<p>thingschange, pretty sure there were 5 for the chart. </p>
<p>Piano, I thought the mRNA and protein one was combined. B/c I remember debating internally during the test and also on this thread a couple days ago about whether it was the ribosome or tRNA. tRNA definitely doesn’t have any rRNA.
Yup, I took level 2. Well… I don’t know where you live, but I went to this program called Elite Educational Institute. The teachers are really good. I haven’t taken calc yet either, I just finished pre-calc. I asked my friend who got an 800, and she said that you really don’t need calc to do the test, but it is easier once you know derivatives and stuff.</p>
<p>@thingschange There was another about ribosomes being in both prokaryotic and eukaryotic cells. Maybe that’s it? I think that was the general section.</p>
<p>General:
Questions 1 and 2: mitochondria
Question 3: chloroplast
Question 4: cell membrane
5-7. Eye questions in order: retina, iris, lens
8. Neuronal signaling to muscle: chemical signals
9. Rat lab:-80% -same diet
10. Abnormal chromosome seperation: <_>
11. Fossils evolutionary order: seastar, shark, dinosaur, bird, whale
12. most closely related to primates: whale
13. Convergent evolution: shark and whale
14. Uric acid: bird and dinosaur
15. Global Warming question: accumulation of greenhouse gases
16-17. Population growth: human-exponential, insects still in debate between bell curve and negative slope
18. Estrogen question: all 3
19. Not part of arthropods: leeches
20. Lichens: mutualism
21. Tundra: cannot grow roots into soil
22. Most Diverse biome: coral reef
23. Clumped population: due to mating
24. Implantation of embryo: lining of uterus
25. Cats and Dogs: same phylum
26-28. Vine lab: - does not confirm hypothesis - vines are dependent on trees for support AND nutrients - graph that starts w/ experimental faster than control but soon turns into control much faster than experimental (very steep graph)
29-31. Plant diagram: paliside cells, guard cells (stomata), vascular bundle (one that looked like veins)
32. Bicarbonate: acts as buffer
33. least possible offspring: O blood type
34. negative feedback as an answer
35. Both protein and RNA: ribosome
36. Mule: hybrid
37. White chickens mating: purebred offspring
38. Deer that reached carrying capacity: logistic graph (choice B)
39. Rat lab: prolonged waiting decreases chances of offspring survival
40-42. Transcripton / translation pics: hydrogen bond was number 2, connecting the two bases in DNA - ribosome was big circular thing (number 5) - ribosome contained both mRNA and protein
43. Origin of life came from mixing amino acids in ancient, Earth-like atmosphere
44. Darwin’s theory of evolution based on populations (not organisms, cells, etc.)

<p>E:
sends blood throughout body = aorta
pumps blood to lungs = right ventricle
Diff b/n energy produced by producers and energy taken up by producers + consumers = net community production
most net primary production (it asked what had the most energy after accounting for respiration) = alfalfa field (the biome in the first column)
Alfalfa field’s net primary production = 9200
Two areas w/ no net community production = the ones w/ 0 on the bottom row, or the two columns that were on the right. (Tropical rain forest and chapparal or something?)
Difference between one row and another row (net primary prod - heterotroph respiration?) EITHER THIS OR some question that also had net community resp as the answer
When specialization of tissue occurs during development = gastrulation
spleen does what? = filters out ethryocytes in blood
Jointed appendages - what has 3 pairs of legs? = insects
Mice in an environment w/ very dark or very white areas = disruptive selection
Birds’ beaks = stabilizing
Cheetah w/ little variability underwent bottleneck effect long ago
14-15. yeast: asexual reproduction - yeast accumulating would lead to lack of O2 as they used it up for resp

<p>M:
starch stores energy in plants
changing blood type or whatever would not affect hemoglobin shape
Restriction enzymes work by something about complementary DNA
companion cells
Glycogen is a short-term energy storage molecule
Dehydration reactions
H2O is another product of making a polymer
8-10. Amino acid diagram: polymer made of amino acids - bond number 5 (at the right of the diagram) forms the peptide bond - the hydrogen atoms at the end would be removed
the order question was letter E…I dont remember the roman numerals
using a molecule that is more effective in highlighting DNA was the one where DNA was bolded and the spindle was a dashed line
i believe there was another question in the mitosis lab where the answer was anaphase
<p>AAAAAAAAAAHHHH this is confusing… I think the prokaryote and eukaryote was the one you were referring to.
there were THREE questions for that diagram. I dont remember putting ribosome twice. Im going crazy.</p>
<p>You guys so for that transcription diagram, 1 was the phosphate backbone of DNA, 2 was the hydrogen bonds b/n DNA bases, 3 was ?, 4 was mRNA, 5 was ribosome, 6 was tRNA, 7 was growing polypeptide.</p>
<p>For M, there was a picture of a polymer that you had to identify. I don’t think you guys took M, but #7 that you have already goes with. Basically, there were 3 questions for a diagram of two amino acids linked together.
The first was that it was an polymer made of amino acids.
The second was that the bond number 5 (at the right of the diagram) forms the peptide bond.
The third was that H2O is the byproduct of forming a polymer (you already have that).
So that’s two more for the M section…</p>
<p>Although it wasn’t a question, I don’t know what 3 was. It was definitely at the top half of the digram. I have a feeling it was circular (maybe ???), so what would that be? It wasn’t a ribosome.</p>
<p>Yeah my friend drew it out, and it was circular. It wasn’t the nuclear membrane b/c it was attached to the DNA, not surrounding it. Plus transcription and translation were going on at the same time, signaling that this is a prokaryotic cell.</p>
<p>Yeah, I’m actually pretty sure it would be RNA polymerase because it was at the top of the diagram, meaning it represented transcription. RNA polymerase is portrayed as a circular object in my biology book. And RNA polymerase also plays an integral role in transcription. So…that’s what I think it was…</p>
<p>Also, RNA polymerase functions in prokaryotic transcription too. I’m not too knowledgeable about this though Lol so maybe you shouldn’t trust me…</p>
<p>Ok another one for the M portion was about the wavelengths. They had a photosynthetic plant in the green wavelength and they said what would happen to it. The right answer was that oxygen-seekeng bacteria would not come near it (because there would be no photosynthetic in the green part of the spectrum).</p>
<p>Also, wasn’t there one about RNA processing? I think in the general section. I might be thinking of a practice test, though. Can anyone confirm this?</p>
<p>@SAT200 Yeah, that right. The last one (that we need to compile, not the actual last question) is about ATP changing the shape of myosin. The answer also mentioned ATP becoming ADP or something.
Also, I think there was a question in the general section about a chemical signal being released at a neuromuscular junction.</p>

Done!</p>
<p>There were some questions on crosses with a table in the general section. Anyone remember them?
I think one asked about the trait. Pretty sure it was autosomal recessive.
Then another asked about the genotype of one of the animals (the female in cross 3 I think?).</p>
<p>rat lab all mother rats need to have what in common? (experimental constant) = diet</p>
<p>A separate genetics problem was autosomal recessive.
There was one with a table of three crosses. Purple or green leaves of corn. I posted this somewhere on this thread already.</p>
Lol so maybe you shouldn’t trust me…</p>
