<p>That is correct djumper168</p>
<p>The gamete one was AB, ab, Ab, and aB right? I know that’s it, just kind of a weird question.</p>
<p>yes djumper168. and i dont believe we ever reached a conclusion regarding the underwater plants and the temperature change, considering nobody seems to remember the exact wording of the question</p>
<p>^yea, you are correct!!</p>
<p>xscubastevex, I zealously think that it’s the enzyme option!</p>
<p>The correct wording was “Which of the following statements best explains why more oxygen was produced when the temperature was increased by 5 degrees Celsius?” I said the optimum temperature for the enzymes, but was unsure if it could have been about the warm water oxygen content change. I think E is a correct statement, but irrelevant on a photosynthesis lab, compared to if it were a dissolved oxygen lab like Lab 12 in CliffsAP.</p>

<p>read post # 199!
They agreed that it was photolysis!!</p>
<p>Unfortunately, that was a different question I believe. I think that was the one where they asked where oxygen is produced (We haven’t discussed this one btw). It was in the inner membrane of the thylakoids, right everyone? The other choices were stroma (that’s where the Calvin cycle is), two parts of a mitochondria, and a very wrong other choice.</p>
<p>This question we’re discussing did not mention photolysis.</p>
<p>yeah djumper, i put inner thylakoids. though the answer isnt a very good one, it was the only one that made sense considering the calvin cycle is in the stroma</p>
<p>^aren’t we talking about the one with the enzyme!! It said, " the higher temp is closer to the optimum temp of the enzymes used in photolysis." Correct me if I am wrong!!</p>
<p>HAHA!!</p>

<p>HOPEFULLY this question has been settled now that we have seen it in print. Also if you notice, the plant discussed in the article is Elodea, a water plant. And this experiment on the test was in water.</p>
<p>^nice one djumper168!!! high five!!! :D</p>
<p>Now talking to the two people in this thread besides myself who took E, gregbob and one other, why did you choose I, II, and III? I was obviously correct because if you don’t know mutation changes viruses, then you shouldn’t bother taking this test. But I didn’t really understand the other two choices. </p>
<p>II was dissemination… something something something. What did that have to do with change? Though I can see this as a possible choice, I have never seen the word in a biology book (possibly once), so I just wouldn’t see this as a logical choice. But who knows, maybe I’m wrong. I would really love to remember the correct wording of this choice if anyone remembers.</p>
<p>III was about how the viruses could go from small to large populations. Viruses can obviously do this, but I don’t think this would cause change either. Hardy-Weinberg theory states that rate of change is less in a large population, so this choice would defy the theory.</p>
<p>I could possibly see this being I and II only, but was this an option? I remember the choices being I only, I II and III, and three others I cannot remember. For now though, I believe the answer is I only until I am disproved.</p>
<p>I have also been googling for that pine one but cannot find much. I could really see this being the rocky soil or rate of evaporation, but E just sounded very “logically worded”. I could just see that phrase showing up in a biology textbook.</p>
<p>^ for the pine one what was answer choice E??</p>
<p>Also, for the virus one I thought that II and III kinda said the same thing! I thought that in a large population the virus would evolve and make new diseases as the individuals slowly gained immunity! aka since people would eventually gain immunity(natural selection) the virus would have to evolve and make new diseases!! But, I may be over analyzing! :(</p>
<p>No, you’re going into bacteria and antibiotics stuff where one individual is resistant, reproduces, and eventually all are. This is something entirely different. I say I is right, II is undecided, III is wrong. Just look at Hardy-Weinberg theory for that one. Large population = stable.</p>
<p>As for the pine tree question, C was rocky soil, and E was the precipitation would evaporate too quickly for the pines to utilize it.</p>
<p>I look back on the pine and HIV questions and just wish I had taken an extra minute on each. :(</p>
<p>The general consensus for the pine tree was ROCKY SOIL. If you go back a couple lot of pages, it’s there</p>
<p>For the photosynthesis question with the plants in the jar, the general consensus was enzymes</p>
<p>I put all three for HIV</p>
<p>Another question- prokaryotic and eukaryotic cells both possess- ribosomes, correct?</p>
<p>But grover, can you back up your reasoning on II or III?</p>
<p>Viruses are very good at mutating to different forms, which evade the immune system.</p>
<p>Best examples: the common cold (rhinovirus) and the influenza (the flu…orthomyxovirus). Both are RNA viruses that have really bad ability to handle transcription properly. With the cold virus, it mutates so rapidly that in the course of your lifetime, you will most likely never get the same ‘cold’ again, but mutated versions. In fact, it mutates so rapidly, that by the time you sneeze, you are sneezing mutated forms which are different from the virus that got you sick in the first place.</p>
<p>So, in a large population the virus would have an even greater prospect for mutation since there would be more aggregate cells to use the lytic/lysogenic cycle on!!</p>
<p>There are two principal sources of new viruses:
(1) old viruses that mutate into new strands, and
(2) viruses acquired from animals.
Many forms of flu and common colds originate in Asia and, in particular, in China. There, people often live in close proximity to livestock. Ducks, pigs, horses, chickens and other farm animals sometimes pass to a person what-had-previously-been a virus absent in humans. With dense populations in the region, it does not take long for the new disease to spread through Asia and then the world. </p>
