<p>cuz if it was straight DNA strands lined up against each other… it’d HAVE to look like this:</p>

<p>but i guess it was winding. although how did it show winding if the 2 DNA strands were all … straight and flat?</p>

302

<p>They twisted it like this… The 1s represent one stand. 2s represent another stand. Again. not 100% how many twists there was. </p>

Forgive the crude drawing but that’s what it looked like somewhat</p>

304

<p>No one remembers the answer choices specifically for B or C right?</p>

305

<p>I’m leaning more towards C but all I know is that the answer choice below the one I’m talking about had mismatched nucleotides</p>

306

<p>jesus i am now thoroughly confused by how twisted dna can look straight and straight dna could actually be twisted. i…kind of get it?</p>

307

<p>does anyone know the wording of the question? that’d help</p>

308

<p>I put Phosphorus doesn’t cycle through the atmosphere.</p>

309

<p>I took this test at 8:30 in NJ, and it’s been almost 12 hours, so I really don’t remember ;_; I’d love to see the question again, though!</p>

310

<p>i’d love to see the test again… along with my answer sheet.</p>

311

<p>^agreeed…ahhh am i the only one that did bad here? sigh I feel like poop</p>

312

<p>Oh wait. okay i get it now… the diagrams for dna i think looked like this
5 3
|||||
|||||
3 5
(won’t let me do the spacing correctly)
or whatever, rather than
5—3
3—5</p>

<p>That confused me…</p>

313

<p>@houston Nah. I omitted8 and got +5 wrong. I usually score 730-740 on the practice. I did horrible. Don’t even feel like doing my weekend homework. So disapointed.</p>

314

<p>One of my friends told me that the one that was false for the Phosphorus question was that the ocean does not erode it or something like that. </p>

<p>And ApManiac, Phosphorus does not travel in the atmosphere, but i think the choice was, Phosphorus DOES NOT plays a large role in the atmosphere. Not sure…</p>

315

<p>i think the phosphorus question asked which one was NOT true. so the atmosphere one would be right. which means it’d be the wrong answer.</p>

316

<p>we get the results in 3 weeks</p>

317

<p>oh… i felt so stupid and ashamed after that test… do you guys konw when the scores come out?</p>

318

<p>in three weeks i’ll probably check the cb website, get super nervous, and die of a heart attack before the page ever loads to show me my score</p>

319

<p>I think this one was harder than previous years, so maybe a 4 question curve?</p>

320

<p>4? i guess i could settle for that. as much as possible… but 4 sounds reasonable</p>
