Biology Higher Level

I really felt like the Respiration Question was annoying.
The questions were easy but I contstantly felt like it should have been asking for more info. It kept saying 'state' and 'name'.

Yeah took me a few mins to pick a 4th. I did the one on the eye and Vegetative propogation. Dont think I did too badly.

Did anyone else write about 2 eyes giving you a sense of depth perception?

didn't do the question but that's definately correct fairplay. that question nearly made me sick when i saw it. thankfully i could avoid it.

I really need an A1 in biology so I'm not overjoyed with todays paper. I think there were enough little 3 markers that I mightn't have got which could bring down my grade slightly, hmm! Those "notes" were so annoying, I hadn't a clue what to write. My notes ranged from a paragraph to a sentence =/

I almost completely made up the quantative survey question, but it was an extra question so I wasn't too fussed.

With only 3 minutes to go til the end of the exam I realised I hadn't answered the bit on a breathing disorder which could have been a handy few marks, luckily I managed to scribble down my anseer in time!

For the photosynthesis graph does anyone know were we meant to include a unit of measurement or any values on the axes? I just called my axes "Rate of photosynthesis" and "light intensity" and didn't put in any numbers or units of meausrement =/

I didnt put in numbers but I put in the units of measurement as Light Intensity in Luxes and Rate of Photosynthesis in Bubbles per Minute.

Well there was no unit of measurement in my revision book anyway, so you should be grand!

QueenOfLeon

I thought it was grand, did all the short qs and experiments, and all the long qs except for the female reproductive one.
The bit above respiration was weird, at first i thought it was photosynthesis, but it wasnt....was it?
The fox was hilarious..."Foxes cant open bins!!"...Or something that sounded better than that :pac:
^^^ jammyc, i said something about the blind spot being in different places? Hopefully theres tons of reasons

Lol, didn't even know Lux was a unit of meaurement!

Thats what our teacher told us to write in! Maybe Im wrong though! Sure feck I wouldnt imagine theres too many marks riding on it.

It was pretty easy. I was shi*ing myself before I went in cause there was so much stuff I didn't know. The exam itself could have been much harder. I say I got around 80% overall.

And yea I said depth perception for the advantage of having 2 eyes.

celtic723

that fox question with the bins is going to have so many answers that will have to accepted. i'd say if you were correcting the exam you'd come across a few funny ones alright.:pac::pac:

What did yer graphs look like? I had light intensity on the x axis, number of bubbles on the y, so the graph started high and then dropped? But it wasnt a staight line, i wasnt really sure what to do with it....:o

Here actually, what the hell is that square thing called in ecology? I just called it "A square, .25m^2 in size"

Polarity

Quadrat

And uhm.. My graph started at the bottom left and went towards the top right.. levelled out about halfway there.

thats the way it goes except the right angled bit is curved.

Piste

^ Yeah that's how my graph looked too.

Quadrat?

Damn! Thanks, that was bugging me. Technically I didn't give an incorrect statement, so I should hopefully get most of the marks for that "How did you do the quantitative survey" question...

U MAD

thought it was good

didn't leave any blanks and was writing up until the last min

Thats what i wanted mine to be like, but couldnt see anyway i could manage it

The diagrams were a joke. The two letter V's in the eye were pointing at different things which stopped me from doing that question. And the arrows of the blood vessels in the section of the lung were barely distinguishable. Poor paper in comparison to previous years.

The two letter V's were the same thing...the iris AFAIK

agree with you though, I think Biology papers generally have very poor diagrams...

Wish i did question 11 it sounds so easy but i did everything else! Ugh glad its over tho.. Accountancy next and im a free man! What did people write for the rhysopus question for X? I said sexual reproduction i hope thats right

Yey, i said iris, but as far as i remember, 1 V was pointing to below the pupil, the other one was either pointing to the left or the right of that, either the cillary muscle or more like the front of the eye. I think The diagrams were bad quality anyway

I think it was digestion, as in the hypha digests outside the cell.

Then it asked what type of nutrition it had and I didn't know whether to put down extra cellular or heteretrophic so I put down both. Of course, that means if one if wrong it cancels out the other =/

Lucet

A total nightmare. In my mocks I got 70%, now I'm hoping for a pass. Only Q11 was ok. On others I used common sense and wrote a lot of stupid things .

It is possible to say that but I got the feeling of nutrition. The rhizodial hyphae produce enzymes which break down food and absorb the products of extra cellular digestion.

i said absorption for the rhizoid(X)

Well come correction time if that turns out to be a big problem any attempt will probably obtain full marks, that kind of thing is common in Biology

One year they asked you to draw a simple key and apparently the answers they got were ridiculous so any attempt at it got 100% of the marks, similarly same thing happened with a ridiculous genetics question..but then again genetics questions are ridiculous by their very nature
:rolleyes:

saphroptyic nutrition which is a form of heterotrophic nutrition

Very mixed reaction at my school.
I personally thought it was ok, hopefully got a c...didn't study the experiments, photosynthesis or respiration at all so well happy with the paper!
Ecology question was sexy...'what do foxes eat?' and the answer is on the page
Nice question on human reproduction, I was hoping for that!
