<p>thanks saroh this is really helpful </p>
<p>Keep posting </p>
<p>guys lets help her!!!!!!!!!!</p>
<p>i like the format nice and easy to understand</p>
<p>sarorah did you make a list of m section yet?</p>
<ol>
<li><p>In a small population, there are 6 rodents that possess a unique gene. In a thunderstorm, the 6 rodents are randomly killed. What is this an example of? Gene drift</p></li>
<li><p>Which of the following prevents fertilization? I and III, only
I. Blockage of the fallopian tubes.
II. High production of LH just before ovulation.
III. Too extreme of a pH in the vagina and uterus.</p></li>
</ol>
<p>For 18, shouldn't it be natural selection? If all the rodents with the recessive allele were killed, then they did not have fitness, so they were selected against, right?</p>
<p>For 19, it said that she was able to ovulate. If the fallopian tubes were blocked, how can you ovulate? </p>
<p>For the E section:</p>
<p>No. 61 had something to do with polyploid plants having a greater chance of a recessive allele showing than monoploid or diploid plants. I think. </p>
<p>There was a food web section, where the hawk and shrew(?) had a predator-prey and competitor relationship. The largest level was tertiary for the hawk, and the organism that could be primary and secondary consumer was the bird.</p>
<p>I disagree with 87. It was something else that I can't remember. And 88 was a genetic mutation right?</p>
<p>i agree with durt on both</p>
<p>The one with..</p>
<p>6 legs and exoskeleton..</p>
<p>that's insect right?</p>
<p>That's what I put. Insect I hope!!!</p>
<p>For question 87, I put that Solution 2 was comparable to the control solution, the water. I don't think that you can be 100% sure that it disintegrated the cell walls. Solution 3 could've stopped other cell processes or done something else. I just don't think that "Solution 3 disintegrated the cell walls" is the best answer.</p>
<p>why does e.coli have the system of activating galactidose at will?
answers were like
a) some people don't always drink milk
b) human intestine secretes lactose
c) lactose more toxic than galactisodase</p>
<p>answer: A</p>
<p>Why is it A? The only need for galactisodase is to BREAK DOWN carbs, so if you're not drinking milk (choice A), you won't need your lactose broken down. Unless I'm missing the point of galactisodase...</p>
<p>Are you guys sure that agglutination was the right answer to the bloodtype question? Also, I agree with dragonscale..I think I put II and III only, since III only wasn't an option. Yeah, and the question read something like "which of the following would allow an ovulating woman to produce an infertile child" or something along those lines...it wasn't fertilization, like you guys thought, but FERTLITY...I believe.</p>
<p>Also, dragonscale, it wasn't natural selection, because the key term was "randomly"...natural selection is a very systematic process..</p>
<p>for the question about the boiling of the leaf in alcohol: I put that it converts the glucose into starch so that the iodine(i think) stain could register the starch levels, since after photosynthesis, the sugar is glucose, not starch.</p>
<p>^ i also put starch, and i am almost sure it is right. Did it say anywhere that the plant was deprived of color? did it turn white? because i remember that it said the experimentor measured the starch level- and i assumed the alcohol converted the glucose into starch.</p>
<p>i also disagree that penicilin was derived from fungi. I thought it was bacteria</p>
<p>Anytime phd :)</p>
<p>penicillin was derived from fungi for sure. </p>
<p>H20poloer, I believe I put that too, it was a natural conclusion given the chart of the iodine/starch after boiling the cabbage in alcohol. </p>

[/quote]
This was my reasoning too however someone said they asked someone who was a molecular scientist blah blah . . i dunno, all of these "answers" are based on general consensus only, and a few of them can be proven.</p>
<p>87, I put that Solution 2 and the control were comparable, because that was directly related to the chart. Although Solution 3 COULD HAVE disintegrated the cell walls of the e.coli thereby making them unable to survive, too many other factors could have played in the death of e.coli.</p>
<p>But again, these are based on general consensus only. My answers also disagree on some .. </p>
<p>Agglutination was definently the correct answer, all of the others didn't make sense. You can check by reading the corresponding section in barrons, I specifically remember reading about it.</p>
<p>Zachsta, the answer is A because galactisodase is only activated when a lactose substance is consumed (i.e. milk). Some people don't drink milk all the time, so E.coli needs a system of turning on and off the gene.</p>
<p>for number 88: wouldn't the mutation be in the sequence of nucleotides, not the amino acids?</p>
<p>^ yeah that is what i think</p>
<p>For the alcohol burning one, I put destroy the cholorphyl, because it turned white, indicating a loss of pigments. Woulnd't the glucose all ready be stored as starch in a leaf without any burning process?</p>
<p>Yes, dark reactions is another name for the Calvin Cycle, but the name is misleading: the Calvin Cycle cannot not occur without products from the LIGHT reactions, so if there was no light in the experiment, that means no light reactions and no products for the Calvin Cycle to occur with. Therefore, no Calvin Cycle.</p>
<p>At least, it says the Calvin Cycle cannot occur without light in the Cliffs Book. [shrug]</p>
<hr>
<p>it cannot occur without the PRODUCTS from the light cycle. If it were placed in light for say ... 24 hrs and then moved to the dark for 24 hrs ... i think the calvin cycle would still take place?</p>
