Biology 2010 Prep

<p>O wow now don’t feel as bad in the beggining of the year our tests were like two chapters now they are five we hav so much too cover
is it me it was the first half of thr year more interesting? The 1st half was understanding how processes work and doing problems the 2nd half is all memorization!</p>

<p>1st half of the year covered respiration and photosynthesis and 2nd half covered evolution, plants, aminals, and ecology. I like the 2nd half better excluding plants.</p>

<p>I liked the first half better since it was mostly review.</p>

<p>Does anyone know if the practice tests in “5 steps to a 5” are comparable to the actual AP bio exams?</p>

<p>@homeschooling mom
Why not just get the 5 released exams online?</p>

<p>Here is a link providing access to one provided by the College Board:</p>

<p>Approximately 51 days remaining until the exam.</p>

<p>

</p>

<p>=(. </p>

<p>Kinda freaked out right now.</p>

<p>how do you grade that exam?</p>

<p>

</p>

<p>Multiple choice answers and FRQ scoring guidelines are listed on pages 31-40 of the PDF file posted in #246. </p>

<p>As for converting raw score to composite score, I will use the scoring instructions from Cliffs:</p>

<p>Multiple Choice: Multiply your raw score by 0.6 (be sure to subtract 1/4 of one point for each incorrect response with the exception of omissions)</p>

<p>Free Response: Multiply your raw score by 1.0</p>

<p>Then, add the two.</p>

<p>[ul][<em>]Raw Score to Composite Score Conversion
[list][li]61-100: 5[/li][</em>]47-60: 4
[<em>]39-46: 3
[</em>]30-38: 2
[*]0-29: 1[/ul][/list]</p>

<p>Whats the difference between NAD and FAD?</p>

<p>Holy cow. I realized that I actually forgot most of that. I’m quite good at Biology but maybe my retention is bad now. I haven’t studied for the exam much using Cliffs; do you think I should even though the exam doesn’t matter a whole lot to me?</p>

<p>How did you do mifune? I wouldn’t be surprised if you answered 90% +. As for the others, when you quickly glanced at the exam and did a few questions were you acing them all?</p>

<p>This worries me! AHH</p>

<p>Both function as high-energy electron acceptors within metabolic pathways. However, FAD consists mostly of riboflavin, whereas NAD is composed mostly of nicotinamide.</p>

<p>Describe the differences between organisms classified in the domain of archaea and organisms classified within bacteria.</p>

<p>Lots of people have asked me for past released AP Biology tests. I thought I’d help out by uploading and posting it here. </p>

<p>Thanks Xcellerator!!! My AP teacher took the test in 1994 i believe and it will be interesting to see if I can get a 5 same as him.</p>

<p>i’m deciding whether to buy cliffs… I have barron’s and have been going through it. does anyone have both and think its worth it to switch to cliffs (or supplement one with the other)?</p>

<p>

</p>

<p>I actually haven’t taken the exam I posted yet.</p>

<p>

<p>Organisms classified within the Domain Bacteria are often pathogenic (disease-causing) and it includes viruses since this category provides them with the most suitable outlet.</p>

<p>Organisms identified within the Domain Archaea include extremophiles, those that persist in harsh environments. These include halophiles (thrive in saline conditions – such as the Dead Sea or Great Salt Lake), thermophiles (flourish at very high, abnormal temperatures), and methanogens (those that produce energy by converting hydrogen to methane).</p>

<p>At the molecular level, the most conspicuous difference between the two is the presence of the cellular wall component peptidoglycan in bacteria while it is characteristically absent in archaea.</p>

<p>

<p>I would advise that you use Barron’s since that will provide you with ample study material. Barron’s appears to uniformly produce high-quality products for AP exam preparation. Purchasing Cliffs would most likely be redundant.</p>

<p>Thank you for posting the exams, Xcellerator!</p>

<p>Describe the hardy-Weinberg principle.</p>
