<p>Ok, so just a question…
Did anyone struggle with some of the released tests from previous years, and then end up doing really well on the national test?</p>
<p>*Protista are hardly ever mentioned on the national exam, as I’ve heard from many people on cc</p>
<p>There was actually a past essay question on different animal behavior/learning processes. Here are some more in-depth examples. They’re also more interesting than carrot digestion haha.</p>
<p>Operant learning/Trial and error - Pretty self explanatory; Birds know how to improvise/fine tune their song to attract mates based on response/nonresponse to their singing</p>
<p>Habituation - a snail will retract into its shell in response to being touched by a probe. However, continued touching by a probe will cause the snail to become habituated and eventually the snail will stop retracting into its shell</p>
<p>Imprinting - When organisms learn during a “critical period,” often during the beginning of their development. Example: Greylag goslings followed researcher Lorenz because they saw him before they saw their mother, so they imprinted on him (treating him like their “mother”) and followed him wherever he went, rejecting all other organisms including their actual mother</p>
<p>Association - Pavlov’s dogs is a great example. He noted that dogs salivated when he fed them. He conducted studies where he would ring a bell before feeding them, so eventually they associated the bell’s ring with food and would salivate just by hearing the bell alone.</p>
<p>Fixed Action Pattern (FAP): As noted in past post. Example would be red-bellied stickleback fish whose bellies turn red during the breeding season; their FAP is natural aggression towards other red-bellied stickleback fish; however, anything that is red will trigger this FAP, so they will attack anything red, not just when they see the red belly of an actual fish</p>
<p>Out of curiosity how much do we need to know about ecology. When I was reviewing it seems pretty simplified, like population growth, limiting factors, etc. Behaviors like commenalism, mutualism, parasitism, competition, and predation. If there is something that you think that should be added please post.</p>
<p>hey guys. Since we have only today and tomorrow before the test i was wondering whether it would be better for me to take the 2002 test or cliffs/barrons instead. Which one would be more worth my time?</p>
<p>I would have to say 2002 since it will actually be like real test questions rather than a Cliff’s or Barron’s made test.</p>
<p>Anyone have the 2002 test on their computer? I really need that sheet.</p>
<p>^ sorry i dont have it on my computer, but im sure you’ll easily be able to find it somewhere on CC. I think…</p>
<p>Ok to continue our thread
i haz question:
What is the direct result of the krebs cycle?</p>
<p>^ the kerbs cycle creates 3 NADH, 1 FADH2, 1 ATP, 1 CO2</p>
<p>MY questions is if we need to memorize the kreb and calvin cycles? I am talking about knowing the steps of these cycles</p>
<p>meh…i dont think its very specific, nore concept based and comprehension, so the straight facts you need to know are the basic ones</p>
<p>I would (and did) just in case it comes on the FRQ</p>
<p>Do essay topics repeat in consecutive years or they’re always different from each other every year?</p>
<p>You definitely don’t need to memorize all the steps. They award points very liberally and you can earn points in many ways so memorizing individual steps will take up space and time. Instead you could learn about something else. Also you don’t have too much time to write a detailed 5-paragraph essay during the test. Another point is that each sub-section is only worth a few points so not too big of a deal.</p>
<p>its virtually impossibleto get a10 on the frq so as long as you understand it and know key terms thats all that matters. they DONT take off points for rambling unless you contradict yourself, but you get a point for each key term/concept you mention. so if you can sum up the whole frq in half a page, you can still do much better than someone who writes 3 pages of bs</p>
<p>@Black, just look up all of the past FRQ’s on collegeboard and you can answer than yourself.</p>
<p>Lol, I’m reading through my bio review book from princeton review and I
m not of laughing. So I’m looking at the plant reproductive cycle, and it says “Fortunately you don’t have to know all the details of this process, all you need to know is bryophytes the gametophayte gen. is dominant and in tracheophytes the sporophyte gen. is dominant” Lol the 2008 FRQs</p>
<p>epic fail.</p>
<p>mast cells release histamine. something something, blood clotting, platelets come through by blood since the histamine sends out signals. something like that, i forgot.</p>
<p>another question:
in what specificc phase does DNA replicate in mitosis</p>
<p>personally, i thought that the plant reproduction frq was the easiest of the four from last year…</p>
<p>I was looking for </p>
<p>Thrombinplasin + Ca + Prothrombin ==> Prothrombin stimulates fibrilogens which create fibrils which clot.</p>
<p>^***???/ i never heard of that T_T</p>
