June 2009 - Biology

<p>^The answer to that was C I remember.</p>

<p>^ so we can talk about specifics?</p>

<p>for the mendalian question i thought it was the agriculture one because he used agriculture… right?
maybe i got that one wrong…</p>

<p>tapeworms
(rapid?) reproduction (by eggs? - not sure if this was part of it), toxins, and NO digestive system
which is true? I put II only. I don’t remember seeing I and II</p>

<p>Do alligators or crocs secrete urea or uric acid?</p>

<p>uric acid…I think.</p>

<p>Also since PTH acts in response to blood calcium levels…the question which asks as PTH hormone decreases that would have to mean that the blood calcium was increasing. So I have to disagree with you Keaseby Nights.</p>

<p>Im pretty sure its uric acid</p>

<p>is the mendel one really QA?</p>

<p>btw, which biome had the greatest food production?
its supposed to be marine, but it wasn’t there, so I just put grasslands (although i didnt know whether they were referring to a savanna type one or more temperate)</p>

<p>for reptiles - uric acid in the desert.</p>

<p>I said grasslands. It was the best answer choice there.</p>

<p>Uric acid is solid and reduces water loss. I also said grasslands for that question.</p>

<p>I put rainforest - greatest diversity of life in general…?</p>

<p>lizards secreted uric acid correct?
and in the molecular section, what would happen when the TAT mRNA inhibitor was added? i put no growth in either but was also thought that it could be possible for protein growth to continue from preexisting mRNA</p>

<p>crocs/alligators do excrete uric acid because it was something about arid areas and in arid areas they wouldnt want to let off any water, they need it…water - urine and uric acid - no water. (i think)</p>

<p>Yes no increase in either. Was that like choice D?</p>

<p>i put tropical rainforest for the biome question…?</p>

<p>ichiruki - yeah, rainforest provide 20% food.</p>

<p>what should be the answer for the Mendel’s question ?? Should it be A ??</p>

<p>meadow: yeah i think it was D; thanks.</p>

<p>for the mendel question i put something about pea plants…only one choice included pea plants and thats what i put but i think its wrong</p>

<p>there was one question like what do an adult insect and a crustacean have in common? what was that answer?</p>

<p>“Also since PTH acts in response to blood calcium levels…the question which asks as PTH hormone decreases that would have to mean that the blood calcium was increasing. So I have to disagree with you Keaseby Nights.”</p>

<p>I know I put the correct answer for the PTH questions; I’m merely stating the logic behind my interpretation of the graph.</p>

<p>what was the Cellular respiration and fermentation question</p>
