[raiyanfarrukh]

[Adorkableme]

if u see all past papers the max gt was about 32 not more than that!!and what was the answer for the % thing??

 

[Adorkableme]

I got 60 something, Can't remember

 

[raiyanfarrukh]

what do u think is it ryt?? because i also got in 60's but some of my friends got in 30's something!!!

 

[Mclovin]

i got 37%

 

[pearl angel]

i got 38%

 

[PoIsOngAlLeRy]

i got 40%...plus this answer kinda makes more sense...cuz wen u look at the picture..u can tell the blockage is
less thn half...ryt..???

 

[incorrectlytrue]

Wow. I got 47%... Some people in my class got 44, and others got 40%.. Ahahaa.

less thn half...ryt..???

i also got 40! which is correct because they ask for percentage change so answer would be -40% !!!

 

[raiyanfarrukh]

guys it's wrong because they were asking u the percentage of change in area of that lumen not the percentage of blockage!! so it should be in 60's because blockage is less than 50% of the area so the new area will be more than 50%

 

[sahooor_95]

i wrote 44.44% others got 47 , 41 , 39
i think that is the correct range

 

[PoIsOngAlLeRy]

guys it's wrong because they were asking u the percentage of change in area of that lumen not the percentage of blockage!! so it should be in 60's because blockage is less than 50% of the area so the new area will be more than 50%

buh they didn't ask us da new area...they asked us da change in area...anywayz...its alrite...

 

[PoIsOngAlLeRy]

i also got 40! which is correct because they ask for percentage change so answer would be -40% !!!

oh..yeaa...i didn't put da minus sign thou....damn it....will they cut marks for tht...???

1st question was ok, not very easy, but overall the paper was good! gt should be around 31 i think
i got the percentage as 60%!
1st questions asked about a control, what was it?

They asked us to set up a control for this experiment, which means, using 10cm^3 of distilled water , without any volume of enzyme solution.

 

[kaz619]

The question about the artery asked, what is the percentage change in the area of the lumen
The area of lumen changed due to the blockage,
the percentage of blockage = ~30/~80 x 100 = % change in area of lumen

i'm not entirely sure about this, but it's what seems to be logical

I got like 39.6%.

The seond question was a little tricky. Did you draw the entire lung tissue you saw under the microscope or just the alveoli? I drew the whole thing with the double layered alveoli+ a nucleus. I'm sure I got the nucleus wrong though. :/

i drew 2 alveolis, each surrounded by 1 thin layer of squamous epithilum cell with the nucleus, and one more layer of capillary around it
