Biology SAT II POST-EXAM discussion!

Test Preparation

<p>THE GRAPH WITH THE PIE CHART WAS THE ANSWER…i hope</p>

122

<p>although A did not have a control, i assumed that the control just started at 0 while the other 3 bars just show how much above the control they increased… the pie graph had no logical sense in it when you actually thought about it</p>

123

<p>but you cant do it without the control because then you have nothing to compare the data to and it would be pretty much useless info</p>

124

<p>For people who also took the AP bio exam this may:
I was suprised, this didn’t seem much easier than the AP multiple choice really. In fact, I felt like the questions were less clearly written for some reason…any opinions?</p>

125

<p>all the SAT’s are always unclearly written…lol</p>

126

<p>Well, this was my first SAT II…I never got this feeling with SAT I questions. I mean…the question difficulty was probably lower than the AP, but the fact that the questions were less clear made it harder, if that makes any sense.</p>

127

<p>I would just love that which graph was wrong question to be the pie chart!</p>

<p>Does anybody recall if the first chart, the one without the control as a trial, maybe had a y axis labeled Improvement or something like that. Know what I mean? Then you wouldnt need the control because it’s saying how much better it was than the control. The pie, though? What a pointless graph. Comments?</p>

128

<p>Since graph A’s title ( i dont remember exactly what it was) but it said something like Increased Growth-therefore we don’t need the control because the growth of the control is already taken out of the graph</p>

129

<p>i think it was the first graph, cuz like sea shell said, without a control the graph is useless. the pie chart one shows the proportions or percentages of change.</p>

130

<p>VietAnn, thanks for somewhat confidently confirming that… wheee!</p>

<p>And fruita, the pie chart gives not proportions of change, but useless proportions between the different trials, which don’t matter and are a silly way to interpret the data.</p>

131

<p>who knows…screw these SAT subject tests…i was sick the entire time. i was about to get up and leave :(</p>

132

<p>fruita, I know what you mean. I hope I did well, I made some really stupid/careless mistakes by rushing.</p>

133

<p>easier than May’s?</p>

134

<p>Another thing. For the farmer/bull question, the consensus here is that the farmer was cheated. However, choice D was that the guarantee was unreasonable because it’s impossible to be sure from selective breeding that the animal doesn’t have the allele. I think this is the more plausible answer. Agree, or disagree?</p>

135

<p>Awww…I put E. I think I screwed up the test, even though I’m Asian :(</p>

<p>I wasn’t ready for this test, but when I looked at it, the E looked easy and I thought M section was going to be hard, but then again…M was easier! To my horror I took E. Anyone else thought this test was hard?</p>

136

<p>no, bc the farmer was clearly cheated. If the bull had no recessive alleles, then it would have been impossible for the offspring to display recessive traits. As for the graph, im with the pie chart. choice A didnt have the control…but like someone said before, the titled was INCREASE in growth, meaning that the values plotted on the graph are just additions to the control thats already assumed. Teh pie graph, however, doesnt make sense because the amount of growth do not add up to 100 percent.</p>

137

<p>question about 30,000 genes </p>

<p>B) 30,000 proteins
C) 30,000 copies of one gene</p>

138

<p>So I was right about the farmer?</p>

<p>The 30,000 human genome, what was that about? According to Dictionary.com- this is a genome</p>

<ol>
<li>The total genetic content contained in a haploid set of chromosomes in eukaryotes, in a single chromosome in bacteria, or in the DNA or RNA of viruses.</li>
<li>An organism’s genetic material.</li>
</ol>

139

<ol>
<li>can we have a clear answer with the interval… i put 20 b/c the population doubles in 40 hours. for some reason, i reasoned that it’s 20 b/c of that fact… lol </li>
</ol>

<p>2) 36which is list effective in growth of the 3 3 3 3 plots of plants - phosphorus
No!- that’s nitrogen because it’s least effective … the 2nd column was smaller then the 3rd column which was phosphorus. Whatever the nurient is (phos or nitro), i put the nurient under the 2nd column.</p>

<ol>
<li>what was the recombination question and answer?</li>
</ol>

140

<p>its 30,000 different types of proteins. a gene codes for a protein. so 30,000 differnet genes can code for 30,000 differnet proteins.</p>
