<p>wow
i missed the rainforest one too ><</p>
<p>what did u guys get for the fertilizer one</p>
<p>Desperate, as far as I know (before the test):</p>
<p>PTH takes calcium out of the bones and into the body (for nerves/muscles etc to use).</p>
<p>Calcitonin (not mentioned) takes it out of the blood and puts it back into the bones.</p>
<p>Idk if that helps. I don’t remember the questions exactly. The questions on that lab were confusing, but otherwise straightforward.</p>
<p>@Xombie, really? I’m pretty sure it’s grassland. Rain forest makes no sense. While it may seem like a logical answer at first given the diversity of life there, that doesn’t mean it produces the most human food.</p>
<p>Humans don’t really eat any of the animals that live in rain forests, and neither do they eat the trees that live there.</p>
<p>We eat grains, rice, and livestock. Most of these, I think, grow and live on grasslands.</p>

<p>I kind of hope it’s grasslands just because I had Rain forest at first and switched to deciduous for whatever reason. So if it’s grasslands, at least I would have been wrong either way, lol. I have 8 wrong so far for M, so that’s a raw score of 70. What score would that approximately by?</p>
<p>One of the question is what happens to calcium blood levels if you take PTH out.
Another was what happens if a person has only 50mg of calcium due to low calcium diet???</p>
<p>Well it could have been grassland.</p>
<p>A few pages back people were saying it was rainforest, however.</p>
<p>[Rainforest</a> Maker - Rainforest and Food](<a href=“RainForest Maker :: About RainforestMaker :: Grow Back the Earth’s Rainforests”>RainForest Maker :: About RainforestMaker :: Grow Back the Earth’s Rainforests)</p>
<p>“At least 80% of the developed world’s food originated in the tropical rainforest. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.”</p>
<p>I don’t know how legit that site is though, and how the grasslands compare.</p>
<p>Keyword: ORIGINATED.</p>
<p>That means these fruits EVOLVED in the rainforest, but it doesn’t mean that we grow most of them there today.</p>
<p>Plus… what I’ve realized is that it seems as if the beginning of every discussion thread is filled with clueless guys who don’t know what they’re talking about. And then they slowly start to funnel out. So don’t worry about what other people were saying. :P</p>
<p>However, if I’m wrong, and the answer was grasslands, I’d be very happy. :)</p>
<p>Pinkstar: Decrease and then I put body reacts to increase levels
Rainforest provides most of the world’s foods. I think it was in my APES book.
I guessed on the fertilizer one and put inorganic compounds. But that makes sense b/c fertilizers do contain that for plants.</p>
<p>Well we’ll see in July. :D</p>
<p>^June, right? I thought scores come out June 25. Unless there’s QAS for this testing.</p>
<p>For the one about the twin brothers, was the next answer 5 and 6 or 1 and 5?</p>
<p>TtRr was tall pink? and A was the answer to the first quetsion on E? Convergence for the question about the finches?</p>
<p>So is the plant fertilizer one inorganic compounds? doesnt fertilizer contain phosporus, magnesium, etc. stuff like that?</p>
<p>Yes convergence for the bird question.</p>
<p>Fertilizer is inorganic. The question after twin brothers was 5 and 6.</p>
<p>You guys should try reading the thread first.</p>
<p>i am hoping the right answer is rain forest because in my barrons book it syas the rain forst account for 20 % of the worlds food production but I was pretty mad that the marine biome wasnt one of the answer choice</p>
<p>ok so what would be omit one and get like 4-6 wrong</p>
<p>Whee.
Tay-sachs was NOT lysosomes. Incorrect assumption after skimming the question and having basic knowledge about the disease. The question was something along the lines of due to deffective genes, there is a buildup. This could give us a few possibilities-protein enzymes or ribosomes, as both are coded for by genes (mRNA/rRNA). However, something wrong with the enzyme wouldn’t be an issue with a lysosome itself, whose only real function is as vesicular sac that carries approximately 40 hydrolytic enzymes. So, the answer seems to be the ribosome. If there is a deffective gene for the rRNA that makes up the two ribosomal subunits, it won’t be able to properly translate the mRNA into proteins, leading to the build up.</p>
<p>For Huntingtons, every single resource I am seeing is saying online that HH doesn’t kill at the embryonic stage as many here seem to be suggesting. “Most patients are heterozygous for the mutant copy of huntingtin however in some rare cases there are individuals who are homozygous for the disease-causing allele.
Homozygosity for the disease gene does NOT cause death at the embryo stage as the previous answer stated.” Also, despite the rarity of HH individuals, this is an isolated case. We have absolutely no knowledge about the father’s environment, his parents, etc. So, without any of this knowledge, it is EQUALLY likely that he is HH or Hh. So, 75%.</p>
<p>My opinion and reasoning behind PTH. Please comment and verify:</p>
<p>PTH’s function in the body is to increase calcium. The graph was misleading because it was about negative feedback and showed calcium on x-axis. That meant that when calcium was high, PTH would be low so that more calcium isn’t released. It also made sense when calcium was at zero because PTH was at 600, meaning that the body released a lot of PTH to restore normal calcium levels. </p>
<p>I put decrease for PTH and removing parathyroid. Decrease for Calcium and removing parathyroid, but might also be fluctuate. Third one was body doing stuff to increase calcium.</p>
<p>
</p>
<p>You’re thinking too hard. All genetic disorders involve RNA/protein synthesis, obviously. Tay-Sachs stems from a mutation of a hydrolytic enzyme in the lysosomes. Trust me, I did a presentation involving it.</p>
<p>But that’s not a deficiency with the lysosome itself.</p>
