<p>I doubt you guys will get chi-square. It takes too long to calculate and all it really shows is that you can do math, not biology. You may be asked to discuss the purpose of running a chi-square analysis, though, if you get any FRQ about breeding organisms. I’d just brush up on the definition and leave it at that.</p>
<p>The Barrons review book had a study hint that said if they do an evolution frq it’s usually coupled with an ecology part as well. Ecology is simple though, so don’t worry! </p>
<p>I would know the difference between like primary and secondary succession though… things like that</p>
<p>Oh, my suggestion for all of you who want to relax today (but not slack off): watch Avatar. Think of everything in the movie in terms of biology. The guy is an idential twin, so he can use his brother’s Avatar - what does that mean about their DNA, and about their embryonic development? When they’re collecting samples from the tree and the lady goes “There is signal transduction going on between the roots of the trees!” what does that mean?</p>
<p>And so on, and so on :)</p>
<p>maybe don’t start relaxing until tonight; we still have a whole almost 20 hours…</p>
<p>How much should we know about embryonic development stuff?</p>
<p>@dylandlima, yeah, I just checked the 2010 FRQs, and there was one about cell signaling with hormones, but cell signaling is pretty universal and could easily show up again this year</p>
<p>What is the relationship between the thyroid gland and the adrenal medulla?</p>
<p>Where can I get a complete rundown of DNA stuff? like Translation, transcription, protein manufacturing and all that? I am CLUELESS about it!</p>
<p>From what I remember in class, chi-squares are pretty complicated topics. I doubt they will show up on the FRQs since they require a fair amount of math to figure out. That being said, Hardy-Weinberg problems are much more likely to be asked.</p>
<p>If I had time to focus on one thing, what should I look at first?</p>
<p>@ nervousjim</p>
<p>Plants!</p>
<p>@ronaldofan94
Eww plants. Lol. Ima fail lol</p>
<p>Plants were my favorite part! It wasn’t too hard and it’s really fascinating!</p>
<p>Repost:
I don’t know if anyone else heard about this, but my teacher told me that collegeboard stopped doing Chi-squared analysis for their labs starting awhile ago. Can anyone confirm this? Thanks. (My teacher has taught for 35+ years)</p>
<p>@ sinohellenic the thyroid and the adrenal medulla work somewhat antagonistically of one another. the Adrenal medulla stimulates your fight or flight response by releasing epinephrine and norepinephrine, and works with the sympathetic nervous system. the thyroid releases thyroxine, which controls your metabolic rate and is more parasympthatic nervous system related i think. Probably wrong with all i know about hormones</p>
<p>Nah, last year’s bio class from my school apparently saw Chi-square on their test and was like O_O what is this</p>
<p>@ranaldofan94 and urc</p>
<p>Chi-squared has been a free response question in the past, and could likely show up. It isn’t too difficult to remember either. (o-e)^2/e. If they ask it in the FRQ, they will give you numbers that are easy to calculate in your head.</p>
<p>I’m a fairly good student; I have had a solid A in AP Biology all year. How well do I need to do on the multiple choice, in terms of percent correct, and the FRQs to get a 4? or maybe even a 5?</p>
<p>I know there is a “curve,” but I’m not sure how exactly this works. This is my first year with AP classes (taking gov’t, econ, bio, english comp).</p>
