<p>cambium dividing, mesophyll chloroplasts</p>
<p>yes kwcty6888 10char…and diurnal 10char…it said most birds in the question and most birds are awake during day</p>
<p>^ yay! Thats what I had, too.
(kwcty6888)</p>
<p>cambium cells give rise to secondary (width) growth. palisade mesophyll has the most chloroplasts, gas exchange was guard cell</p>
<p>For the pigment question, I was actually debating between green and red. Green is a plausible answer for obvious reasonw - chlorophyll reflects green light and thus would not allow for photosynthesis, but I went ahead and picked red only because it’s on the other side of the visible light spectrum.</p>
<p>The molecule was a lipid because it had two hydrocarbon tails and a phosphate head, the characteristics of a phospholipid to be exact.</p>
<p>Just out of curiosity, did anyone else do E? It seems like most people did M.</p>
<p>hesterprynne, i agree with you!! this test was administered in october 2009 and the general consensus then was the it was the higher temp is closer to the enzyme optimum temp!!</p>
<p>what did you guys have for the substrates
C02 H2O one</p>
<p>I did E</p>
<p>Which biome had low nutrient soil and broad leaved trees? Rainforest? I actually pu savannah cause the low nutrient threw me off T.T</p>
<p>Tundra for close to ground plants?</p>
<p>10char^ gregbob</p>
<p>facedownclap, i put E as well</p>
<p>@facedownclap: I put CO2 and H2O (it’s E rite?)
Anyone confirms the color light question?? I’m so confused :-s</p>
<p>And the last group of question (Bio M) is confusing too. Which gene can be used to analyze the relationship between Human 1 and 2? And which one is the least different between the experimented organisms? :-s</p>
<p>@gregbob: yay!! But someone above said photolysis does not require enzymes (which seems to be right, I am having my book with me and it says nothing about enzymes) I just did not remember if the answer has the word “photolysis” in it…</p>
<p>Put E also…
I said rainforest for low nutrient soil and savannah for close to ground plants O.o</p>
<p>low nutrient soil was tundra…wasnt sure about the close to ground one but i put savanna</p>
<p>Ya I’m pretty sure it was enzyme optimal temp
And yes, rainforest is broad leaves nd poor soil nutrition</p>
<p>tundra because it said high latitude or high altitude i think</p>
<p>low to ground plants was tundra, it said high lattitudes i think. low nutrient soil was rainforests… the last question i put whichever one was the most different between the two organisms</p>
<p>I dont know about you guys but that test was extremely easy/joke. For the first 60 questions all you needed was a first year biology class and some anatomy background and you were set. The ap biology played mostly in the molecular section.</p>
<p>wouldn’t call it a joke. wasn’t that bad, but definitely not a joke</p>
<p>torture i thought… but guess not…</p>
