<p>^Exactly. It’s a /</p>
<p>A downward line makes no sense, when a tree falls down, you dont have a lot of ants around it
And it said from the time it falls to the time it has decomposed entirely</p>
<p>yeah like kili16 said it was a bell curve, because when the tree falls down initially, there are a lot more nutrients. that leads to a huge spike; once the tree completley decomposes/gets eaten, the bugs begin to die</p>
<p>also, what is the byproduct of a peptide bond? plus, where would the bond take place? near the H=O or the nitrogen option?</p>
<p>I put this for the peptide bond:</p>
<p>Byproduct = H2O because it’s a dehydration process.
The bond would be placed between the amino group and carboxyl group of two amino acids (would take both H’s from the amino group of one, and one oxygen from the carboxyl group of the other) but I’m not sure if that’s right. I learned this in like November.</p>
<p>What will about 5 wrong and 3 omits be?</p>
<p>I don’t think the test was that bad…
Some answers for confirmation:
Leech is the one not in the phylum Arthropoda
Photoreceptors are in the retina.
Blood type O? I think? For least likely genotype b/n AB and type A
Spleen gets rid of red blood cells after they stop functioning.</p>
<p>For E, the arithmetic difference b/n energy produced by producers and energy used up by producers + consumers would be net COMMUNITY production, right? It would be net primary productivity if it didn’t involve consumers.</p>
<p>Was the guy’s hypothesis about vines wrong? Because the ones in the experimental group grew slower than those in the control?</p>
<p>I believe Leeches are nematodes or something, so yeah.
Photoreceptors are in the retina (I got this one wrong)
I did the Punnett squares, O is least likely.</p>
<p>Not sure about the Spleen, saw that question and did M! lol</p>
<p>Astroblue, I put that the hypothesis was wrong, because it seemed (based on the results) that the vines DID need the trees to grow to their full potential.</p>
<p>hey how does 3-4 wrong and no omit look like? im hoping for a 790 or maybe an 800</p>
<p>Leeches are annelids, from the group Hyrudinea
The peptide bond was between the C and the N
Spleen is red blood filtration
And the hypothesis was wrong</p>
<p>I think some people are misunderstanding. </p>
<p>Your score from 200-800 IS NOT curved. There is a consistent formula used to calculate each score for each test during every national testing day. What is curved is your percentile. </p>
<p>For instance, let’s say you score a 630 on this, supposedly, much more difficult test. On any other test, you would be in the 50 percentile. On this test, however, you may be in the 62 percentile. But, both scores are 630 because you got about the same number of questions correct, incorrect, and/or omitted.</p>
<p>The subject tests ARE NOT like the AP exams, in which scores from 1-5 are determined by a bell curve of students’ performance on each exam.</p>
<p>Hope I helped to clarify :)</p>
<p>Yup, you’re right Kili.</p>
<p>What about the one w/ proteins and carbs? Dehydration synthesis, right?</p>
<p>Are you guys sure Estrogen is all 3? I remember distinctly that progesterone and lutenizing hormone were the two hormones that contribute mostly to secondary sex characteristics in females</p>
<p>And are you sure myraven about that? How come in past years you could miss 4-5 for an 800, spark notes says you can miss 1, Kaplan says you can miss 2. If there was a magical consistent formula, why don’t the guide books says the same thing?</p>
<p>@Aquawater98 It’s dehydration in both</p>
<p>@kiki2025 even if estrogen contributes to some extent, then is true. Besides remember LH does nothing on its own, it just tell the oocyte to produce estrogen. So there you go :)</p>
<p>“In humans, the estrogens are formed in the ovary, adrenal cortex, testis, and fetoplacental unit, and are responsible for female secondary sex characteristic development, and, during the menstrual cycle, act on the female genitalia to produce an environment suitable for fertilization, implantation, and nutrition of the early embryo.”</p>
<p>I’m pretty sure it’s all three.</p>
<p>Kiki, I don’t think it asked whether or not it contributed MOST to secondary sex characteristics. I believe it just said whether or not it did. And, it does.</p>
<p>Yeah, estrogen promotes secondary characteristics.</p>
<p>[Estrogen</a> - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Estrogen]Estrogen”>Estrogen - Wikipedia) go down to function.</p>
<p>I’m so annoyed at myself, I put the bell curve for the insects but started MAJORLY second-guessing and ended up leaving it blank. ):</p>
<p>also, I’m not sure for the answers on the chromosome attachment question… I put A. ):</p>
<p>I’m feeling pretty good about this test. And for the eye is the iris the muscle that controls the amount of light that gets let in? I know the pupil is the one that changes but i wasn’t sure if it was controlled by the iris or not. And also cornea wasn’t there for the following question, which was where the light went through and got focused…so which one was that?</p>
<p>Kili16, what do you mean peptide bond between C and N? If you took M, it didn’t ask for that. It asked for the bond involved in binding ANOTHER amino acid, which was the one within the carboxyl (COOH) group.</p>
