<p>I did Lead, I said it is released in many countries through leaded gasoline. I said you can breathe it in and it can also enter the body through puncture wounds. Two ways to reduce it were restrict leaded gasoline and stop driving as much. Would this work???</p>
<p>^I thank that would suffice, I also used lead, but I talked about how lead is used in many household paints.</p>
<p>Can you inhale mercury particles?</p>
<p>I did lead too, but I said it had to do w/ paint…
But was my statement right?</p>
<p>Yeahh, I did lead too. I talked about paints and gasoline but then I also said that lead enters the atmosphere through smelting and then enter the soil and plants. andd a way to reduce that is to use metals that give off less pollution (/better quality metals).</p>
<p>I used batteries as my example for lead? is this right/specific enough? And i said that its a neurotoxin and harms the developmental growth of children and causes them to have lower intelligences. does this work?</p>
<p>^^ Yeah, the part about the children that should work. I said that too. I have no idea about batteries.</p>
<p>I said Lead can build up in the body and later cause cancer. Is that good enough?</p>
<p>I talked about lead in outdated water pipes, would that work?</p>
<p>So it was the first year that APES was at my school for a long time and everyone thought that our teacher was a disorganized mess, but I would just like to say that she prepared us so well for the test. Everyone thought this was so dumb before, but in the middle of the year, one of her assignments was assigning each student in the class with a different invasive species to research and present to the class the next week. On presentation day, we all presented each of ours and she also made us fill out a chart with all of the invasive species presented that day. She also made us do a chart for examples of pesticides, biodiversity hotspots, and also endangered animals which everyone thought was just too much.</p>
<p>And so it finally came to AP Exam day and I got to the Free-Response question and I proudly wrote about the Kudzu Vine and how it invaded the southern US and blocked the sunlight from native plants. I was so glad she made us do this because in class everyone just underestimated my teacher so much because she had only taught Aquatic Science on-level before and everyone thought that she would not be ready to teach an AP class, but honestly it was the exact opposite. I felt most prepared for the APES test than any other test I took this year (Maybe because it was probably the easiest), but I really thought that my teacher helped a whole bunch.</p>
<p>Also the Toad you guys were talking about earlier is the Cane Toad in Australia being introduced to wipe out the native Cane beetles… I actually wrote about this in the invasive species being introduced to wipe out a nonnative species, but the Cane beetles were actually native species so I probably missed that part.</p>
<p>Did anyone else think that the question (for the 1st free response, I think?) about how you had to give two examples of something that would result in rising sea levels also caused climate change? I don’t remember… but I got stuck there for a bit because of the weird wording and I think I ended up writing something about glaciers melting and ocean thermohaline circulation disruption because I couldn’t really think of anything else that causes rising sea levels.</p>
<p>can mercury be assimilated by plants?</p>
<p>I also wrote that sea levels would rise due to ice caps and glaciers melting and then I remembered after the test that a rise in global temperature would change the pattern of rainfall and cause violent storms through ESNO. What a loss.</p>
<p>Can mercury be inhaled and cause damage to the lungs?</p>
<p>hey guys,</p>
<p>im wondering…how many pts do you think that question about using a nonnative species to control an invasive species is worth? 2-3 pts is my guess becuz that question had a lot of parts and the total number of pts for each question is 10</p>
<p>Hopefully not very many because I kind of Bsed my way through that question.</p>
<p>Can breathing mercury cause respiratory problems? When I think of mercury, I think of neurological problems, but for some odd reason I put that it causes respiratory problems :(</p>
<p>If you phrased it correctly, you will get credit. Respiratory problems can be caused by exposure to high concentrations of mercury vapor. However, exposure only to low but frequently available concentrations of mercury vapor is generally associated with neurological issues.</p>

<p>Thank you, ksarmand! I feel slightly better about my response :)</p>
<p>Is ap environmental science an easy class to take it online? please advise me.</p>
<p>

<p>Having prepared for the exam in a formal class setting, I truly cannot say whether or not it is “easy.” However, if you diligently prepare by close reading of whatever textbook you have, regular assessments through the tests provided by your online course, and outside assignments, I cannot see why you would not do well. </p>

Through the course of the year, I ended up reading it from cover to cover. My teacher also had a subscription to Nature magazine, which I read periodically. Most importantly of all, I read the course description provided by the College Board. This was a godsend, as one of the questions on the exam was taken directly from that description, and it dealt with something I had neither read in my textbook nor discussed in class.</p>
