June SAT Biology E/M Pre/Post Test

<p>I just guessed that it wouldn’t increase species variety because I considered phosphate to be another nutrient and applied it to what I knew about eutrophication. - so I guess I got lucky there</p>

<p>for anyone who took ecology–the question about what an example of directional selection, which answer choice did you choose if you remember what you chose?</p>

<p>It was the larger beaks. [Directional</a> selection - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Directional_selection]Directional”>Directional selection - Wikipedia)</p>

<p>^ I second that.</p>

<p>What were the answers to the set of questions on pathogens and people of different ages?</p>

<p>Okay for the one with the caterpillars going all pupa earlier, was it an example of “interdepence [insert word]”</p>

<p>I COMPLETELY GUESSED. well not completely, i didnt like the other answers</p>

<p>interdependence organism. </p>

<p>Then another option was niche partitioning
another was competition exclusion.
forgot the other 2</p>

<p>what’ was the correct answer?</p>

<p>For the M section, what was the one with the oxygen 18 isotope (what did experiment one prove?) I said that the water was incorporated into something (lol I forget). Think it was A</p>

<p>But according to the webster’s dictionary, chemosynthesis is limited to bacteria and fungi, which means that some fungi MUST be able to do chemosynthesis.
[Dictionary</a> - Definition of chemosynthesis](<a href=“http://www.websters-online-dictionary.org/definitions/chemosynthesis?cx=partner-pub-0939450753529744%3Av0qd01-tdlq&cof=FORID%3A9&ie=UTF-8&q=chemosynthesis&sa=Search#922]Dictionary”>http://www.websters-online-dictionary.org/definitions/chemosynthesis?cx=partner-pub-0939450753529744%3Av0qd01-tdlq&cof=FORID%3A9&ie=UTF-8&q=chemosynthesis&sa=Search#922)</p>

<p>and if you google chemosynthetic fungi you should be able to find several results…</p>

<p>[Competitive</a> exclusion principle - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Competitive_exclusion_principle]Competitive”>Competitive exclusion principle - Wikipedia)</p>

<p>Niche partitioning – [Niche</a> differentiation - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Niche_differentiation]Niche”>Ecological niche - Wikipedia)</p>

<p>interdependence? dunno if this is what it means though. its the only thing i can find.

</p>

<p>wait ericr333
for the adaptive radiation, was that on numbers 1-60?</p>

<p>zhuzhupet: </p>

<p>So what did you say that fungi are not?</p>

<p>I said that fungi could be decomposers, autotrophs, and parasites.</p>

<p>Oh, was it one of those I, II, III, II or III questions?
Because I thought it was what are fungi not.</p>

<p>I said fungi were only parasites and decomposers. I thought they were all heterotrophs?</p>

<p>yes AP, it was a I II III question …I dislike those…</p>

<p>^Princeton review claimed they were all heterotrophs. Anyway what was the one on the M test about the photosynthesis equation with oxygen isotope and it asked you to make a conclusion</p>

<p>AGH THAT TEST WAS HARDDDD…
well all we have to do now is wait…</p>

<p>and @AP, about the diseases affecting different age groups, I said that the first disease most affected children under 5. either that or kids below 5 were affected longer. something like that.</p>

<p>Yeah, it was a I II III question.</p>
