Biology (H)- The Aftermath...

alancork

I thought that was grand tbh, i got all section A done, 3 experiments, and 5 in section C..and still out an hour early! I was expecting the eye/ear tho, no sign!
Question 12 was tricky with the nitrogen cycle imho, left that out...happy overall tho..:D

izzyflusky

Same as u, the only thing is i only did one experiment. Was soo happy when i got the test cuz i was freakin out last nite n this mornin

Steve01

Overall I'm very happy, 99% sure I got the A. I did the photosynthesis and enzyme experiments on Section B, both questions were lovely. Section C was probably easier than its every been! I was finished all necessary questions by half 3 (half an hour each for sections A and B - my arse) so I did an extra one.
Section A was alright though I didn't like some of the questions, particularly the one on genetic crosses

izzyflusky

Yeah the crosses were easy but i wasnt sure bout those lines on top. i hope they were for XX n Xy, otherwise i got it wrong. A bit confusing tbh

alancork

in the short question on zylem, Q6, what are the two different types of zylem?couldnt remeber...hoping 4 a B or an A anyway...woo..:D

Nehpets

Wasn't planning on counting it in my 6 because earlier I was prepared to fail it. Thought it was easy relative to what I was thinking

izzyflusky

I was so pissed off when i couldnt answer that part cuz i was lookin at that diagram just before i left my house but didn't think we'd get anytin like that anyway

Selphie

Hope I got the B I needed, then again its kinda hard to tell with Bio, though I answered everything I could. Great experiments, photosynthesis and enzymes, Section A was fine except for the genetic crosses, couldn't work that out. Did all of section C and stayed in til the end. Happy enough, cause I thought it'd be much worse. My drawings are laughable though...total crap! Forgot a couple of things, but overall I think it went pretty well.

Corruptedmorals

Lovely! Did 2 experiments, left out photosynthesis, then did respiration, blood, breathing system, viruses, immunity, reproduction and hormones. Fantastic. Could have done ecology and genetics, but don't like DNA profiling or the nitrogen cycle.

Wrote so much that I finished 5 minutes before time. Got a D in the mocks, but this was far easier. Couldn't remember a beneficial use of viruses, but everything else was grand really. I'd be dissapointed with less than a b2. B1..or maybe even an A2.

They were Xylem Vessel and Xylem Tracheid.

I did every question on it, the entire paper. Absolutely delighted with it

carlowboy

Hopefully got an A1 there. Easiest paper they put up yet and the question on the lung was nearly a copy of the one in the Sample paper. Makes you wonder if they'll mark it hard though.

Bluefox21

yeah it was ok prob only got a b and I was looking for an A an economic benefit of viruses anyone get something for that I said chemical weapons

qz

Grand paper. I love the way you can just daydream for half an hour and still havve time to finish the paper with another hour to spare.
Such a relief to have it over with though. Now what to do during my 8 days of freedom?

And no I'm not studying.

izzyflusky

I actually thought of writing that, but at the end decided not to hahaha

Oatesy

viruses can be used to transfer healthy genes into the lungs of cycstic fobrosis sufferers . Better have got my marks for that

Assez Bien

Was an easy enough paper but i wasn't happy with that genetic cross question, like as a short question its a bit tricky for some! They're probably gonna rape us regarding the way its marked though, your answers will prob have to be spot on considering the way the state isn't happy with the amount of people opting for biology instead of physics or chemistry.

adam_ccfc

One beneficial example is GBV-C virus, which reduces death rates in HIV sufferers.

(I recommend Biology: Essential Exam Revision by Sarah Dilleen to anyone doing Bio LC next years )

izzyflusky

Did anyone here go to the crash course in trinity in january or february? cant remember when it was really, with joe reville or sumtin like that

Aye, I wrote about the retroviruses used in drugs for HIV.

Eddie Ere

I know this is an honours thread, but not bothering starting a new thread just for pass Biology.

Pass was pretty simple, short questions a doddle, experiments had the ''throw a quadrat over an area'' one

Sec C was mixed with Respo instead of Photo, very small part on Genetics and VERY little plants.. yay!

sezconz

dunno wat to think about it, was able to answer everything but still dunno!did anyone get the answer about the DNA in rats and using your knowledge in mitosis and DNA etc etc etc....didnt no where to start?!??!

-blondie-

Everyones making me feel worse about it! I found it kinda hard, I had been aming for a B1/A2 but now Im not sure I even got the B

They are all somatic (body) cells, so they are diploid, and contain chromosomes in homologous pairs, unlike sex cells, which are haploid, and would only contain half the DNA. Just throw in that mitosis results in daughter cells with the same number of chromosomes as the parent cell.

I'm feeling pretty much the same.. i probably did ok, but the exam was not what i expected..(i dunno what i expected though)..

for some reason i just really didnt like it:(

BlackMamba

thought it was grand. Thank god, i was having a painc attack all this morning!

Splinkk

Was over the moon. I worked my arse off all day yesterday after maths paper 2 for it and it really paid off.
Got a C2 in the mock, and would have been happy with any improvement on that, but now I think I could have gotten the A!

Steve01

That diagram for the mitosis question was appalling. Like if it was the same picture in the book I would have known without a doubt what phase it was in.
Out of interest what was the correct answer?

Metaphase.
I don't think it needed a better diagram really, you could get everything that was asked from the one given.

Metaphase, 2n=4, thats what I got.

adam_ccfc

Yeah it was obvious as sin, in fairness, if you actually knew the stages!

Like hell it was. It looked nothing like it does in the textbook and it was difficult to tell whether the chromosomes were arranged along the centre or whether they were moving apart. But since it looked like the spindle fibres weren't pulling apart (again, hard to tell) I went for metaphase and got the marks. So ha!

Bluefox21

nooooo thought it was anaphase..

ninebeanrows

My Short Questions were poor.

Q1 poor
Q2 what the hell was with the pyramid?
Q3 Said 2n = 8!!
Q4 Good
Q5 Think i got it
Q6 AHHHHHH I said Xylem crossed it out and said Phloem, i did say tracheids and vessels though.......

Not good not good at all

Did the Enzyme experiment all went well
Did the Photosyntheses experiment all went well

I thought the Long questions were very long! Just got my 4 questions finished! 30 mins spend on each.

Done the Question on Respiration and Enzyme = Good apart from last part of b) got abit confused.

Did Question on Lungs etc....... Went well although diagram not the best!

Viruses and Immunity went alright not 100% though

Male Reproduction and Hormones went well.

So overall looking at a B3 hopefully probably a C1.

Corruptedmorals

Metaphase yeah, but surely the diploid number was 8?

Marshy

What answers did people get for the xylem short question? Where is the vascular tissue in a dicot?

Marshy

Corruptedmorals wrote:

There were only 4 chromosomes though, unless I'm going blind

genericgoon

No each chromosome at that stage is made from two chromataids which when separated will form a new chromosome in each daugther cells nucleus. Dont forget the 2 cells need the same no. of chromosomes post-mitosis. Not too bad a paper. Id say a B to a A depending how things go.

I assume in the vascular bundles which are spread in circular shape around stem.

adam_ccfc

Corruptedmorals wrote:

No, the chromatids are going to be pulled apart into two groups of four, which will be in the nuclei of the new cells.

genericgoon wrote:

Yeah, inside of the vascular bundles.

genericgoon

I added the location of them for insurance.

Corruptedmorals

How much is each short question worth? 10 marks? Messed up a slight bit on the xylem one (xylem tracheid is NOWHERE in my book), then a bit on the genetics one and possibly on the mitosis one, but I'm pretty sure that the haploid number was 4, and diploid number was 8. Lost about 6 marks I'd say, then lost 6 marks for not getting the benefit of a virus...still in line for the A2..

genericgoon

Diploid number was 4

Corruptedmorals

Quiet.

genericgoon

Xd

adam_ccfc

You needn't have, the question said "in the stem".

Short questions are 20 marks. You can keep telling yourself 2n=8, its not going to make it right. The mother (my bio teacher) said its 2n=4.

genericgoon

Anyways a missed section of a short question isnt exactly the end of the world.

mateo

I thought the Short Answers were awful!!

I probably got about 60%, don't care that much though!

Corruptedmorals

Ah I'm not fussed or panicking, I still nailed experiments and long questions, which is enough for a B1.

genericgoon

Indeed its not too tough to scrape together about half marks in the A part even if you missed a few,
