<p>Hey guys, what’s the answer for the excessive phosphates in lakes again? Is it pollution? Do we have another choice like eupho… something?</p>
<p>Was synapsis the odd one out in the chromosome mutation question? And who remembers the Q about an ecological niche or habitat or something?</p>
<p>was there a diagram with blue whales and a killer whale at the top or was that E only?
if not, does anyone remember any questions about it?</p>
<p>and a previous search shows that someone predicted -5/6= 800; is that a raw score of 74/75 or 5 or 6 wrong? 5 or 6 wrong seems a bit much; what would a 3 omit and 2-3 wrong be?</p>
<p>Hopefully 770 780 790(too high?)
Is a 770 or 780 good?</p>
<p>sooo here’s an updated version:</p>
<ol>

<li>Muscles and lactic acid (in anaerobic respiration) is similar to what
happens with yeast, when it makes ethanol</li>
<li>Gamete in plants = spore</li>
<li>Birth control = stops ovulation because it blocks progesterone</li>
<li>Krebs makes the most CO2</li>
<li>If a population is drastically reduced, random changes in allele frequency is most likely to occur</li>
<li>The cell life for the graph question was 40 hours</li>
<li>The karyotype indicated down syndrome in a female</li>
<li>Sugar is the dependent factor in the experiment with the amylase</li>
<li>The organism that the amylase is from was most likely from a hot spring because it functioned optimally at very high temps</li>
<li>Denaturation would most likely change the 3d structure of the amylase</li>
<li>The cuticle is the lipid layer that stops water from exiting the plant</li>
<li>The guard cells control the stomata/gas exchange</li>
<li>Epidermis covers all vertebrae</li>
<li>Hair does the thing with temperature and wind for mammals</li>
<li>Overheated power plant is because of pollution</li>
<li>Phosphorous is pollution too</li>
<li>Skin cancer is related to Ozone depletion</li>
<li>influenza is a virus </li>
<li>radial symmetry - cnidarians</li>
<li>property of water evident in capillary motion in tree trunks: cohesion</li>
<li>chromosome mutation: the odd one out was synapsis</li>
<li>color blindness is sex linked recessive</li>
<li>sexual reproduction is better because of genetic variability</li>
<li>pyruvic acid is made during glycolisis</li>
<li>natural selection does not include that acquired traits are passed to offspring</li>
<li>endosymbiotic theory - because mitochondria and bact. have the same RNA</li>
<li>independent assortment of cut leaf plants/other traits with actual data</li>
<li>lysosomes are used in hydrolysis</li>
<li>Transcription: making RNA</li>
<li>Splicing: taking out introns</li>
<li>Replication: refers to “semi conservative”</li>
<li>Pores in nuclear envelope: so that RNA can move out of the nucleus for translation</li>
<li>Elephants and giraffes and such live in the savannah</li>
<li>the sum of all an organisms interactions within a community refer to its “niche” </li>
<li>biomass decreases as it goes up the food chain because the energy is consumed</li>
<li>roots grow downward: gravitropism aka geotropism</li>
<li>plants leaning towards light –phototropism</li>
<li>bacteria moving toward food = taxis</li>
<li>Why shouldn’t you put any nutrients in a group of three plots for the experiment? to have a comparison group (control)</li>
<li>What does the data from the above experiment indicate? its best to use both phosphorous and nitrogen nutrients</li>
<li>What process changes atmospheric nitrogen to usable nitrates etc? fixation</li>
<li>Kingdom contains all the other categories like class, genus, order </li>
<li>Autonomic system controls heartbeat</li>
<li>catylase and hydrogen peroxide problem: add hydrogen peroxide</li>
<li>parents can be either A and A or O and O (I and III)</li>
<li>The branch will remain at 1.5m </li>
<li>biomagnification – when something gets more concentrated higher up in a food chain</li>
<li>Something about energy releasing reactions – I and III. (Anyone remember the actual choices?)</li>
<li>eukaryotes v. prokaryotes – lack defined nucleus </li>
<li>picture of structure of amino acids – it was protein</li>
<li>as you approach carrying capacity, density dependent factors will limit population growth</li>
</ol>
<p>does anyone remember the M question with the light spectrum or whatever that asked about a specific wavelength like 10^3 nm or something?</p>
<p>wait you’ve yet to explain why a sudden population drop results in random shift in allelic frequency and not that it’s more susceptible to mutation pervasion</p>
<p>^thanks,nice list</p>
<p>Thanks nritya!</p>
<p>I’m taking the test in Dec.
I have already read the whole PR book and am currently in the middle of Barrons, yet there still seem to be things in the nritya’s list that aren’t covered in any of those two…can you rec me how to prepare <em>please</em>?</p>
<p>If you have time and intend to take biology-related majors, find yourself a copy of Biology by Campbell.</p>
<p>@dasheeky:
When a catastrophic event occurs, it immediately affects the population, not individuals; thus, the allele frequency within the population would be affected almost certainly and instantly. There’s no guarantee that mutations will occur because of it, even later on.</p>
<p>Did anyone take E</p>
<p>^ like, one person.</p>
<p>btw i think evidence that mitochondria and bacteria are similar is because of their membranes and not RNA</p>
