    Do you know this question: "Using the chromosomes referred to in part (b) (ii), show, using a Punnett square or
    otherwise, that a child stands an equal chance of being male or female. "

    Did you have to draw a chromosome cross out or just use XX and XY and cross those?

    I think you could have done it any way. I just crossed the XX and XY

    i done a square thing with an x and y on each axis so thai t came out as 2 xy's and 2 xx's

    Thanks a mill. That's what I done too. It was the simplest cross I have ever done. I was surprised the genetics question wasn't harder.

    That's because the majority of people who do it are Russian, same with Polish, Bulgarian, Czech etc.

    Jesus the paper wasn't that hard! There was a full question on hormones which was piss easy, human reproduction was nothing out of the ordinary and a full question in bacteria which was expected to come up??? The ecology question in section c, you could have got almost full marks from just reading a passage!! The marking scheme will be open to interpretation to some of the questions such as that last question on bacteria in hospitals... If you done your work throughout the year you can't complain... Obviously people who crammed didn't do well and are giving out coz biology is the biggest syllabus on the leaving cert, yop A1 thank you state examination ;)
    i want to see how you do in august, youre gonna look like an absolute gob****e if you dont get an a..

    im just after remembering for the hormone question i couldnt think of any other than sexual ones, so for advantages/disadvantages for adrenaline i wrote it can give you energy and make you happy and for disadavantage i wrote too much can make you too energised and find it hard to sleep :pac:

    XS: Grave's disease/weight loss
    Deficiency: Cretinism/weight gain

    Advantages and disadvantages? That wasn't even asked.

    It was symptoms of over and under production of the hormone.

    That ain't advantages and disadvantages to me anyway.

    sorry i couldnt think of how it was phrased exactly, its kind of the same thing though?


  • Registered Users Posts: 206 ✭✭yoppo


    Would cretinism alone be ok for deficiency and bulging eyes for excess? Couldnt think of graves disease!

    In the exam I said weight loss for XS and weight gain for deficiency.
    Bulgeing eyes is a symptom of Grave's so you're grand!

    I said movement. I was thinking of the similar question from Ag. Crap. Hopes its accepted


    The correct answer is heat as every organism uses the chemical energy they obtain (food) to carry out respiration.
    Respiration is only about 40% efficient, the rest is lost as heat and is stored in the bonds of H2O and CO2.

    I've been teaching Biology for over 7 years now and that was definitely a strange paper.

    The very fact that Ecology didn't come up as Q.10 was extremely strange.
    Ecology is a banker topic and it proved that way again yesterday with a short question (20 marks) and experiment question (30 marks) and a part of a long question (30 marks).
    There's really no excuse for not knowing your Ecology.
    It made up 80/400 marks or 20% of the paper if you wanted it to.

    Many students can complain that there wasn't much human biology BUT, there was an entire question on human reproduction and another one on hormones.

    I liked the photosynthesis question, but the topics of respiration and photosynthesis are STILL being asked at a very basic level, even on the higher level paper so students are still getting away lightly IMO

    The OL paper was ridiculously hard, a lot of students who dropped down on the day were in for a shock.

    Could you have said excretion instead of heat?
