<p>This doesn’t look like a good question, but I would guess that the lion needs to learn where its prey is and other variables such has how tired the prey is/its surroundings, while the baby would grasp something placed in its hand every time so choice e would be closer to the idea of a fixed action pattern.</p>
<p>A lion would have to learn to hunt for prey from its parents/pride members. Who teaches a baby to hold something in its hand? No one.</p>
<p>The palmar grasp is a reflex babies have from birth. No learning at all. Funny, I actually learned that in AP Psychology.</p>

Wow, I didn’t think of that. I’m stupid (I’ve taken a few bio and psych classes).</p>
<p>It is definitely E. lol</p>
<p>Which study guide is better for bio, Barrons or Princeton Review?</p>
<p>neither, cliffnotes</p>
<p>Princeton Review is pretty good, thats what I’m using.</p>
<p>What i’m doing:
reviewing AP 5 Steps…you only need 60% on MC to get a 5, so i’m making flash cards for the quick reviews at the end of every chapter after reading it through carefully & highlighting
then i’m also doing as many practice tests as possible, and making flash cards for the one i missed
i heard from a friend the AP exam only has so much info…they’ll def repeat questions/reword them if they’re not on the test exactly:)</p>
<p>gl everyone!</p>
<p>folks. I’m solving released FRQs now and I’m getting stuff (I’m correcting these by myself using the scoring guidelines) like 37 and 39 of 40!!! I mean how?? I see people who get a 5 get 25 or something in the FRQ. I feel like I’m maybe correcting them wrong or somthing. Does anybody know any way to kinda check on the integrity of the mark i give myself? I mean the ap psych frqs were super easy to score. the biology ones are hell, however… what do u guys do when correcting ur own frqs?</p>
<p>@jasonjackson789
you probably are getting all the points…nice job…i know it’s weird but you really don’t need to write everything to get all the points. for each part there are like 4 points possible but like eight different ways to get the 4 points. i just can’t remember all the details so im stuck around 25 still 
sill practicing though…</p>
<p>well, u kind of relieved me by that 
thanks. the best thing is to use the old frqs coz they’re really the key. I’m so tensed about this exam! good luck!</p>
<p>guys, i nedd some help with this question it’s no. 45 in the first practice exam in cliffs:</p>
<p>Which of the following is the dominant reaction as
blood flows through the pulmonary capillaries?
(Hb = hemoglobin)
A. H2CO3 → H+ + HCO3
B. H2O + CO2 → H2CO3
C. Hb + 4CO2 → Hb(CO2)4
D. Hb(O2)4 → Hb + 4O2
E. Hb + 4O2 → Hb(O2)4</p>
<p>I don’t get it at all? can somebody please elucidate it for me? thanks!</p>
<p>I think the answer’s E because it’s the hemoglobin reaction–oxygen diffuses through the capillaries in the lungs (pulmonary capillaries) and is accepted by hemoglobin. Thus, the formula that depicts the uptake of oxygen by hemoglobin the correct answer</p>
<p>E looks correct, as explained by bwblue</p>
<p>Agree with bwblue</p>
<p>Maybe the answer is in this thread somewhere, but it is rather long… I had thought that they no longer deduct .25 for incorrect answers. But then today I took one of Cliffs practice tests (from the 3rd ed review book), and in the scoring section it says to subtract the # wrong from the # correct 
!! Not even .25??? …do they actually do that? Does collegeboard have posted somewhere how they score all the different AP tests? Do they score them all the same (with regards to subtracting for wrong answers)?</p>
<p>Please if you answer have a source if possible; I don’t want to risk my AP grade!</p>
<p>Thank you for any info!</p>
<p>ok guys, i figured the answer out. i forgot to put the answer. it’s E. thanks! I do have another question, though. it’s number 75 in the same practice test: <a href=“http://i49.■■■■■■■.com/2hedqb5.jpg[/url]”>http://i49.■■■■■■■.com/2hedqb5.jpg</a></p>

<p>The answer is B. Why is B wrong? the explanation says it is at equilibrium at 14 minutes. i don’t get this.</p>
<p>equilibrium doesn’t mean equal concentrations. it means that the reactions have gotten to a certain rate so that it seems like nothing is happening anymore (in other words, net change is zero). at 4 min, the concentrations are equal but not at equilibrium. they’re at equilibrium at 14 min because the concentrations seem like they stop changing from that point on.</p>

good luck to u too</p>

I know for a fact that the AP no longer deducts for incorrect multiple choice scores. Your cliff’s might have been out of date. (they have only stopped deducting for only like 2 years though)</p>
