November 2010 - Biology (E/M)

<p>exactly!!! i found so much that i had no idea what they were!!</p>

<p>most people think it was hard or easy?</p>

<p>It was pretty damn easy, minus maximum 5 questions in which I guessed. The rest was pure. I intended to do E but did M, LORD did E look hard!</p>

<p>All in all, I left none blank, unlike my Korean :(</p>

<p>tell me penicillin comes from bacteria :(</p>

<p>EDIT</p>

<p>^^</p>

<p>they do</p>

<p>What got me was the vertebrates with no bony bones? I guessed between sharks and frogs, chose sharks?</p>

<p>I chose frogs…i was between those two also</p>

<p>i was confused between picking hair and bristle. I ended up picking bristle T.T i assume i got it wrong T.T</p>

<p>EDIT : i put sharks also for that one because they have skeletons made out of cartilage instead of bone no sure though</p>

<p>IT COMES FROM FUNGUS. pennicilin. </p>

<p>just google pennicilin discovery.</p>

<p>Yeah, I think it was hair…</p>

<p>What were the questions for the light spectrum again?</p>

<p>OH! And also, the heart of the fish diagram, wt f was the most analagous to the dog’s lungs? I chose 5 that pointed to the lungs? Was it a dirt easy question or a dumb question used to trick us?</p>

<p>@ nytra</p>

<p>you are correct. Penicillin grows from fungus as a secondary metabolite. I chose fungus. I chose bacteria for something though. Don’t remember</p>

<p>[How</a> was Penicillin Discovered and Developed?](<a href=“How Was Penicillin Discovered and Developed? (with pictures)”>How Was Penicillin Discovered and Developed? (with pictures))</p>

<p>It says bacteria.</p>

<p>if you read the above cited article, it directly says, “Surprisingly, he saw not only the mold growing on the staphylococci bacteria, but a clear zone around the mold. The Penicillium mold, the precursor to penicillin, was dissolving the deadly staphylococci bacteria.”</p>

<p>Penicillin affects the peptidoglycan walls of bacteria. It’s not from it.</p>

<p>lol i read the first line. but wasnt the question, how was it discovered or what led to the discovery of penicillin? you’re probably right though.</p>

<p>and was it a fish heart? the heart diagram thing? </p>

<p>… and I think it was a shark, not a frog, cause sharks have “soft” cartilage skeletons, not bony ones. if you google frog skeleton, you will see that frogs actually have a full system of legit bones.</p>

<p>yes i put fish heart too.</p>

<p>IDK? What heart was it? I said fish … I think?</p>

<p>i think i did really well considering the circumstances… i just went to barnes and nobles yesterday and read as much of the PR book before the store closed… not ideal preparation obviously. i kinda relied on stuff i remembered from freshman year bio.</p>

<p>@boramk:
i wasnt sure if it was a fish… it didn’t show any gills supplying oxygen to the blood or whatever.</p>

<p>@ nritya</p>

<p>same. I used the stuff I learnt from school (I do A Levels), but there was much more in the SAT, just much less detail, so it was easy for me to power through the Barron’s book yesterday. Took me all day though</p>
