<p>Here’s something that may help for that hemoglobin question </p>

<p>[Mathews/van</a> Holde/Ahern 3rd Edition](<a href=“Welcome to The Chemistry Place”>Welcome to The Chemistry Place)</p>

<p>For the corn syrup question I think I put somewhere along the lines that if the scientists gave them the corn syrup, then the fetuses wouldn’t have dissolved or something like that. The corn syrup line on the graph was a straight line which means they didn’t give the rats the nutrition for fetus development or something.
And for the last question for that experiment, I think I put something like anything above a certain number of the DET (I forget the name) is dangerous.</p>

<p>For the thymine question, the answer I put didn’t say they would have the same percentage of adenine/thymine as guanine/cytosine. I think it was saying that because the two brothers had the same thymine/adenine (lets say 64% and 64%), they would also have the same percentage of guanine/cytosine (32% and 32%).</p>

<p>what were those questions about “10) there is no effect on rats less than 10 days old” or “7)The two fishes are most closely related (forgot the names)”??</p>

<p>also was the phosphorous cycle one ocean sediments or detergent? can somebody explain it</p>

<p>also, i put the same percentage for the adenine/thymine question, did the same thing as blissalay</p>

<p>I really don’t remember the corn syrup question or the guanine/cytosine question. was this on the M section of the test or the general 60 questions?</p>

<p>what does everyone think about the curve? i personally thought the test was difficult</p>

<p>Those were in the general section… Probably. </p>

<p>And damn, I don’t know about the Adenine and guanine question. Wasn’t the question worded differently? Oh godd</p>

<p>The fish question:
It showed us a little
Phylogenetic tree and told
Us to find the most closely related. </p>

<p>And, apparently, google says that it was the detergents :/</p>

<p>Yeah, this test was pretty hard. I hope the curve is good. The college board official book states that you can have 8 mistakes and still get a 750…</p>

<p>YESSS, thank you Google <3 </p>

<p>Pretty sure that corn syrup question was on molecular. </p>

<p>Idk, this is my second time taking bio, and I felt the same this time as I did last time. And I made a 700 last time. :confused: But I did molecular last time, and I heard the curve is more generous for ecology. Fingers crossed the curve is big this time.</p>

<p>For the nail in the tree why can’t it be the one that says that trees embed around anything in it and just grow around it. The answer choice that just explained how trees grow doesn’t explain why the nail was at the same height level.</p>

<p>Also what was the answer to the question that asked for what white blood cells DONT do? I put that it makes hemoglobin.</p>

<p>Yes, it doesn’t make hemoglobin.</p>

<p>And for the tree one, wasn’t the only logical answer the one about how the tree grows?</p>

<p>all i remember about the nail and tree question was that I got (A).</p>

<p>Same here^ tree grows from the top of the something…</p>

<p>So I guess it was the one. It talked about how the tree grew from the shoot or something</p>

<p>Were there any other questions that people found difficult?</p>

<p>We discussed almost all the questions in the general section… If you can remember more, just post it.</p>

<p>What’s the answer for the fish question?</p>

<p>What about the hemoglobin one with the lamprey fish?</p>

<p>The nail was at the same height level because shoots develop and grow at their tips. This growth is accomplished with the help of an apical meristem cell division. The shoot apical meristem is located at the extreme tip of the shoot.</p>
