Mm nice enough section B and C but short questions were terrible i didnt get half the stuff!!

Saaaaz

can anyone name out the topics of the section C questions?

reznov

AH CRAP. THATS IT. ACQUIRED AND INHERITED MUTATIONS.
damn it.

Didn't get to draw a single dick or fanny. Gutted.

In seriousness though it wasn't the best paper for me. Experiments went really well, Short qs were kinda crap but I filled in everyone anyway and two of my long qs were good, one was okay, and one was crap. Was hoping for a B3 but now I highly doubt I got that. Maybe a C2/3 at best.

In happier news only two more exams for me and then I'm free!!!!! :D:D

thought it went well, one question i could not decipher for love nor money was that Q11 a)i) what are the two types of nitrogenous bases? looked it up in the book there the answer is purines and pyramidines. can safely say i have never heard of that before :L section B was sweet, and i loved the long question on the nervous system, got an a1 in the mock so hopefully ill get it again

Oh god that question. I knew the answer, but in the exam I spent ten minutes going "is the word pyridenes or pyrimidines"... I WROTE THE RIGHT ONE

Question 10, in the part where it talked about the alleles being linked...it asked for the two gametes that occur most frequently, but there are only two gametes in total no?

Thought it was a grand paper, for those who knew a broad range of the topics. A few people in my year who had always done great biology found it very difficult

Champion Gold

I got pyrimidines and purines and was very proud of myself

I said gene mutations and chromosome mutations *facepalm*

What an awesome paper. Really happy. The short question on the bone was weird and hard to read the diagram but a fine paper for those with a genuine interest in biology. A bit unfair for those who solely covered the course as it did require some abstract thinking and general knowledge/wits but I'm so hoping I did enough for the a1! I really enjoyed it anyway!

what about gene or chromosome mutations?

edit: no I'm right, if you inherit a mutation it's not a mutation

Prettyyy sure I wrote pyridamines...oops haha think they allow for spelling mistakes though

Acquired and Inherited mutations?? I thought that was immunity :L I said chromosome and gene mutations.. Overall I liked the paper.. A few weird questions but as expected hopefully the A1

FreeFallin94

Ugh I knew Purines and Pyrimidines but for some reason I though it meant to give 2 examples of the actual bases so I wrote thymine and cytosine! So annoying! Was really hoping for an A1 but I don't think I will now... thought it was a bit of a weird paper to be honest!

I'm pretty sure gene and chromosome mutations is right, I read the whole book last night and distinctly remember reading that :L

What answers did people get in the food short question?

The ones about the chemical difference of amino acid and monosaccharide?
chemical common between fats and carbohydrates?

Chromosome and Gene mutations is right, I'm nearly positive.

Is it not gene/chromosome??

Difference is that amino acids contain nitrogen (as they're proteins) whereas monosaccharides don't (they're carbohydrates).

The common chemical between fats and carbs are CHO.

Can someone please post the topics of the section C questions, have a horrible feeling that I left one out!! :O pleeeeaaase!!

DepoProvera

A few things came up that I had never heard of: namely introduction of change of base sequence and leaf yeast in July/march and leaf yeast graph.. Manage to get all questions done with time to check everything woop

an amino acid has nitrogen, a monosaccharide does not.

3 chemicals common between fats and carbohydrates: CHO

There isn't nitrogen in fats?

Wooo I said that for them, 20/20 for that one:D I reckon section A was good, section B was good and section C was tricky.. Hoping for a low B - high C:)

Carbs nor fats have nitrogen. Looks like you lost 6marks

Sound paper!

I completely guessed it and said protein for the first and lipids for the second..didn't have a notion!

You just contradicted yourself there.. both carbs and fats are made of hydrogen, carbon and oxygen

I thought that was a very good paper over all... did nearly every question on the paper in 2 hours didn't go hugely into specifics or details of any one thing.. nice and evenly spread out imo.

Section A and B were lovely. However section C wasn't the nicest, couldn't awnser for the life of me two of the q's so I had no choice in the matter.
I'm sure I got a high B, pushing it to say an A2. But it's really annoying knowing you could have gotten an A1 even if you just did an extra days study :-( ahh well, theres always next yea...oh wait.

What were the parts of the bone in Q3?? The diagram really confused me

Didn't really like this paper.

ya you're right it's chromosome and gene mutations. Thats what I put down.
