How was paper went of BIOLOGY 5090/22

In paper 2 what was the answer for why do women need iron supplements and do they cut marks on writing answers off the lines?

it was such a simple question!! they need iron supplements in order to compensate for d blood lost during menstruation.And no marks r deducted for writing off d lines

It said the water i think would be boiled,i'm quite sure cuz i read it multiple times,and it would be needed to destroy any bacteria that might be present.We had to remove the colored wala option.

no.if d solution is prepared after boiling,yeast will be denatured whereas d experiment was investigating anaerobic respiration in YEAST

Im saying it would be boiled and cooled before yeast is added.The question stated that i'm sure

u misunderstood d question,i think

I chose drink A the reason being that it caused the greatest amount of water to be released from the body thus resulting in dehydration.
In the mosquito one I chose the one that said microscopic parasite pathogen

I chose A too but a lot of people were saying C is the correct answer

 

[Dani 97]

I also chose drink A but SIR IMRAN MERCHANT told that it is drink C now GOD knows what is right

 

[Mazin Junaid]

No thats actually right cause when you boil the water sirf jab hi anaerobic respiration hogi warna the O² in the water would Be supplied To the yeast

i jst wish drink C turns out to b d correct answer

 

[Maisha labiba]

in A more urine produced urine is 95% water so in A more urine produces and ur also sweating ur osmotic gradient is distorted and ur body gets dehydrated cells shrink body dsnt function properly and less water absorbed by kidneys

Exactly. Thats why i chose A

for anearobic respiration to occur,d question mentioned d use of oil layer on solution so dat oxygen does not dissolve.therefore,water did nt need to b boiled.i m pretty sure dat d option i chose was correct

 

[Maisha labiba]

No its not mosquito, pathogen, vector bcoz it asked for wht "CAUSES" malaria and mosquitoes dont "CAUSE" malaria, they "SPREAD" it which is why they are called "VECTORS" The answer shud be parasite, pathogen, microscopic wala cuz thts wht "CAUSES" the disease

damn. another mistake :'(

You have to realize that water already has dissolved water the layer of oil wouldn't stop the oxygen alreqdy dissolved from reacting....choro yaar mene bhi ye wala mcq galat kiya hai koi nahi hota hai

 

[Mazin Junaid]

i jst wish drink C turns out to b d correct answer

Baddua to mat do yaar

i m nt gonna argue more!

In paper 2 what was the answer for why do women need iron supplements and do they cut marks on writing answers off the lines?

no I asked my bio teacher she said no marks cut for writing off the line in P 2

 

[rammy97]

It said difference in water potential between cell sap and root i think.Thats why it would cause the water to move up.

That would cause the water to move in the root hair CELL, jis ke "cell sap" ki baat horahi hai... the stem (xylem) has NO cell sap remember?

 

[rammy97]

What did you guys choose for the last mcq about the dominant allie. I choose part c that it is always shows its penotype in homozygous and hetrozygous ?

yes thts right!

 

[ovoxotillweoverdose]

yes thts right!

Wooh yeaa

 

[ovoxotillweoverdose]

What did you guys do for the mcq about aerobic respiration in muscles? A was wrong cz it had ethanol. B and c had lactic acid while d had wather co2 and heat ?
