<p>one question was strangely worded
the corn/pH lab asked which elements were controlled
the CONTROLS = temperature and light
but the pH was CONTROLLED in terms of controlling how acidic/basic it was</p>
<p>so was the answer temp light AND pH
or just temp and light</p>
<p>Yeah I was running out of time at that point so I skimmed those little paragraphs. Not too confident about this test but oh well.</p>
<p>@biobaby- tht is exactly how I FELT! I think i ended up going with the 2 and not ph-but idk now…
also yea for the phylo tree it must have been diet b/c im sure all the other things are used</p>
<p>@biobaby, I put all three but I was not sure. It was a complete guess to me.</p>
<p>i said the controls were temp and light, the only way to change the acidity was to change the pH so that was the independant variable</p>
<p>i put all 3 because i thought they were trying to trick me!</p>
<p>got the lymph question wrong
i guessed it was produced at the lymph nodes
but lymph is from interstitial fluid from between cells</p>
<p>Completely agree, I was like “what do they mean?” I ended up with all three since that seemed like it would be the simplest answer. I was trying not to over think it.</p>
<p>meh. 2 wrong for sure (I missed the tree one and I feel really dumb for that), and 2 skipped. Probably missed closer to 5 though.</p>
<p>yea actually im feeling pretty bad about this as well… anyone else rem difficult M questions?</p>
<p>@runallday4
i said nucleotide as well and for the other question i said what they eat b/c the others were all things that people use to see how organisms are related</p>
<p>after 24 hours is the dialysis bag isotonic?</p>
<p>and was the conclusion for the dialysis lab that sugar was smaller than starch?</p>
<p>can someone go over the nerve/muscle diagram questions</p>
<p>That controlled question made me really angry- that was a TERRIBLE question. I don’t even remember whether I said all three or not.</p>
<p>The nerve/ muscle diagram took a minute for me to understand, but basically just follow the pathway that the nerve would take from the input site (the skin segment) to figure out the answers. It sort of reminded me of a maze from a child’s newspaper.</p>
<p>Yes, isotonic. I don’t really remember the other question on that one, sorry.</p>
<p>for the muscle/nerve stuff-was it literally playing connect the dots-or did i just screw that up?! lol</p>
<p>for the dialysis bag, i thought it wasn’t isotonic after 24 hours- anyone else get the same?</p>
<p>OH- does anyone rem the one in the beginning: which of these is involved in gametogenesis or something like that? i thought there were 2 ans choices-testes and ovaries…
idk!
Also, can someone explain y the bag would be isotonic, if there was still tons of solutes in the bags that didnt diffuse across??</p>
<p>It was isotonic I believe. The tons of solutes that didn’t diffuse across are not able to pass the selectively permeable membrane. Because of this, osmosis occurs like it said in the problem. Also, with the movement of sugar and water, it ultimately becomes isotonic.</p>
<p>what do you guys think the curve will this time?</p>
<p>I guess I see now that the answer was the food one. That’s one wrong. Anyone have a definite answer for the island with the lowest extinction rate?</p>
