<p>Okay guys.. for anyone who is reviewing why dont we post a question and then the next person will answer and post their own question.</p>
<p>Or if one is so inclined they can talk about what they've been studying: terms, systems, concepts,etc.</p>
<p>Love canal is an example of what?</p>
<p>^
“Early in the 1940s, a chemical company purchased the abandoned Love Canal to use as a dump, filled it to cpacity with toxic waste, and covered the toxins with dirt. The company then sold the land to the area’s Board of Education. The site was then used as an elementary school and playground. Heavy rains in 1977 caused toxins to seep into the soil, making people in the neighborhood suffer serious illnesses such as Epilepsy, live malfunctions, miscarriages, skin sores, rectal bleeding, and birth defects. The reulting public outcry encouraged Congress to pass CERCLA (Superfund) in 1980.” </p>

<p>What is El Nino and La Nina?</p>
<p>^ El Nino is when the warm water in the Pacific Ocean moves eastward. La Nina- the intervening years when the warm water remains in the Western Pacific.
They are significant because they caused excess rain and droughts. (Crazy weather lol)</p>
<p>What is Ozone? How is it made?</p>
<p>Ozone (O3) is a secondary pollutant that is in photochemical smog. Pollutants such as photochemical oxides are hit by sunlight, and react forming the O3. Ozone in the troposhere causes many problems, such as eye irritation, wheezing, and lung damage. Troposheric Ozone is not to be confused with stratospheric ozone, which is very helpful for the environment (absorbs UV rays) </p>
<p>Hmmmm… Please give a general description of the Nitrogen cycle and its major components</p>
<p>Nitrogen fixation: free nitrogen is transformed into ammonia or ammonium- usually done by Rhizobum (spelling?) in legumes
Nitrification: ammonia and ammonium are turned into nitrates and nitrites
Assimilation: plants turn NOx into proteins and DNA that they can use
Ammonification: NOx released from plants when they die is turned into ammonia/ ammonium
Denitrification: ammonia/ammonium is transofrmed back into free nitrogen</p>
<p>Name and descibe the stages of the demographic transition model.</p>
<p>^
stage 1 - high birth and death rates (preindustrial)
stage 2 - falling death rate but high birth rate
stage 3 - sharper decline in birth and death rate
stage 4 - low birth and death rate or ZPG</p>
<p>list cultivation methods to reduce soil degredation.</p>
<p>Does anybody know where I can find practice tests/questions?</p>
<p>^ </p>
<p>Plant trees, don’t expose soil to air, use organic fertilizers, leave crop residue behind, crop rotation, etc…</p>
<p>what kind of reaction occurs in fuel cells</p>
<p>in the FRQs when it says state TWO of this or THREE of that, is it true they will only look at the first TWO or THREE answers?</p>
<p>obviously?..
they’re required to, pretty sure</p>
<p>
</p>
<p>The packet specifically stated that extra examples would not be considered. It also specifically said do not write the answers to the FRQs in outline form, because outline form would not be accepted. The other kids didn’t bother to read the back of the pink booklet, and I saw them writing in outline form. I feel sorry for them, since I know they had better answers than me but I don’t think they’ll get any points for it.</p>
<p>For questions just asking you calculate something, we just need to show the calculations and the answer+units, right? We don’t need to put it in a complete sentence…right? Cuz I didn’t. =/</p>
<p>^ I think showing your work and the answer along with units is all you need.</p>
<p>I also saw that they said not to write in outline form. Does that mean the answer to the entire question had to be in paragraph form or was it okay to label each section as follows</p>
<ol>
<li>
(a) info for answer written in paragraph form
(b) info for answer written in paragraph form
(c) (i)info for answer written in paragraph form
(ii)info for answer written in paragraph form</li>
</ol>
<p>Because if it all had to be in paragraph form…I’m screwed.</p>
<p>I think they mean you can’t just do bullet points and listing facts. I’m sure you can break it up into different sections as long as they’re in complete sentences.</p>
<p>Does anybody know the scoring breakdown?</p>
<p>@alicimoo: thanks so much. I almost had a minor heart attack there for a minute.</p>
<p>@1a1: I’ve heard that it is exactly the same as the bio breakdown. Essays are a little harder to judge though becuase each essay may be worth the same number of points but each one is weighted differently (at least that is how my teacher explained it).</p>
<p>Yea just for clarification you CAN break the essays up into parts: part A, part B, etc. </p>
<p>I ended up skipping a lot of lines in between those separate parts though, so I don’t know how that will turn out.</p>
<p>So we can’t talk about FRQ yet, right?</p>
<p>I really want to know if I got that one math problem right.</p>
