oxygen supply to the heart!!!.........firstly, fatty deposits ,then plaques n then blood clots are formed leading to thrombsis

u sure abt this?

 

[Idolfanatic95]

That was a past paper question! And the answer was B.....

It was sumthign like skeletal muscle do not tense much and so cant push blood upwards. repeated question.

 

[Idolfanatic95]

I think it won't be less than 35/40 for an A .

In may/june it was 33. I guess it wud be lower than that this time. Mayb 30/31

 

[Irfan1995]

I found the paper quite easy compared to may/june, with several repeated questions, so I don't think Cambridge will be lenient with the GT this time. So I'm honestly expecting above 35.

Above 35 is a bit too much i think. The gt for paper 12 is usually lower than 11 or 13

 

[Irfan1995]

Okay, let's take a look at may/june '10:
GT for Paper 11 was 36/40
Mean score was around 23/40.
Six questions were difficult (less than 40% of candidates were able to answer)

Are you
u sure abt this?

Truly speaking! I thought all of them should be correct! But the mre possible one's in my view were 1, 3 & 4......... as 2 was leading more towards artherosclerosis

Its not about the Cambridge being lenient or not, it depends on the body of students giving that paper. There might be thousands of other people, not on the forums, who gave this exam and found it relatively more difficult than u did.
November thresholds are usually lower than June thresholds, lets just hope for the best..

In my opinion, there were about 3-4 tricky questions.

And that's why the examiner's report took into consideration every single candidate who applied. As mentioned, the average score for may/june '10 was 23/40 and the GT was 36/40.

The GT is not made taking into consideration the average students.
Cambridge gives 10% of its highest scorers an A...

Yep i did 1,3, 4 too. I wasnt really sure of the fact tht fatty acids accumulate in veins too.

the option ddnt say "fatty acids" it said fatty deposits or something like that.
And yes, they do get deposited in the arteries and veins, which narrows the diameter of the blood vessel (possibly the coronary artery) therefore reducing the blood supply (oxygen and nutrients) to the heart. Reduced oxygen to the cardiac muscle, the heart fails to work, ie. heart attack.

atherosclerosis can cause a heart attack too, if the thrombus is in a coronary artery.

Then what is it ???

seriously ? easier? i don't think so. this paper was harder than may/june in my opinion.
