<p>Okay so back to FRQ #2 from the practice test. Why does the rate of water movement become a limiting factor? And why is transpiration limited by humidity?</p>
<p>Thanks!</p>
<p>to be specific protein hormones could be also called peptide hormones</p>
<p>For at least the second part of your question, jadenio:</p>
<p>Water moves from high to low water potential. The less of a differential between the leaves and the air, the less water will transpire. More humidity means more water content in the air, which means transpiration will decrease. This is the opposite of using something like a fan on the leaves, which essentially decreases humidity and creates a larger difference in water potential for transpiration to occur.</p>
<p>I’m not sure about that info. but I am restricted to telling the stuff people have requested because the CB policy states that I am to not discuss the details of the exam. As much as I want to tell you and all the people here what’s on the test I really can’t. I guess the only thing I CAN do is to wish you and all the people going to take the test good luck on the exam.</p>
<p>Did anyone else feel the Barrons test were awful? I’m so resigned at the moment.</p>
<p>Surely you can tell us if you thought the damn thing was hard, right? That’s not exactly a detail or specific…</p>
<p>@teekskim I’m not sure the exact guidelines, so unless you know day anything, but check to see if you’re able to mention general thoughts about the test. Was it similar to the practice test offered by CB, was a lot of detailed required, and were the concepts straightforward if you know the course really well.
As these are not exact details, you may or may not be able to answer these questions, if so please write, if not, then don’t risk anything by writing.</p>
<p>Can you at least give us some topic areas for the FRQ @teekskim…i will love you for ever :)</p>
<p>It’s most likely a different test he took, the most information he can supply us that will help is how similar is it to the practice test. If yes then we’re on the right track, if no then…
Because the practice test pretty much covers all the topics, just they’ll be asked from a different persepectives or with the focus on a different topic.</p>
<p>Do you guys think that the FRQs will be similar to previous years?? Should I study past years’ frq???</p>
<p>It’s 10:50, the exam’s tomorrow and I didn’t study this entire weekend. Oh well. Good night and good luck everyone</p>
<p>My ap bio teacher says that we get points for correct answers and if the info is wrong then it is disregarded. So of we werent sure for an essay topic we can just put everything we know about that topic an have the grader accept only the right answers within our essays. Any truth to this?</p>
<p>^ Yes, you don’t get penalty for wrong answers in the free response section in ALL math & science exams( physics, chem, bio,…)So just put down everything you know.</p>
<p>does anyone have a good cram sheet/packet?</p>
<p>Good luck fellow AP Biology-ers. </p>
<p>And may the odds be ever in our favor.</p>
<p>was it just me or were the grid ins way too easy… especially the hardy weinberg one where you just square the p or q whatever allele it was…</p>
<p>and no spoilers here… but what did you guys do for the first grid in… phenotypic female… probability of…</p>
<p>frqs were much harder… i was especially confused at how to answer the function of the cell types and the “processes” of the co2 cycle bit</p>
<p>@magmar95</p>
<p>I totally agree. The grid ins were way too simple.</p>
<p>I was stumped on the 2nd FRQ. What did you put for it?</p>
<p>2nd frq was the one with the wavelengths of light right? Wasn’t that one straightforward? We might have different forms</p>
<p>I totally blanked on it, and I think I messed it up.
My 1st FRQ asked about the CO2 cycle, so I think we had the same forms.</p>
<p>I think I screwed up the 4th FRQ though. I left it blank cause I ran out of time…</p>
