<p>really? would it be “a terrible loss for science” if some students chose chemistry over biology?</p>
<p>I agree that Molecular Biology is one of the most fascinating subjects for somebody with a Bio/Chem mindset.</p>
<p>p.s. I am a molecular biologist myself</p>
<p>Ok! That was probably a little exaggeration. There is still a misconception that Biology is all about memorization and it is very boring. You can memorize Campbell and Reece cover to cover and still have trouble answering USABO questions. The kind of problem solving skills needed for AMCs or USACHO is needed for Biology as well.
Whether you choose to do Math, Physics or chemistry there is a good chance that you will end up using that knowledge and skills to solve a Biological problem. The way research is going you cannot compartmentalize these by rigid definitions. That’s all.</p>
<p>I like Chemistry as well and thanks for the link.</p>
<p>There’s no shortage of biology majors… if anything there are too many.</p>
<p>Hi, can anyone please send me any spare USABO tests other than the ones from 2004 and 2006? If so, I would be very grateful!
Sorry, I know cc’ers don’t like others who ask this, it’s just that I’m a rising freshman and I want to get all the practice I can to prepare for the USABO, I hope I make Semi-Finals in 9th grade :/</p>
<p>Hey everyone, a rising junior here who is quite excited for next years USABO/IBO, just about finished my school year and ready to start studying for next year. Congratulations on all those who have made it to camp, quite an accomplishment. I was wondering if anyone could explain to me this problem that was on a past IBO test. Thank you, in advance. </p>
<p>A yeast extract contains all the enzymes required for alcohol production.
incubated under anaerobic conditions in 1 liter of medium containing: 200 mM glucose, 20 mM ADP, 40 mM ATP, 2 mM NADH, 2 mM NAD+ and 20 mM Pi (inorganic phosphates). Ethanol production can be summarized by the following equation:
C6H12O6 2 C2H5OH + 2 CO2 + 2ATP
What is the maximum amount of ethanol that can be produced under these conditions?
A. 2 mM
B. 20 mM
C. 40 mM
D. 200 mM
E. 400 mM</p>
<p>I know the answer is B, however is it found through stoichometric ratios or conservation of mass? or neither? haha!</p>
<p>Is the depth at which organ systems are covered in campbell and Reece suffice or is there any another human anatomy and physiology textbook? </p>
<p>Does anyone recommend Molecular Biology of the Gene by Watson?</p>
<p>OK, for anyone who I have not yet sent old exams to, please send me an IM with your email addy and I will forward them to you.</p>
<p>I am doing this as to hope that you guys don’t use them for trading next year. The exams should be open to everyone (through CEE).</p>
<p>@Polish</p>
<p>Stoichometric ratios. It’s moles :P</p>
<p>@Opinion</p>
<p>They handed out some A&P book at finals this year. Don’t remember the author and they didn’t give me a copy :P. </p>
<p>I’ve never seen Molecular Biology of the Gene before - I’ll see if I can get my hands on a copy. </p>
<p>@ChemTutor</p>
<p>Can’t judge USABO from IBO, unfortunately. Lowest scoring member on our team last year (cough me cough) got 7th in Internationals. Our exams are way harder than the IBO exams :P</p>
<p>@Jason</p>
<p>You’re asking questions about info that you basically just have to memorize:</p>
<p>
</li>
</ul>
<p>The glomerulus has a capillary bed so it can filter properly and then the blood continues on to the rest of the nephron so the filtrate can be properly processed. Hypothalamus uses a double capillary bed circuit to more directly talk to anterior pituitary. And liver’s in a double so it can get to the blood that comes from the intestines first and get rid of toxins/restore homeostatsis.</p>
<p>
</p>
<p>Agree with your explanation.</p>
<p>
</p>
<p>B’s backwards, in the pulmonary capillaries, you’re giving off CO2.</p>
<p>Re: Parasites. Read the question again - it’s not laying eggs on the warbler, it’s laying eggs in the warbler’s nest. </p>
<p>Re: 89 “Null H” is always the statistically nothing happens result, basically. A attributes this to control over the experiment, which may not be the case.</p>
<p>aka A assumes you know things, while E says this is what we expect. Or something like that, it’s 2 AM here :P</p>
<p>re: 75 it’s C because 2->3 shifted real fast.</p>
<p>and I think 76 is D because it’s slowly shifting.</p>
<p>@ImSoAmbitious </p>
<p>your library is better than mine :P</p>
<p>Start with Campbell. Memorize that. Then go to Raven’s Plants. And memorize that. And if you have time, skim Alberts, Lodish, Voets, Lehninger. But those are real low priority.</p>
<p>@all</p>
<p>And I’m not sure how many peeps get contacted but I’m pretty sure that I was “waitlisted” in 2010 because I got the email (and a call!) really late. Not sure, and I dunno Mrs. Frame will answer if I ask her.</p>
<p>@cadaeibfed</p>
<p>
</p>
<p>May I remind you that we beasted China? Heh. China teaches it’s team to memorize everything perfectly, we teach ours to BS their way through everything. </p>
<p>@biofreak21</p>
<p>Glancing over the links can’t hurt.</p>

<p>I’m in college now. Haven’t seen this year’s open, probably never will. Heh. Would love to know if any of my Q’s made it in. Probably not. Sleep-depped me makes bad questions.</p>
<p>@everyone</p>
<p>If you find a Q that you think is badly worded, feel free to shoot it to me in a PM, but you’re probably best off contacting CEE yourself. They do tend to be reasonable.</p>
<p>@NightShadeQueen:</p>
<p>Thanks for looking into A & P test books. In your book list you have Lodish, & Lehninger. What are the names of the textbooks? I have never heard of these authors before.</p>
<p>@NightShadeQueen: any opinions on these two books?</p>
<p>Life: The Science of Biology (6th Edition)
<p>O.O NSQ, I’m officially your fan!
It’s so awesome you made it to IBO!!!</p>
<p>@Opinion:</p>
<p>Lodish: Molecular Cell Biology
Lehninger: Principles of Biochemistry</p>
<p>As for the others, I’ve never heard of them. Maybe blueroses’ll show up again and give you an opinion. I can track them down to take a look when I get back to campus on the 17th.</p>
<p>I’ve never read a genetics textbook, but I did browse the MIT OCW archive. Try looking through old 7.03 exams.</p>
<p>@MathGuy</p>
<p>Heh thanks 
Good luck yourself :D</p>
<p>@Everyone who wants old semis/finals from me.</p>
<p>I don’t have any. Yeah. I know. Didn’t use them, never used them. Yes it’s unfair and obnoxious that CEE isn’t releasing old exams, but I don’t have any old exams, period. Hell, I don’t even have the semis I took anymore due to a massive fail at installing Ubuntu that corrupted my HD.</p>
<p>However, old semis might become available from CEE soon. Hopefully. :P</p>
<p>Old open exams should be available from your biology teacher.</p>
<p>Re: Editions of Campbell - stick to 7e or later. I haven’t had time to fully look through the 9th, although there’s at least one point where it adds info instead of taking it out :P</p>
<p>O.O
YOU REPLIED TO ME!
I’m officially happy now
Sorry if I sound creepy…</p>
<p>@NightShadeQueen:</p>
<p>Thank you so much. I do hope CEE will release the semis. Otherwise it will be so unfair esp. since some have it and some some don’t.</p>
<p>I don’t see any big difference between Campbell 8th and 9th editions.</p>
<p>Hello everyone, I am a rising junior and I highly interested in taking part in the Biology Olympiad next year. Could anyone give me some advice? I am mainly using the Biology 8th Edition Campbell and Reece. I know that reading through the book multiple times will not guarantee me a successful chance in competing; however, how can I systematically study and prepare for the USABO next year. Thanks for your help.</p>
<p>@Opinion</p>
<p>So apparently EL (IBO 2010) likes Purves.</p>
<p>And as for old exams, yeah, that’s what I want too, but there’s not much I can do 'xcept write more questions, and apparently I can be a real ******bag when writing questions. Grr. :P</p>
<p>And I doubt there’s much difference between Campbell 8th and 9th. CV(“Blue”) swears that the 7th is the last real edition of Campbell, though, since it’s apparently the last one the guy worked on before he died :(. It’s <i>Campbell Biology</i> by Reece, now.</p>
<p>@MathGuy </p>
<p>heh so does this explain the fangirling yesterday?</p>
<p>@bobjohnson</p>
<p>Know your charts. All of the charts in Campbell are fair game for questions on every level of the test.</p>
<p>Stick with Campbell for the Open - you shouldn’t need more than that :D</p>
<p>Hey NSQ, how did your first year at MIT go? Quick question: do IBO’ers like yourself place into advanced/grad courses in biology early on? Or do you just take the regular classes and ace them with ease?</p>
<p>@Studious:</p>
<p>Pretty well, thanks. </p>
<p>I ASEd out of 7.01x and then did a 180 and went off to study physics, haha.</p>
<p>Also - some peeps were asking about my notes: Here they are <a href=“http://db.tt/Rwoiy1O[/url]”>http://db.tt/Rwoiy1O</a> they’ll be in my dropbox forever :D</p>
<p>Are these notes for USABO or AP? And what is an IBO’er?</p>
<p>they’re technically for TAMS’s bio class, haha, but I used for USABO.</p>
<p>and IBO = International Biology Olympiad ;D</p>
