<p>Can anyone make an educated guess about what they will be? I looked at last year's and they were all about the things I didn't know (pland reproductive systems, chromosome sturcture, and immune system). If they are about, for example, photosynthesis or cellular respiration, medelivain genetics, or the digestive or circulatory sytems, I'm in really good shape. I'm hoping that since those questions were on the test last year, they won't be this year.</p>
<p>my teacher predicted either transpiration or the blood pressure lab for the lab component</p>
<p>transpiration or animal behavior
meiosis/mitosis lab</p>
<p>What is the end of lab 3 about? Does anyone know?</p>
<p>there will be one cellular, one evolutionary or genetics, and 2 on organisms/populations per collegeboard's description. i'm betting the lab question will be over lab 2, 6, or 9, leaning more towards 2 and six (they fit right into the molecular niche). then evolution/genetics will probably be some BS with punnent squares, you know the usual. for the last two i say one heavy on ecology, like a graph you have to interpret, and one about a human/vertebrate system (i hope to god it isn't about plants, i hate plants).</p>
<p>plants will kill me... or hormones... based on practice tests i need 50% on the essays to get a 4.. which would be really nice.... please no plants....</p>
<p>something about crossing over, english? </p>
<p>I dont know, i left my lab book in my locker ;(</p>
<p>BD> Ridiculously specific. If those predictions are right remind me to buy you lunch if you ever happen to stroll into NYC.</p>
<p>BD,</p>
<p>BS about punnet squares??? Does this mean we need to be able to know how to solve the 16 square/dihybrid cross . . . i know the supposed outcomes but don't know how exactly to solve one, anyone know???</p>
<p>lab 2 was already tested on, I don't think it will be about that.</p>
<p>sarorah> At least you have your lab book, I lost mine the end of first semester and never got myself a new one. Thus my low lab grades heh.</p>
<p>You may want to break the various parts down. Say they ask the probabilities of having XXYYZZ from XxYyZz x XxYyZz. Then the probability of XX is 1/4 probability of YY is 1/4 and probability of ZZ is 1/4. (1/4)^3 will be your answer.</p>
<p>lol, but it's not helping me right now, plus I used a girl's labs from last year (she got a 5, but it's not going to help me now) :(</p>
<p>I still have to read the chapter summaring the labs in cliffs. . .</p>
<p>Yea thats all I have done today. Still need to do the labs, Animal structures, ecology, and briefly glance over respiration/photosynthesis. I am hoping to god that genetics is emphasized.</p>
<p>Ohh...yeah, breakign it down, but lets say you have something like </p>
<p>For the cross AABBCCDd x AAbbCcDd, what is the probability that an offspring will be AABbCcDd?</p>
<p>.............no idea.</p>
<p>Lol, nice posting responses we have.</p>
<p>I need to find a short summary for the DNA replication stuff, and the plant photosynthesis/C4/CAM, CELLULAR RESPIRATION specifics, along with animal structures too :(</p>
<p>Do the following: Do a punnet square for AA and AA (1) do one for BB and bb (1) do one for CC and Cc (1/2) and one for Dd and Dd (1/2). So 1<em>1</em>.5*.5 is your answer.</p>
<p>Anyone up for the chat again? ahaha</p>
<p>Sarorah> Use Cliffs. I am guessing you mean molecular genetics? The chapter in cliffs is awesome.</p>
<p>are they really gonna make you do a punnett square for FOUR types of genes? that seems unusually cruel XD</p>
<p>I doubt they would ask you for a straight up punnett. More like probability of something happening in which case you can break down and do them easily.</p>
