<p>just know those three and i think it’ll be enuf for the real test.</p>
<p>I noticed that the review books don’t go into much detail with Molecular Genetics like with specific enzymes and their functions. Is that just not emphasized on the test, or should I review it again?</p>
<p>Alright, I guess I’ll start up the questions again.</p>
<p>Which plant hormone plays a main role in phototropisms?</p>
<p>It should be auxins. Auxins occupies the shaded side of the stem and enhance cell elongation so that’s why stem bends toward light.</p>
<p>what is the process of cell shrinking when placed into something like NaCl ?</p>
<p>Plasmolysis</p>
<p>Retroviruses go through which process?</p>
<p>plasmolysis?</p>
<p>Correct. I just did the mini-diagnostic test on Barron’s. I feel so stupid circling that answer then crossed out. I did the same one for the right next question. There are 2 more I knew the answer but circled the wrong one. I feel so stupid right now.</p>
<p>It should be reverse transcription which is done by an enzyme called reverse transcriptase. </p>
<p>After 2 years of exposure to an anti-bacteria chemical, the bacteria becomes resistant to that chemical. What type of evolution is this ?</p>
<p>^^don’t feel bad, i can’t get passed a 670 on sparknotes and you don’t even want to know my score on the diagnostic… as for that question i have no idea except maybe mutation?</p>
<p>^^ yeah, i second that.
guess i’ll start up another question:
in humans, the rate of breathing is controlled by which:
a. lungs
b. cerebrum
c. medulla oblongata
d. cerebellum
e. pleura</p>
<p>It’s A. I know that b,c,and d are parts of the brain, but what is e?</p>
<p>Synthesized glucose will most likely be stored as…?</p>
<p>^^ the back of the book says c, medulla oblongata.</p>
<p>I think directional selection can be a better answer. Do you guys think so ? Probably my wording was not good enough.</p>
<p>@hartown: The bad thing about the diagnostic test is that you have to do both E and M part to know your score. If not, your score will not be accurate.</p>
<p>It should be medulla since that part of the brain control a lot of involuntary activities.</p>
<p>@pink33837: should it be glycogen in animals and starch in plants ?</p>
<p>what does the hormone Adrenaline do ?</p>
<p>Medulla controls rate of breathing not lungs. </p>
<p>Adrenaline initiates flight-or-fight- increased heart rate…</p>
<p>Synthesized glucose is stored as glycogen…??</p>
<p>Oh, heehee.</p>
<p>but isnt directional selectionwhne one phenotype replaces the otheri n the gene pool like the peppered moth?</p>
<p>what are ecolgical factors like wind, water, pH, and temperature</p>
<p>Directional selection is a shift towards one phenotype b/c that phenotype makes the organism more fit so yeah. It’s not really replacing, just a higher frequency of it. </p>
<p>I don’t get your question. Like density-independent factors?</p>
<p>ok i mean either biotic or abiotic</p>
<p>abiotic 10 char</p>
<p>Ok, I guess I’ll ask another question.</p>
<p>What is it called when two organisms have developed similar morphological features due to similar environmental niches? (ex. bat wing & bumblebee wing)
A) Divergent Evolution
B) Adaptive Radiation
C) Convergent Evolution
D) Genetic Drift
E) Madness</p>
<p>convergent evolution</p>
