<p>Anybody here pulling an all-nighter?</p>
<p>I might stay up till 2. Hopefully not much later than that.</p>
<p>here is an extremely watered down version of answers
sumersinha: mendel theory. alleles seperate independantly during meiosis. i.e., two traits, tall and short, or green and yellow. yellow doesn’t influence tall, INDEPENDENT of each other. So applys to dihybrid or more crosses.
theundertaken: muscles have thin and thick fibers. Thick ones, myosin, attach to the thin ones, actin, and slide with the power of ATP. Occurs at sarcomeres, and contracts muscle. Muscles work in antagonistic pairs.</p>
<p>Piedpilko,</p>
<p>An all-nighter is a horrible idea, you wouldn’t be able to recall all the information you need when your sleepy.</p>
<p>@supergrover: first, systems are important, so read the ENTIRE animal physiology chapter in cliffs. It is good. second, DON’T stay up that late, you will FAIL. Studying anymore now is useless; you need a functional brain tomorrow.</p>
<p>I’m not pulling an all-nighter, I was just wondering if anyone was. (I’m going to bed now, 10:13 local time)</p>
<p>ughh. I guess I’ll take both of those advices (I’m aware that that’s not a word). I’ll go to bed at my normal bed time, which is 1:30 
(on school nights and weekends)</p>
<p>^lol supergrover, how do you do it?</p>
<p>And unfortunately, I still have to read through the systems 
I Understand digestive/excretory pretty ok right now, just really need to work on nervous/muscle…and the rest just screw them haha.</p>
<p>Alright. I saw the previous comment about muscle contraction. Tell me if this sounds correct:</p>
<p>Contraction is when Calcium Ions attach to the troponin, which are calcium sensitive areas attached to tropomyosin, which is connected to the actin. When calcium binds to the troponin, it unlocks the tropomyosin, allowing myofibrils to pull on the actin.</p>
<p>Would this be enough if an FRQ asked about the process?</p>
<p>I’d really appreciate it if someone could PM me some released exams? Possibly even 2002, please? Thanks!</p>
<p>I don’t know. I get a lot of work to do during the school year (I come home at 4, start my homework at 5, and usually work until 12:30-1:30). As I’ve gotten farther into the school year, I’ve gotten more and more school work, so my no-sleep tolerance has built up. lol</p>
<p>what grade year are you supergrover?</p>
<p>I am a junior - eleventh grade</p>
<p>no wonder, busiest year. what other ap’s are you taking?</p>
<p>I’ve taken Calc AB and APUSH, and wednesday I have AP English, so today’s my last day of really studying, and then I hope to coast my way to June (fingers crossed).</p>
<p>“and then I hope to coast my way to June”</p>
<p>–That’s kinda my policy…you know, except I started it in October or so. ;)</p>
<p>Heeey guuys, I’m running out of time to cram, but I am definitely not staying up all night. 1am at the latest… Are there any topics that show up a lot on the exam? And are there any that don’t really show up at all? I already studied the whole barrons book for sat2, so I feel like I have a base already, studying barrons AP just for everything else. But I still have 130 pages left… Is animal behavior and immune system important?</p>
<p>Also, about the labs, are there specific questions pertaining to a lab, or are they just general lab concept questions? </p>
<p>Thanks in advance!</p>
<p>Do you think we have to know about the kingdoms and phylums?</p>
<p>Hey guys, wondering if you all are studying examples of protista and such? In my 5 steps to a 5 book it says to know them but I don’t really want to go through the trouble of memorizing them all for a few multiple choice questions. Advice?</p>
<p>If anyone has the 2002 released exam can you pm me? thanks</p>
