<p>My idea is that i will use 6th edition, raven’s 7th, Raven’s Plants, Biochemistry by Donald Voet, Molecular Biology of the Cell by Bruce Alberts</p>
<p>Mikepavlov reccomended these. Sound good to make it to the semis and even finals?</p>
<p>Does anyone have a decent estimate as to when the results will come out? (Sorry if this has been answered before >_<.)</p>
<p>3-5 results come out.</p>
<p>To make semis and finals Campbell is all you need. Don’t move on to anything else unless you have completely mastered every page of it, which takes a very long time.</p>
<p>Open Exam is free for discussion. All tests are in to CEE. </p>
<p>The results will come out later than 3/5, as per CEE (not their website).</p>
<p>waaait: the results aren’t coming out on march 5th? or was it " the results will come out no later than 3/5" ?</p>
<p>Huh, forgot 'bout this place. </p>
<p>I got a 37. I thought this was the easiest open I’d ever seen.</p>
<p>quote: The announcement will be later than March 5.</p>
<p>@cadaeibfed: if that’s not a ■■■■■, congrats! though i’m not sure how’d u’d know ur exact score already</p>
<p>Well said, darksigma!</p>
<p>Its safe to discuss answers/questions so lets start. The problems I remember was the lab question (table of info), the bird feeding the fish(it asked what type of behaviour it was) . Keep listing questions so we can compile a list to answer</p>
<ol>
<li>The answer was the only choice that started with arginine</li>
<li>Fixed action pattern</li>
</ol>
<p>@darksigma, i guessed the one with arginine first but that was cause i knew i wouldn’t know. mind to elaborate on why? if you are 100% certain.</p>
<p>Here is what I remember (take my answers with a grain of salt though):
- The first question about diffusion: CO2 > Glycerol > Sucrose > Chloride ion
- Western blot assay modification: I put the one about electricity but I think the answer is the one about denaturing the proteins.
- What is not produced by the anterior pituitary? ADH
- Lipid monolayer of archaea diagram: I believe it was choice A (look up the diagram on wikipedia)
- The ethology question about the army: Kin selection
- There was a question about habituation, but I forgot the answer choices. I’m pretty sure I got it right though.
- Turner syndrome: X0
- There was a question about radial cleavage. The answer was echinoderm (or something similar to that).
- Island biogeography (greatest equilibrium population) Answer: The island with the greatest distance from the mainland and with the largest size.
- The photomicrograph of the numerous cells: Red Blood Cells of frogs (look it up on google images–the other choices didn’t make much sense anyway e.g. the cells were definitely not sperm cells or human erythrocytes)
- Stomata open because… Answer: Active uptake of potassium ions
- There was a question asking about the concentration of pyrimidine; I believe the answer was 50%
- What is not an example of a secondary sex characteristic? Answer: Reproductive organs
- How does ADH work? Increases the expression of aquaporin channels
- Ascending loop of Henle is thicker because: Na-K-Cl cotransporter
- There was a question about what is not true regarding genetic drift? I think the answer was something along the lines that it stops variation or something.
- There was a recombination question, and I think the answer was 600:200:200:600
- What element should you first test for when there is a protein deficiency? I put sulfur. Another answer choice was iron.
- There was a question about sexual selection–I don’t remember it though.
- There was a question about the heart–I think the answer was right atrium.
- There was a question about the primary energy source of some sort of embryo, I think the answer was yolk sac but idk.
- There was a question about what amino acid would be least usable in allowing a gecko to climb up a wall (with diagrams of various amino acids as the answer choices). I put phenylalanine but I’m pretty sure that is wrong. I think we have to think in terms of Van der Waals forces or something.
- There was a question about vitamin deficiency. I guessed vitamin E–but I doubt that is correct.
- There was a question about pollen with answer choices like: dihaploid fertile, haploid sterile, etc.
- There was a question about how plants respond to light/darkness or something. The answer choices were Thigmonasty, Seismonasty, epinasty, nyctinasty. I put epinasty but I’m pretty sure the answer is nyctinasty.
- There was a question about Fick’s Law: Gills vs. Alveoli.
- There was a question about Multiple sclerosis treatment. The answer was closing potassium channels increase duration of action potential.
- There was a question about during what period did animals arise that resemble the body forms seen today. I put Cambrian because of the Cambrian explosion.</p>
<p>I’ll post more questions later. Have fun. Hope I was helpful.</p>
<p>Feedback to previous questions:
2. What were the other choices for the western blot: isoelectric point, denaturing the proteins. I think I picked the choice with the isoelectric point.
9. Wasn’t the island biogeography one: largest and closes to the main island?
13. What were some other choices for the secondary sexual characteristics question?
15. For the why the ascending loop is thicker, was there a choice saying its thicker because of more water channels/aquaporins? I’m asking this because I’m not sure if I picked the Na-K-Cl cotransporter.
19. I picked E, something about sexual selection poses risk to both male or female? Might have been wrong since they asked for what was false.
26. Was the answer to the Fick’s law: larger surface area or something in fish?</p>
<p>Additions to list:
29. In response to stress, fungus produces: zygosporangium?
30. Allopatric Speciation: less common than sympatric speciation or vice versa (since it may have asked for which is not true)
31. Allopatric Speciation: does not result from sexual selection
32. Jumping Bird: Was it A or C? There was a small difference in that A talked about showing off physical characteristics while C mentioned the word “courtship” and mentioned that the female could observe the male genes.
33. PTH
34. If liver was damaged, what would NOT happen: production of erythropoietin changed or something.
35. Klinefelter’s: something in Meiosis 2 of the mother.
36. Virus named Ijustmadethisup (don’t remember the question, unless it’s already mentioned?)</p>
<p>Feedback:
20. It was about injecting some sort of paralyzing/fixing chemical into which part of the heart.
21. Could this have been the question about which extraembryonic membranes are used for respiration? The answers were something like: (A) yolk sac (B) allantois (C) chorion (D) both A and B (E) both B and C. The answer was E.
22. gecko feet/Van der Waals forces: Van der Waals forces would make it a nonpolar amino acid.
26. I put that there was a larger gradient, thinking of countercurrent exchange in gills. Both gills and lungs have a large surface area.
32. There was one option that mentioned that the females responded to the good jumpers because that trait was correlated with good genes. It may have been A.</p>
<p>Addition:
37. Which order of birds would not feature strong flight muscles? I put Piciformes because they sounded small, but I think the answer was Galliformes (turkeys, chickens, quail, etc.) because they don’t fly very much.</p>
<p>@rhyme4life:</p>
<ol>
<li>I don’t remember the other choices. I put the isoelectric point, but protein denaturation seems more plausible. I’m not too familiar with molecular biology laboratory procedures though…</li>
<li>I put farther from the mainland, because being closer to the mainland would increase gene flow.</li>
<li>The descending loop is permeable to water, not the ascending loop. Ions (Na, K, Cl) are reabsorbed via the ascending loop. </li>
<li>Yeah, something like that. The other choices were something like: The fungi would begin to engage in mycorrhizae or something, which is wrong. The fungi was black bread mold (a zygomycete).
30-31. For some reason, I think that those were in the same question. It asked which was not true about allopatric speciation, and I thought one of the choices was allopatric speciation is less common than sympatric speciation, and another choice was allopatric speciation results sexual selection. Maybe it’s just me.</li>
<li>Yeah, I remember PTH. Was PTH a question or an answer?</li>
<li>Yes, that was the answer. I got it wrong though, since I forgot what Klinefelter’s syndrome was.</li>
</ol>
<p>@gbraing:
20. Yes, that was it. I forgot the name of the chemical though.
21. No, I am thinking of a different question. However, regarding extraembryonic membranes used for respiration, I agree that it was both allantois and chorion. Count that one as question 38.
22. Yes, indeed. Grr…</p>
<p>Addition:
39. There was a question like which of the following is not an advantage used to attract pollinators. The choices were sepals, petals, a foul odor, patterns visible only under UV light (or something). I put the UV floral patterns option, but I don’t think that’s right…</p>
<ol>
<li><p>There was a question about which of the following lacks a closed circulatory system. The answer was: Insecta.</p></li>
<li><p>There was a question with answer choices like: megaphylls, microphylls, etc. I don’t remember that question but I do remember getting angry at myself after the test for mixing up megaphyll and microphylls haha.</p></li>
<li><p>There was a question like which hormone is not paired with its function. I think I put thyroxin, but I don’t remember it that well.</p></li>
<li><p>There was another question about the term that describes cations going from soil to roots. I put cation cotransport, but the answer should have been cation exchange.</p></li>
</ol>
<p>As for the cutoff score, I’ll put my guess on 25. It was significantly harder than previous exams, but I don’t think it was as bad as the 2010 one (although it really depends on the person)…</p>
<p>The question about the bird classification was Struthioniformes. Those are flightless birds (kiwis, ostriches, cassowaries) and thus have no keel and no flight muscle anchorage. I am rather sure I got that one correct btw.</p>
<p>Sphenisciformes is the answer to that one, penguins,atually</p>
<p>question on the heart was left ventricle (whole animal fixing)</p>
<p>the lipid layer one was definitely not A. It was asking for MONOLAYER -> you need an amphiphilic molecule. A would’ve given a normal bilayer, thought it is found in archaea</p>
<p>@darksigma</p>
<p>Do you mind confirming the answers to the compiled list?</p>
