<p>the thing is the test is graded on a positive scale where they ignore the incorrect details that you give and only grade the correct parts.</p>
<p>hey, my teacher went over potential answers to the free response. i thought i did pretty well, but then realized that i messed up on the easiest part of the free response: calculating the rates for the last question. obviously i was really disappointed and angry. i am a little worried about my score now. do you think i will get 2 points if i should the correct work, but had the wrong calculation? also for the sexual reproduction one, I’m i right if i discussed crossing over, independent assortment, and random joining of gametes? i feel as if i interpreted the question the wrong way. it seems as if the curve is going to be really tough this year. the makes me even more worried.
worst come to worst, if a get 70 point on the multiple choice and have frq scores of 8, 8, 6, 5, what do you think my score will be? any answers are really appreciated!</p>

<p>For the frq, does cam photosynthesis and the sizes of plants affect transpiration?
Is mitochondria in eukaryotes comparable to pure glycolysis in anaerobic prokaryotes?
What about golgi and vacuoles? Or nucleus and nucleolus?
Sexual reproduction variability independent assortment, crossin over<br>
and gamete variability from spermatogenesis?
Intracellular roundworm, extracellular fungus?
Benefits of asexual, quick , identical copies, and can be done basically anywhere?</p>
<p>Thanks for answers</p>
<p>“Answers must be in essay form. Outline form is not acceptable”</p>
<p>um were if i did something like this:</p>
<p>Mitochindria: 5 sentences of description.
Ribosomes: 3-5 sentences.
nucleus: 3-5 sentences</p>
<p>like its not really outlined with bullets and stuff, but not necessarily essay form. plus i didn’t separate the two with spaces, i wrote the following thing on the following line. this is for coherency for me, and should be for the grader as well. man if i get a 0 on all my frqs for this then im f*****. should i email CB? plz reply.</p>
<p>You didn’t even get your score yet and you’re already stressing… Calm down…</p>
<p>why would i stress after i got my score? tensions gone by then. but whatever haha, but yeah do u thinks it fine or will this jeopardize my score? </p>
<p>and for the rate questions, were we supposed to use specific coordinates and find slope?</p>
<p>Would a thinner xylem lead to faster transpiration given that whenever water leaves the surface, the water would travel up faster due to capillary action , thus, speeding up the whole system?</p>
<p>Hey, the factors that affect transpiration are included in Lab 9, such as humidity, wind, temperature, light: you should elaborate by discussing the stomatal opening and closing mechanism etc. </p>
<p>My question is: Did anyone here get free response questions other than the Form B ones? I got two questions about ecology (one in which we had to design an experiment not related to the 12 labs) and one about evolution (maximum parsimony, phylogenetic trees and stuff). The first FRQ was about cell division (definitely the easiest), but I personally thought the other three were a bit difficult. After reading your posts, I think the Form B FRQ were way too simple. Unfortunately, I didn’t take the test in America. </p>
<p>Please reply…</p>
<p>Yeah. Everyone in North America got the regular version of the FRQs.</p>
<p>Anyway, what organelles did you guys list for the first question? I listed ribosomes, mitochondria, endoplasmic reticuli, and Golgi apparati. However, I kind of BSed the second part where the question asked to list how prokaryotes carry out the same functions. Do you guys think plasmis and chemosynthesis will net me any points? O.o Essentially, I argue that plasmids allow the exchange of DNA with the outside environment much in the same way that the Golgi apparatus allows the exchange of lipids, carbohydrates, and proteins with the outside environment.</p>
<p>For the transpiration rates, I got .14 and .24 (or whatever multiple of 10 it was for the unit). Any of you guys got the same? Also, for transpiration rates, I argued CAM photosynthesis and the size of the cuticle layer because I couldn’t think of anything else. Any thoughts as to whether those will get credit?</p>
<p>i got .13 and .24, theres a .01 diff for one of our answers but i doubt they’re looking for accuracy. for transpiration i also put the cuticle one with how one could have a thicker cuticle. i also put one couldve been a bryophyte and the other couldve been a regular vascular plant and talked about xylem.</p>
<p>For me, I received .14 and .24 also for the rates…</p>
<p>yea, i got .25 and .15</p>
<p>I freaking out too! Is it really based on a curve on how good everyone does? I heard a lot of people say that the exam was REALLY EASY (except me) and that they’re going to get a 5! This is scaring me. Does that mean that the curve will be very bad this year, like instead of getting what would be a 4 you would get a 3 and get a 4 for what could’ve have been a 5?<br>
I messed up on transpiration because I forgot the decimal!!! Would I still get part marks? Mine was roughly in the same as what you posted (but with the different decimal place). Is fungus extracellular digestion?</p>
<p>What score range do you think would be needed to get a 5? (roughly how many multiple choice right and how many points on the free response?)</p>
<p>Is the plasma membrane an organelle? </p>
<p>Sorry for rambling but this exam is really getting me paranoid. If someone could help answer my questions I’d really appreciate it. Thanks</p>
<p>For Question 1. B, did any of you guys discuss about the cell wall of the prokaryotes, and how it is composed of peptidoglycogen, and gram- and gram+… and nucleiod region in the plasma membrane contains genetic information, and ribosomes.</p>
<p>and for 2. B, did you any of you chose stomach and write about how it has smooth muscle which allows for contraction, and the mucous membrane?</p>
<p>for 3. b, did you any of you chose mutation, crossing over, and I was a little iffy about this one, about how their are so many ways for the genes of a human to be selected due to 23 chromosomes from your father and 23 from mother.</p>
<p>and finally for 3. C, I got this one wrong I know but was just wondering if you any of you drew a diagram or picture of a sperm cell (haploid) + ovum(Haploid)=diploid feritilized zygote (for Humans in particular) and then did you guys give an example of like a monkey, and how its prezygotic (sperm cell (haploid) + ovum(Haploid)=diploid) differs because maybe the sperm cell is not diploid and there for the zygote is different therefore it causes sterility!</p>
<p>2b) I wrote the same thing as you. I mentioned how the muscles of the stomach wall help churn the food into smaller particles. I also said that the mucus membrane protects the wall from corrosion by the hydrochloric acid (or more specifically, the activation of pepsinogen).</p>
<p>3b) I pretty much restricted my argument to how the process of meiosis, since it is a component of sexual reproduction, results in genetic diversity. For my three points, I discussed crossing over, the law of independent assortment, and random mating. The latter doesn’t really much to do with meiosis specifically, but it does increase genetic diversity.</p>
<p>3c) I discussed temporal isolation and behavioral isolation.</p>
<p>I got .23 & .15 ?
I said cam, thicker cuticles, and surface area od the leaf…and i also vlisted ribosomes, the golgi, mitochondria, and the nucleus and said that prokaryotes have mitochondria, smaller ribosomes, and just have geneticmaterial in the form of plasmids or just suspendedin the cytoplasm…</p>

<p>Don’t prokaryotes have larger ribosomes? Or am i just being stupid…</p>
<p>They have ribosomes, but I am pretty confident that they are smaller than those of eukaryotes.</p>
