May-2012- Biology (E/M)

<p>since RNA polymerase was the only protein there i put that! ASFLGKJ WHO IS WITH ME</p>

<p>the answer to that one was insulin, not RNA polymerase cause it talked about proteins secreted by the pancreas.</p>

<p>lol i just realized that perhaps people could look up ans and so i deleted lol</p>

<p>RNA polymerase wasnt the answer
I believe it was Insulin because the radioactive amino acids were added to the secretory cells that would make insulin in the pancreas
the amino acids were found on the rough er as ribosomes made them and then the golgi as they were packaged and then they are secreted</p>

<p>What was the one where there was a ribose, a phosphate, and a nitrogenous base? I wasn’t sure if it was nucleotide or RNA, but I said nucleotide, since it was very specific that there was only one of each.</p>

<p>Also, which of the processes wouldn’t be good for making a phylogeny tree?
Options were teeth structure, what they eat, amino acids, DNA, and something else. I said amino acids. Anyone else?</p>

<p>for the tree scar questions, was the tree young or old or WHAT!?</p>

<p>did anyone understand the nerves, muscles, skin of an earthworm diagram??</p>

<p>okay disregard what i said haha-i guess everyone might be done by now. So speaking of that question-wat was the purpose of that experiment-would it be for the path of protein travel or something?</p>

<p>Growth happens at the apical meristem so the scar doesn’t move at all. The answer was .9. That’s been on a lot of previous tests.</p>

<p>the answer was a nucleotide to the adenine and phosphate and ribose.</p>

<p>the tree scar would be the same height?
since tree grows at the top and the bottom stays the same</p>

<p>The one with the phylogenetic tree, I put what they eat, not amino acids because cytochrome c is used to investigate evolutionary relationships between species.</p>

<p>@kashmoney, for that I put to see where insulin goes to after being secreted by the pancreas or something like that. I wasn’t sure.</p>

<p>-the protein one was insulin
-hydra and jellyfish</p>

<p>it was not amino acid sequence? but diff codons can still code for the same amino acid sequence. Horses have a more similar amino acid sequence to humans in comparison to apes. however their phylogeny isnt as strong.</p>

<p>can someone explain the muscle, nerve diagram with the questions?</p>

<p>The phylogeny tree was the Dietary nourishment (or whatever the wording was).</p>

<p>Yeah I considered that because it was a question in the princeton review book. But animal digest a lot of the same things, so I dont know how that can possibly be used to determine phylogeny.</p>

<p>3 wrong and 1 skip is bad right? ■■ this imma cancel</p>

<p>@ShutUpUPlay2Muc. see i was about to say that-but i went with path of something to be secreted based on the little paragraph of why this thing was done-but idk</p>
