ibnerdcando Posted May 10, 2014 Report Share Posted May 10, 2014 How'd you guys find the SL Biology Paper 1 and 2? I personally found paper 1 to be worst than paper 2.......should have read more clearly!! Definitely more confident about paper 2..esp section B!

IB . Posted May 10, 2014 Report Share Posted May 10, 2014 Hey!I found paper 1 to be pretty easy with a few sneaky questions.What did you guys get for the multiple choice questions asking about:- what causes gene mutation- where action potential occursAs for Paper 2, I thought it wasn't bad at all! I choose 5. for section B cause it was stuff from topic 3.I was surprised that there was barely anything for topic 5! Reply Link to post Share on other sites More sharing options...
ibnerdcando Posted May 10, 2014 Author Report Share Posted May 10, 2014 Agree, paper 1 had tricky questions. I actually don't remember my answer to those two But for the last question I totally messed it up about normal male I chose D when it was B ...ughhhhh Reply Link to post Share on other sites More sharing options...
IB . Posted May 10, 2014 Report Share Posted May 10, 2014 I thought it was D becuase you need X and Y chromosome plus testosterone for pre-natal development of male genitalia 1 Reply Link to post Share on other sites More sharing options...
ibnerdcando Posted May 10, 2014 Author Report Share Posted May 10, 2014 Thats what I thought im actually not even sure but the smartest guy in our class said something about the question being tricky not asking about the whole male human body but a specific part of it being normal i dont remember the question 100% 1 Reply Link to post Share on other sites More sharing options...
IB . Posted May 10, 2014 Report Share Posted May 10, 2014 No trust me, it's D. I'm 99.9% sure. Let's find out when more people reply and comment. 1 Reply Link to post Share on other sites More sharing options...
kobe24 Posted May 10, 2014 Report Share Posted May 10, 2014 Male development was D. Action potential was anywhere on cell membrane. Gene mutation was allele change. 1 Reply Link to post Share on other sites More sharing options...
IB . Posted May 10, 2014 Report Share Posted May 10, 2014 Hey kobe 24, do you remember specifically what the gene mutation question was? I got everything you got except the allele change. I said crossing over... :/ Reply Link to post Share on other sites More sharing options...
kobe24 Posted May 10, 2014 Report Share Posted May 10, 2014 'which of these occurs during/in gene mutation', or something to that effect 1 Reply Link to post Share on other sites More sharing options...
Hfdf Posted May 10, 2014 Report Share Posted May 10, 2014 Ok guys help! What did you put for the question that talked about "describe the relationship between surface to volume ratio..." i put that surface area increased as the cell increased but at a much slower rate than volume, thus making the cell be limited in size. then i said that it needed less surface area than volume in order to give time the cell to exchange waste materials and take in other...what about ratio genotypes and phenotypes?!?! it knocked me off that question, since when phenotypes have ratios? phenotype is the overall characteristic/trait of that organism, how can i give a symbolic representation for that? i really got confused!magnification no idea... what size did you got for the micrometer? i got 8.2um (lol but not too sure).im really scared because section a was kind of **** (i also got the phyla wrong), but section b was fine (i did trophic levels)how was it for u guys??

And was the surface area to volume question in section A? Reply Link to post Share on other sites More sharing options...
DutchStudent94 Posted May 11, 2014 Report Share Posted May 11, 2014 For paper 1, what was the favourable variation that could become less favourable??A lot of people said Climate Change, but to me the only logical answer seemed to be Overpopulation. (p.s. about the magnification, pretty sure that it was 5000) Reply Link to post Share on other sites More sharing options...

(p.s. about the magnification, pretty sure that it was 5000)ok so i got the magnification wrong obv never understood it hahahi've put climate change! overpopulation would be seen as 'competition' and favourable variation would give advantages to the overproduction of offspring... so the only thing that could make a favourable variation less favourable would be something abiotic... but i don't know i can't be 100% sure, this is the problem with abcd exams they can be so tricky!Ok guys help!

IB . Posted May 11, 2014 Report Share Posted May 11, 2014 Oh, well I'm talking about TZ1 But what you said about surface area to volume ratio sounds right! So hopefully you get all the marks you want! Reply Link to post Share on other sites More sharing options...
