<p>savannnahs are grasslands which are very fertile btw.
and they are known for peroidic droughts, that hinder the growth of large trees.
therefore tropical rainforest had to be the answer</p>
<p>what was the question for the plants in the aquarium one? i cant even remember it </p>
<p>why did o2 increase when temp increased??</p>
<p>no the other aquarium question, not the one asking for the color of the light…</p>
<p>OHH i put enzyme function/optimum temp
but rainforests have poor nutrient soil? i dun think so – thats why i didnt choose it and chose savanna:/</p>
<p>closer to optimum temperature for the enzymes? i think that was the best answer</p>
<p>yeah idk about the nutrient soil but savannah makes no sense either way</p>
<p>im looking up savanna now lolll
“Low-nutrient soils” [Tropical</a>

i dunno that was a tricky q :(</p>
<p>PR says that many grasslands have “especially fertile soil.” It also describes tundra, saying “most plants are short.”</p>
<p>but are savannas and grass land the same?
i thought of the Lion king loll. and it seemed kinda dry around there</p>
<p>so what would a raw score of 60 be???</p>
<p>In fact the soils are very thin and the rock below them highly weathered - tropical rain forest</p>
<p>PR describes grasslands as “Grasslands (Savannas)” so I think they are definitely the same thing.</p>
<p>jw am i the only one who put savanna. it seems like im wrong 
anyways other answers we can confirm?</p>
<p>What did you guys get for the ion used in muscle contraction?</p>
<p>Also - yes. Bad soil was rainforest - straight outta barron’s
Tundra was the third one because it said high latitude also (which means nearer to the poles)</p>
<p>For the gene flow one, gene flow = loss or gain of genetic trait from a population. It’s better than drift.</p>
<p>oh snap for real? i put gene flow but then i after the test i thought it was genetic drift (since its about chance?)
i chose calcium btw for the muscle
yea now i think im wrong about the rainforest oh wells</p>
<p>“What did you guys get for the ion used in muscle contraction?”</p>
<p>I put calcium</p>
<p>it was calcium</p>
<p>What about the aquarium one? Where was the oxygen produced? Why did it increase?</p>
<p>and yes since it said chance, it was genetic drift because that is a change in the gene pool due to chance</p>
<p>Damn that’s -1.25…</p>
<p>How many can you miss and 800?</p>
