Biology 2010 Prep

<p>I predict everything I haven’t studied will be on the FR section, how about you guys?
Back to the nervous system in the meantime…</p>

<p>isn’t that 2008 version(practice) the audit? or is that the actual released?</p>

<p>If anyone’s having trouble with flower reproductive organs… staMEN, filaMENt all have “men” in it, so you know they are male reproductive organs. For females, stigMA has “ma” in it, like a mother. Just throwing that out there. (I also said women had STYLE)</p>

<p>^I’ve got the organs down, but not the hormones…Someone explain plant and animal hormones to me…</p>

<p>cytokinins: youth fountains: help stop the effects of ethylene
ethylene: aging of the fruit
Auxin: basically everything: elongation</p>

<p>the others i have trouble with.</p>

<p>what do you mean by percent btw? like out of 100 for cliffs? cuz i basically do perfectly on FRQ and get only like 40 points out of 60 for MC.</p>

<p>Not including the FRQ</p>

<p>can someone explain to me alternation of generations? what’s it mean</p>

<p>so if you say you got 50 percent on MC on ciffs you mean you only got 50 out of 100 right?</p>

<p>Yes… In my defense I haven’t finished the book and was taught nothing in school lol</p>

<p>the cliffnotes test is a lot easier once you finish the book</p>

<p>hahaha that makes me feel ALOT better. and cliffs is ALOT harder than the released exams id say… some weird questions.</p>

<p>^^ i would hope so</p>

<p>

Actually, that’s the 2008 audit exam… not the released. :)</p>

<p>

No, it wasn’t hard at all. It’s the first released exam I took and I was surprised at how simple it was. And yes, it’s the one with the really huge curve.</p>

<p>I just took the 1994 released exam. After calculating my raw score, then converting it to a 100-point scale (instead of the 120-point scale), I got a 64.6. That seems to be my average, considering the three released exams I’ve taken (2008, 2002, 1994). Tomorrow morning I’m going to take the 1999 exam and try some released FRQs to simulate the actual test, and see how I did. :)</p>

<p>For the guy several posts above, the Alternation of Generations (doing this from memory, please correct if any errors):</p>

<pre><code> Plants reproduce in a cycle called the alternation of generations, in which the gametophyte (n) and sporophyte (2n) forms alternate. Generally, this means at one time the plant in question will be haploid (n), and is called the gametophyte, and then that produces the sporophyte (diploid plant) through sexual reproduction (the gametes were formed by mitosis). The sporophyte then produces the gametophyte through meiosis.
In many plant species, one form is dominant over the other. In tracheophytes (plants with vascular tissue), the sporophyte is generally dominant, while in bryophytes (plants without vascular tissue), the gametophyte is generally dominant. In ferns, for example (tracheophytes), the sporophyte form of the plant is the only part you actually see; the gametophyte is small and easily overlooked.
That’s a basic overview, correct as you see fit.

<p>Does anyone know how important the 12 labs actually are?</p>

<p>Guess: one of the essays will be about muscle contraction (or at least one MCQ) :)</p>

<p>i hate muscle contraction… so much</p>

<p>[Khan</a> Academy: Natural Selection and the Owl Butterfly](<a href=“http://khanexercises.appspot.com/video?v=dR_BFmDMRaI]Khan”>http://khanexercises.appspot.com/video?v=dR_BFmDMRaI) < Very useful studying material.</p>

<p>I can’t stand the guy in the videos… but I guess I’ll have to put up with it if I want to learn anything. :p</p>

<p>the labs are VERY important</p>

<p>get to know them well</p>
