<p>I thought the test was harder than past exams.</p>
<p>THe test was certain harder than the past ones.
Here's a bunch of questions (M test). I need to see
whether i need to cancel or not.</p>
<p>Position of Grasshopper’s (1)legs (2)excretion organ (3)reproductive organ. I chose “A” for all three questions…(the most back part).</p>
<p>Diseases: polio- bacteria; eliminated but kept in government labs- smallpox; devastating disease that kill a lot every year- malaria; protistan disease- malaria. There’s one more question in this matching section, I forgot.</p>
<p>Orchid self-pollinates and one species of bird: coevolution something..</p>
<p>There were two sets of flower pollinating questions: one set in the last: black is dominant over brown. And another set: the color was incomplete dominant or something?</p>
<p>Hardy weignburg: random mating</p>
<p>There was one short question about which doesn’t have exoskeleton, and a list of organisms…I forgot does anyone remember?</p>
<p>And there was one question which I believed the answer was LH…</p>
<p>And another question, regarding estrogen (or LH, forgot which one), I believe the answer for that was “ovary”?</p>
<p>First question of M section (#81), ‘What can’t we find out about this molecule’s formula C6H12O6’? I chose the ‘kind of atoms’..because we can’t figure out if its isotopes or..yea..</p>
<p>There was one question..I forgot but the answer, I believe, was ‘Sequence of amino acids’ Wait, wat was the question?</p>
<p>Sickle-cell amenia, like the disease is something that one amino acid is miscoded in a codon, what is the effect: codes for abnormal protein??</p>
<p>There was one set of question (with a graph) about hormone (one graph about its radioactivity in uterus, etc, and one graph about its radioactivity inside a cell) I said ‘it binds to a receptor in cytoplasm and transported to nucleus..’ and for the following question I said it’s estrogen, since the hormone’s radioactivity was high in uterus..I think estrogen was the only choice that is related to reproduction??</p>
<p>The question about when homologous pairs separate. I chose “anaphase I”.</p>
<p>The question about (this was HARD), that plasmid was detached from microtubules during metaphase, and pulled back to the opposite side..and reattached to spindle fiber and repositioned in the middle of the cell..: I chose “cytokinesis never occurs until they’re fully separated at the end of poles”..hope I’m right.</p>
<p>A set of questions about fetal/maternal hemoglobins. One question I said “fetal hemoglobin is more saturated (or has more affinity??) than the maternal hemoglobin”. Am I right?? </p>
<p>One question with a picture, about secreting an enzyme that breaksdown DNA into nucleotides…(or protein into a.a.), “where does the enzyme come from?” I chose “pancreas”..i think the question had something to do with small intestine…</p>
<p>I think there was a separate question about what happens to DNA after you consume DNA, I said breaks down into nucleotides. (I’m sure)</p>
<p>There was a question…hmm like bacteria and human..what happens when bacteria gets into human’s body..I forgot about this question, does anyone remember??</p>
<p>One set of questions about Purifying Steps (with a table chart). I said for one question that “enzymes should be cooled to prevent protein denaturation..” others seems wrong. I was looking for answers like ‘consistent environment/temp’, but other choices were like “vary temp, etc”. </p>
<p>One set of questions about, with dishes of E.Coli bacteria. I said the control dish was “2”. I was confused between 1 and 2, but there’s one sentence that says they also used dish 1 and 5 during the experiment, so I chose “2” as the control of the experiment. Does anyone remember more questions in this set???</p>
<p>During photosynthesis, O2 comes from water.</p>
<p>Which of the following doesn’t happen in mitochondria? I chose “glycolysis (cytoplasm).”</p>
<p>Does anyone remember about the black guinea pig, test cross question?</p>
<p>Moths use pheromone to find matings…</p>
<p>Salamander is the amphibian..</p>
<p>A question regarding amniotic egg, I guess it asked for its advantage? I chose the answer like “gets nutrients from ‘yolk sac”. I was confused between that answer and “doesn’t dry up in terrestrial.” What’s your answer? I think I got wrong..</p>
<p>What is the advantage of asexual reproduction? I said “E: mutation can’t pass on from parent to..F1 generation” thing. I don’t think adaptive characteristics pass on because adaptive characteristic is a change in somatic cell, not sex cell, and change in somatic cell doesn’t affect its off spring. What do u think?</p>
<p>One question how humans can walk, stuff? I chose “humans are bilateral.” </p>
<p>How are kingdoms organized? I said, “How old they are and their celluar structures.”</p>
<p>The blood type question: Father has O type, marries with a woman. What is not a possible bloodtype of their offsprings: I chose AB.</p>
<p>The bee or fly that doesn’t have enzyme that oxidize alcohol. I chose that “fly/bee has better resistant to alcohol”, but I think I’m wrong.</p>
<p>One set of questions with two graphs, like red-legged bird and black-legged bird living in spaces. There was one question what happens when it’s intermediate, rather than high or low. I just chose “red legged lives in wide and the other lives in narrow,” just following the original wide/narrow graph. I ignored the height graph. Others seemed wrong.</p>
<p>One question about “which of the following is not a characteristic of chordate”? choices were like dorsal nerve cord, gills, etc. I forgot my answer. Do u remember?
Which of the following is not a characteristic of individual, not population? I chose “phenotype of an individual”.</p>
<p>Which is used for movement? Choices were ciliates, flagellum, and microvillie. I chose only “ciliates and flagellum.”</p>
<p>polio is definitely a virus</p>
<p>Virus was one of the choices??</p>
<p>no, so i don't think polio was the right answer. I put malaria, but I don't think that's right either. does this mean the curve will be better?</p>
<p>i'm sure that Protist cause malaria. THen what disease does bacteria cause..damn. I'm expecting a killer curve.</p>
<p>ohh, that question asked about which one would antibiotics work on. Do they work on protists?</p>
<p>The one eradicated for sure is smallpox (as polio still exists).</p>
<p>The greatest killer I believe is polio.</p>
<p>The one that can be killed by antibiotics: strep throat?</p>
<p>One caused by a parasite: malaria.</p>
<p>Smallpox is the onei n government labs, and strep throat is the one that can be treated with antibiotics. Protist = malaria (Plasmodium), and malaria is also the most devastating...think of all the little kids in Africa.</p>
<p>Strepthroat, ryanberry you're right about that.
But i still think the greater killer is malaria.
in google malaria sounds mroe serious.
Let's move on to other questions</p>
<p>I've got couple questions I wasn't sure about:</p>
<ol>
<li><p>The location of reproduction organs in the grasshopper:
All the way in the back?</p></li>
<li><p>The disease causing the greatest number of deaths:
Hemophilia?</p></li>
<li><p>What happened to the A and a frequencies in the insects that could/could not metabolize the insecticide:
The A and a frequencies evened out?</p></li>
<li><p>Which can account for the difference in bristlecones and sawgrasses on the other slope? I. Nutrients in each soil type. II. Moisture held by each soil. III. Climate due to elevation.
I&II? Sawgrasses and Bristlecones grew at all elevations...</p></li>
</ol>
<p>5.What is an advantage of asexual reproduction:
Mutations are not passed from generation to generation? The rest didn't seem to make sense, though this doesn't sound too right...</p>
<p>6.Which is true of all ecosystem? (can't remember the exact wording)
Decomposers are an important part of the ecosystem.</p>
<ol>
<li><p>Faster motility is associated with what:
Biradial symmetry?</p></li>
<li><p>Sickle cell is caused by:
Improper protein being formed?</p></li>
<li><p>Cowpox vaccine eradicated small pox because:
They are similar and it trains immune system agains smallpox?</p></li>
</ol>
<p>10.Why is the centromere needed for the plasmid to be passed on?
Centromere allows formation of mitotic spindle?</p>
<p>so, when do the scores come out?</p>
<p>February 15th, I think...</p>
<p>For the one involving faster motion, I put bilateral symmetry, not biradial.</p>
<p>Bilateral sounds right... damn..</p>
<p><strong><em>, was cowpox vaccine thing one of M questions?
i don't remember solving that...</em></strong>;</p>
<p>I don't think centromere creates mitotic spindle,
mitotic spindles are actually created from centrioles, i believe?</p>
<p>(biradial is like, sea anemones)</p>
<p>Greatest number of deaths is malaria</p>
<p>Cowpox vaccine was part of the regular 60 questions....</p>
<p>I didn't take the test, but your cowpox vaccine answer seems correct. It was the first time anyone thought to vaccinate people using a similar but harmless virus.</p>
<p>What about the question that asked something like what didn't helped blood get back to the heart? I put voluntary vein contraction, because I don't think you CAN contract them voluntarily, but it might have been contraction of the diaphragm...</p>
<p>Lying down is the answer, since it does not help proper blood flow. Right?</p>
