<p>Average percents don’t work anyways.</p>
<p>You can’t average 100 and 50 because it’s apples and oranges, that is it say the quantifiable number in either case is undefined.</p>
<p>It’s just bad math practice.</p>
<p>For the last question on the M section, I was wondering about the Ampicillin and resistant bacteria graph. </p>
<p>Was it ampicillin caused a mutation that was visible near day 4? or there were already resistant bacteria?</p>
<p>yeah, i wasn’t sure either. i said there was already resistant bacteria.
did u get day 2 has fastest rate of decrease of the bacteria?</p>
<p>i believe it is 75% since they do not tell you if father is homozygous or heterozygous. Therefore, there is a 50% chance that he is homozygous. 50% chance that he is heterozygous. If he is homozygous, then son will definitely have it. if he is heterozygous, son has 50% chance of having it.</p>
<p>100%<em>.5 +50%</em>.5 gives you 75%</p>
<p>im pretty sure that this is right unless homozygous dominant condition is fatal. please correct me if im wrong. thanks</p>
<p>after the ap test last yr i remember this test was EASY</p>
<p>got a 790. most pple in my class got 800’s. (very small class)</p>
<p>don’t worry about it!</p>
<p>Yeah I said that that some of the bacteria were resistant to the streptomycin. I feel like that would explain why the amount of bacteria decreased and then increased.</p>
<p>diiamondss-Wasn’t it 4 days? Wouldn’t you observe the decrease in bacteria after it already happens? Because at Day 2, I don’t think that the graph would have indicated a huge drop in the amount of bacteria.</p>
<p>but you could assume he is heterozygous for if he was homozogyous then all the offspring would get hnuntigntons and that was not a possibility</p>
<p>About the biome one:</p>
<p>I picked Tundra -_- I feel really stupid xDDDDD I thought that Tundra = farmland</p>
<p>Look, I came across the identical question in a practice test somewhere. And I was confused, but the answer was 50%. In this situation you would probably assume that he wouldn’t be dominant homozygous.</p>
<p>Can anyone who took the M section recall the equations and questions/answers for the radioactive O18 section?</p>
<p>Google “tropical rain forest food production” and “grasslands food production” and grasslands comes up with better results for food production lol. So i guess that one was grasslands. (I put tropical rainforest =/)</p>
<p>can someone PLEASE help me with the question involving the plant lab with gravitropism and photropism and thigmotropism or something…i dont remember it at ALL and i’m starting to freak out. Was that on molecular or ecology or the main test?</p>
<p>^^^ All I remember is that it was just asking where the marked O went from one side to another… so you just followed it</p>
<p>^ it was on the main test I think… the first pic was grav, the second was thigmo, the third was photo(but the question didn’t ask for that third one)</p>
<p>Protagonizer:
- the oxygen in 12 H2O is what makes up the oxygen in 6 O2 product.
- the oxygen in the 6 CO2 is what makes up the oxygen in the C6H12O6 (glucose) and the 6 H2O
- 6 carbons (from the 6 CO2) make up one molecule of C6H12O6
- I think I put it didn’t matter if the oxygen was labeled or not (not sure about this though)</p>
<p>Did that answer all your questions or were there more? (I can’t recall)</p>
<p>For the one asking about which of the following do angiosperms do but not most vertebrates, what was the answer? I put ‘carb storage’ b/c asexual reproduction wouldnt make sense since most angiosperms dont even reproduce asexually.</p>
<p>what would a -6 with no omits be?</p>
<p>@tristan </p>
<p>angiosperms DO reproduce asexually. self fertilization where their own pollen attaches to their own stigma counts as asexual reproduction. and they both have carbohydrate storage. angiosperms store carbs as starch and vertebrates store it as glycogen.</p>
<p>The conversion charts from Sparknotes and PR seem to indicate that 2-3 wrong is 800, and everything on from that is ten points off with no curve. Do you guys really think it’ll be that harsh? I haven’t talked to anyone who thought it was easy…I’m hoping it was harder than usual. Of course, I know someone will say it was easy…</p>
<p>hey, a couple of questions that haven’t been discussed too much yet</p>
<p>for the bacteria plate set, did anyone get “at 4 days, resistance in bacteria became evident”</p>
<p>the crustaceans q was the one with external fertilization and chitinous exosk; does anyone remember the other answer choices</p>
<p>does anyone remember the questions the photoperiod…phototaxis answers each corresponded to</p>
<p>and on #3 for the PTH questions, one of the answers was along the lines of "body will find another way to regulate calcium; does anyone remember the other answers</p>
<p>what score would 5-6 wrong, no omitted give?</p>
<p>thanks!</p>
<p>Yes
Chitinous exoskeleton
photoperiod for spring and summer, i guess phototaxis for birds</p>
<p>Gives you a 770-780 I believe.</p>
<p>I thought that would be more toward 790ish.
How much would the choice of E or M add/decrease on average?</p>
<p>Correct
VVVVV</p>
