<p>@SCC2014 definitely 800</p>
<p>lol a good chunk of barrons wasn’t even on the test</p>
<p>im so glad that the plants section wasn’t on it</p>
<p>@SCC: Yes, that is in 800 range.</p>
<p>^how would the tree question be a bell curve?</p>
<p>Really nothing in the human body on the test</p>
<p>@coolkid555 I explained it a while ago but basically ants come, then the food is less and less so they go away until you have 0 ants in the end</p>
<p>^^if they had put an ear diagram instead of an eye i would have missed all of the questions lol</p>
<p>@kili16 ohhh, ok thanks!! lol</p>
<p>For the tree question, I put a linear line going downward. As it decomposes more, less animals will stay remain for food. I can see how it would make a bell curve, but I think the question assumed that there were insects in the area.</p>
<p>@redsn0w but that would mean there was a bunch of ants before</p>
<p>think of putting a piece of food on the sidewalk…after a while some ants come…and after that loads of ants come</p>
<p>Hopefully the curve is more generous.</p>
<p>I chose the steadily downward line. My logic was that there were insects living in the tree, and as it decomposes, there’s less space for them to live. I am probably wrong.</p>
<p>This thread makes me feel a lot more confident that I am going to get over a 700 (which has been my goal). Maybe if I’m lucky I’ll hit 750! I got a lot of the same answers as you did, almost all of them I believe.</p>
<p>The tree one, as I said, was very vague so I went for the basic explanation. Those types of questions are cr*p because you spend a lot of time thinking when they were probably thinking a about a really stupid situation. But we will see once the scores come up :)</p>
<p>@SCC2014 I think this test was harder than most, the eye thing probably killed a couple of people. Plus those experiments are sometimes confusing so lets hope for a nice curve</p>
<p>im fairly certain coral reef is a biome</p>
<p>so minus three pretty close to the 800 range as well?</p>
<p>Just saying, I don’t remember that question ever mentioning biome. I’m pretty sure it said region, or something like that. </p>
<p>Besides, I’m pretty sure coral reef would fall under “marine biome”, which Barron’s went over pretty extensively.</p>
<p>Coral reef was the answer without a doubt because the other 4 are not very diverse biomes</p>
<p>Coral Reef is definitely the answer.</p>
<p>For the tree one, it was definitely a linear line going downwards.
Cuz the questions specified that graph starts when tree is already fallen.</p>
<p>… This thread is making me even more nervous about the number of questions I got wrong but more hopeful about the curve …</p>
<p>Once the tree falls, insects are permitted to feed on it, which precipitates a spike in their population. Once the tree fully decomposes, the insects no longer have a food source and die. It’s that simple.</p>
