We're not bullying but you're being kinda rude :/Stop bullying me or ill 360 degree no scope u guys :/
Did onion epidermis or yeast come in P33?
If not then what experiment was it?
Test for reducing and non-reducing sugar both gave brick red ppt so there is no proof that non-reducing sugar will also be present...the question asks about the molecules which MUST be present, not those which CAN be presentIdk how there is absence of non-reducing sugars here :-/
Could anyone explain why C is the answer ad not A?
A student carried out four tests for biological molecules on a sample of milk.
The tests and their results were as follows.
● Heating to 80 °C with Benedict’s solution gave a brick red colour.
● Adding Biuret solution gave a purple colour. ● Adding iodine solution gave an orange colour.
● Boiling with acid, followed by neutralisation, then heating to 80 °C with Benedict’s solution gave a brick red colour.
Which biological molecules must be present in the milk?
1 non-reducing sugars
2 protein
3 reducing sugars
4 starch
A 1, 2 and 3
B 1 and 2 only
C 2 and 3 only
D 3 and 4

You saw the examiner report right ......Test for reducing and non-reducing sugar both gave brick red ppt so there is no proof that non-reducing sugar will also be present...the question asks about the molecules which MUST be present, not those which CAN be present
NOYou saw the examiner report right ......
No it combines with amine group to form carbaminohaemoglobinGuys does Carbon dioxide combine with haem group of a haemoglobin molecule?
I think it binds to amine (NH2) group of haemoglobinGuys does Carbon dioxide combine with haem group of a haemoglobin molecule?
The anticodon for serine is UCA so the codon is AGU and hence the DNA triplet is TCABio View attachment 63761 View attachment 63762 Bombs Away!!!View attachment 63760 I understand that the objective lens should be x10 but why must the eyepiece lens be x5?
The TOTAL magnification must be calculated...so for the largest number of cells, the total magnification must be lowest which is x50 for AI understand that the objective lens should be x10 but why must the eyepiece lens be x5?
After dividing once, all DNA will be 14+15 so all will be at L and after 2 divisions, there will be half 14+14 and half 15+14Bio View attachment 63761 View attachment 63762 Bombs Away!!!View attachment 63760 I understand that the objective lens should be x10 but why must the eyepiece lens be x5?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
