<p>Is it OK to discuss now?</p>
<p>ya im pretty sure its been 48 hrs…</p>
<p>We can talk about it now!</p>
<p>ok then…
question 1a: why was the councilwoman right in saying that there are other effects of nitrogen fertilizers?
I said because of algal blooms and cultural eutrophication in Lake Fremont
question 1b: why was councilman Bob wrong in his statement?
I bsed this because I had no clue what they were referring to…
and i dont remember the rest of that…
except for e or d, which was explain part of the nitrogen cycle</p>
<p>Here’s a link to the FRQs for reference:</p>
<p><a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;
<p>Here’s my answers (Tell me if I got them right/wrong):</p>
<p>1a: eutrophication
1b: I think I said NO2 but it was a bunch of BS
1c: O3; combination of O2 + O; respiratory illness
1d: BS ammonification nitrification</p>
<p>2a: BS
2b: BS
2c: 547,000???; $80,000 (totally wrong); BS
2d: 750-800 just guessed</p>
<p>3a: energy; BS flood control
3b: siltation buildup; fish harm
3c: BS
3d: BS
3e: BS</p>
<p>4a: can’t remember
4b: better resistance against pests
4c: better crop output
4d: drip irrigation to prevent salinization and some other BS
4e: BSBSBS</p>
<p>1b) Identify a nitrogen-containing primary pollutant that contributes to the formation of photochemical smog. Describe how that primary pollutant forms and explain why Councilman Budd was wrong.
^^^ how was councilman Budd wrong? I was so confused over that… I just made up some BS that just taking away nitrous oxides would not completely get rid of photochemical smog, because there are many components to it (ozone, SO2, VOCs, etc.)</p>
<p>and for 2, i got about 500,000 kwh and $80,000 too…</p>
<p>I think it had something to do with Council Budd thinking that the nitrogen-fertilizers were the only source of possible nitrogen that could contribute to photochemical smog.
I wrote about how there are other sources that nitrogen could come from, certain smokestack wastes i think?</p>
<p>yeah thats probably it…
would mentioning an explosion of dinoflagellates (the red tide) for 3-d (effects of climate change on Colorado river hydrology) be off topic? i thought that if temperature went up, bacteria and other microogranisms might flourish in the lake collected behind the dam, and cause health problems… does that have nothing to do with hydrology???
(and if it doesn’t, hopefully ill get points for spelling dinoflagellates right :P)</p>
<p>For the cow question, it’s 731 cows. I screwed up my math and put 733 cows. :(</p>
<p>Did anybody get 16 years and 25,000 dollars in savings?</p>
<p>^ Lol I was running out of time so I didn’t work the cow question out, I just estimated around 800, then after looking at it again I wrote in parenthesis (closer to 750). They probably won’t count that lol.</p>
<p>now i realized why i did that so quickly; i thought that the rounding rule from cii still applied… ^#@$! i guess 800 cows would be a little high heh</p>
<p>Did anybody get 16 years and 25,000 dollars in savings?</p>
<p>sorry 1a1 i just skipped over that one when i took and still can’t figure it out… anyone know when collegeboard puts out the scoring guidelines for these? after july?</p>
<p>im not sure if this will happen but i think its ok if you put 733 cows, when looking at how past AP exams are graded on math sections there is usually a range of numbers that they will accept around the right answer- so like they might take 730-735, or something like that.</p>
<p>Councilman Budd was wrong because the nitrogen from fertilizers doesn’t isn’t direct air pollution, the NOx from combustion is. Nitrogen in fertilizers is nitrate so it won’t cause smog.</p>
<p>^ I think I got 733 cows, too! Sweet, I actually got something on APES. :D</p>
<p>I had such a breakdown with my elementary multiplication/division skills… (which I have no excuse for since I’m helping kids out with it every week at my job at Kumon!). So I just guesstimated 800 cows for that one question, then returned to it at the end and narrowed it into approx. 730, so I’m ecstatic if I was only off by 3! w00t</p>
<p>1a) eutrophication
b) NO2, cars and factories are other sources
c) O3, lung irritant, (dont remember what i put for the other one), reaction with sunlight
d) nitrification and ammonification of ammoina to nitrates to protein and dna</p>
<p>2a) methane, collect, burn, steam, spin turbine
b) i 547500 kwh
ii $55,000
iii 7 years
c) less runoff of waste into water source, less eutrophication , and less inflitration of waste into groundwater
d) 731 (i set everything up right…but just divided wrong…i got 721…you think i will get credit?)</p>
<p>3a) energy and flooding control down river
b) build up of sediment and obstacle for salmon reproduction
c) dont remember
d) faster water flow from melting snow, hotter temperature, and more runoff because of desertification (?)
e) coastal areas have loss of biodiversity and some areas many experience coral bleaching from increased UV light</p>
<p>4a)i 100 percent
ii 10 hectacres/year
iii 80 hectacres
iv too expensive to keep producing
b) agriculture crops to lands that are not suitable before and something else…
c) genetic resistance(?..dont remember what i put) and expensive
d) agroforestry and intercropping
e) less pollution from less transportation, less money or cost for seller and buyer because of less need to transport</p>
<p>can anyone give me a prediction on what i got in eahc FRQ? THANKS!!!</p>
