    Parhorry, sorry if I got your name wrong, you were right, it asked what simple compound gives H to produce Carbohydrates, so NADPH is right. The paper is up now as well.

    No worries :)

    Totally agree with the comments saying it was a "weird" paper , everything seemed so jumbled up definitely one of those papers where if you left out chapers you could be really screwed!

    Happy enough with it :) very nice paper!

    I liked the experiment with all the bits in it, though. You know, the one asking you all sorts of random parts of experiments you either know or don't know? I liked not having to go into measurements and apparatus in detail-I liked jotting stuff!


  • Registered Users Posts: 63 ✭✭Hatred


    I did alright. Was hoping for an A but probably got a high B. still thats plenty of points :D

    I dont mean too be a dick but good. If you cant get an A1 in Leaving Cert you cannot be allowed become a doctor. Harsh but its peoples lives you deal with. You either know it entirelyor you dont do it. Im sure there are plenty of doctors out there who did bad in Biology and thats also why we have idiots trying to kill perfectly healthy babies.

    And you gotta love tha babies.:pac:


    That's a bit harsh.
    I seriously doubt that if those docters had known all about the sexual reproductive sytems of plants it would have helped.

    I don't think you have to do measurements anyway. Like you don't have to stay "I added in 5ml of X and 10ml of Y"etc.

    Ahhhh crap. I wrote that the heart was found in the 'thorassic' cavity, not the 'thoracic' cavity!!! I hope the examiners are kind!


  • Closed Accounts Posts: 166 ✭✭A19B1C12


    Is tissue culture taking tissue from one part of the body to serve another?

    And is tissue there to protect? I also said meristematic was tissue in plants. Are these right?


  • Registered Users Posts: 297 ✭✭BarnhallBull


    Stupid question warning...

    9 (b) What plant tissue did you use? - seed? :confused:

    I wrote chest cavity :P

    I'm hoping they are really kind....

    Actually that confused me as well, I just said cress seed... Also I said abdomen for the cavity, cause I was clueless :P

    yeah, ah sure some people just like being mean. i know i'll make a great doc. And no, i doubt know how plants reproduce will help people, unless somehow it happens inside someones body... :p


  • Registered Users Posts: 297 ✭✭BarnhallBull


    Tissue culture is the method of growing cells outside of an organism.
    About protection, it depends on the tissue, ot sure about that answer for plants, i'd have said ground/vascular/dermal.

    As for chest cavity, that should get the marks

    tissue culture is growing tissues in the lab for medical purposes.

    meristematic is a tissue yes.:)

    Right. Here is the paper. http://examinations.ie/archive/exampapers/2010/LC025ALP000EV.pdf

    The first genetics question. Somebody please explain to me how you got 100%. I cannot work it out. I got all the other ones right.


  • Closed Accounts Posts: 121 ✭✭starry nights

    SAME!!! i got 50%

    cos FFxFf =

    F;F x F;f =

    FF; Ff; FF; Ff


  • Closed Accounts Posts: 302 ✭✭lallychops


    opened the paper and there was definitely something odd about it....didnt look like many of he past papers id ever seen....genetics was nasty.... protein synthsis? not even true genetics......also i didnt think it was that fairly spaced....not even 1 fully reliable question appeared.....all mixed and matched.....yuck is all i can say to that......


  • Registered Users Posts: 297 ✭✭BarnhallBull


    BB x Bb = BB, Bb, BB, Bb.. 100%

    It said that full wings was dominant to vestigial. Because the cross was with homozygous dominant and heterozygous parents the only possibilities of offspring were homozygous dominant and heterozygous, and the heterozygous condition will also have full wings because it is the dominant allele of the two. So they both have full wings, 100%


  • Closed Accounts Posts: 96 ✭✭Indigo Sunrise


    D-full wings, d-vest
    parents: DD(homozygous for full wings) x Dd (heterozygous)
    gametes: D x D, d
    offspring: DD, Dd
    both results have full wings so it's 100%

    That's what I did anyway. Dunno why I used the letter D but whatever :D

    All are expressing the dominant phenotype

    Ah shít. Ye're right. 100% it is. Don't know how I didn't get that. Cheers lads.

    did yo think that for the amount of work you had to do to get that out its hardly worth the marks their gonna give???

    Took 5 mins for 5% of the paper, i'd say it was absolutely worth it

    Hate to break it to you, but marks add up to points and points add up to college courses.

    BB x Bb = BB, Bb, BB, Bb.. 100%



    you're wrong.... if thats the dalmation one you're doing....
    it says the two parents are heterozygous =


    Bb x Bb=

    B; b x B;b =

    BB; Bb; Bb; bb

    therefoe 75% black

    Ah crap...no marks for tissue culture then:(

    Said it was used to prevent injuries :L


  • Registered Users Posts: 297 ✭✭BarnhallBull


    I was doing the first one, I thought that's the one you wanted explained?

    I know the dalmation one was 75%

    Well I failed or else i got a D3/2! But thats to be expected, i mainly studied photosynthesis, ecology and the nephron and male reproduction. well i say "mainly", thats all i studied. and i could barely do the questions.

    The short Qs were ok, loved the ecology one, never studied amoeba so i bullsh*ted it!

    The experiments.. wel i didnt bother studying the heart one coz i didnt think it would come up, how wrong was i! i made it up...

    the one with the number of experiment Qs in one was grand i could answer that!

    my teacher never got around to the plant experiment so i didnt have the slightest clue!!!

    i did the ecology question, that was ok, then did the photosyntheses one, i ended up writing like a page for when it asked to describe the pathway 1 and 2, so stupid only worth little marks :L

    over all i did ****... did anyone else fail with me?D:
