November 2010 - Biology (E/M)

<p>does anyone remember the question that had 2 traits
and asked what can we conclude
something about their being on the same chromosome?</p>

<p>Consolidated Answers:</p>

<p>Eye diagram:
1-Area around pupil controls light entering eye</p>

<p>2-The nerve exiting eye is part of the nervous system</p>

<p>3-The circular structure right behind the cornea focuses light onto the retina</p>

<p>Light spectrum:
4-Violet light is the highest energy one we can see</p>

<p>5-UV can cause mutations</p>

<p>6-Green is what chlorophyll can’t use</p>

<ol>
<li><p>PCR is used to amplify DNA</p></li>
<li><p>Penicillin comes from fungus </p></li>
<li><p>Sharks do not have a bony skeletal structure</p></li>
<li><p>Which are parts of energy transfer in ecology? I and III I. Plant
converse light energy to chemical energy. (I. Plants convert light to chemical energy III. Animals use plant as a source of metabolic energy.)</p></li>
<li><p>What is the correct hormone function pair? Cytokine</p></li>
<li><p>Polydactyl question – it can’t be determined based on the given info</p></li>
<li><p>The structural polysaccharide was cellulose</p></li>
</ol>

<p>Albinism section:
14-The dad HAD to be Aa</p>

<p>15-The kids could be 50% albino</p>

<p>16-The older son had to be Aa</p>

<ol>
<li><p>Malaria is a parasite</p></li>
<li><p>The flower and bee are in a symbiotic relationship</p></li>
<li><p>Muscles and lactic acid (in anaerobic respiration) is similar to what
happens with yeast, when it makes ethanol</p></li>
<li><p>Gamete in plants = spore</p></li>
<li><p>Birth control = stops ovulation because it blocks progesterone</p></li>
<li><p>Krebs makes the most CO2</p></li>
<li><p>If a population is drastically reduced, random changes in allele frequency is most likely to occur</p></li>
<li><p>The cell life for the graph question was 40 hours</p></li>
<li><p>The karyotype indicated down syndrome in a female</p></li>
<li><p>Sugar is the dependent factor in the experiment with the amylase</p></li>
<li><p>The organism that the amylase is from was most likely from a hot spring because it functioned optimally at very high temps</p></li>
<li><p>Denaturation would most likely change the 3d structure of the amylase</p></li>
</ol>

<p>Very first section:
29-The cuticle is the lipid layer that stops water from exiting the plant</p>

<p>30-The guard cells control the stomata/gas exchange</p>

<p>31-Epidermis covers all vertebrae</p>

<p>32-Hair does the thing with temperature and wind for mammals</p>

<ol>
<li><p>Overheated power plant is because of pollution</p></li>
<li><p>Phosphorous is pollution too</p></li>
<li><p>Skin cancer is related to Ozone depletion</p></li>
<li><p>influenza is a virus </p></li>
<li><p>radial symmetry - cnidaria</p></li>
<li><p>property of water evident in capillary motion in tree trunks: cohesion</p></li>
<li><p>chromosome mutation: anything but deletion, inversion, nondisjunction, and translocation</p></li>
<li><p>color blindness is sex linked recessive</p></li>
<li><p>sexual reproduction is better because of genetic variability</p></li>
<li><p>pyruvic acid is made during glycolisis</p></li>
<li><p>natural selection does not include that acquired traits are passed to offspring</p></li>
<li><p>endosymbiotic theory - because mitochondria and bact. have the same RNA</p></li>
<li><p>independent assortment of cutleaf plants/other traits with actual data</p></li>
<li><p>lysosomes are used in hydrolysis</p></li>
<li><p>Transcription: making RNA</p></li>
<li><p>Splicing: taking out introns</p></li>
<li><p>Replication: refers to “semiconservative”</p></li>
<li><p>pores in nuclear envelope: so that RNA can move out of the nucleus for translation</p></li>
<li><p>elephants and giraffes and such live in the savannah (YEAH!!!)</p></li>
<li><p>the sum of all an organisms interactions within a community refer to its “niche”</p></li>
</ol>

<p>^^I put something else for that one, but I don’t remember what it was.</p>

<p>@goldy
indenpendent assortment question:
data-
914
312
302
101
the following is independentently assorted and it is not in the same chromosome </p>

<p>yes it’s hydrolysis</p>

<p>nvm 9:3:3:1</p>

<p>Can we discuss the Ecology section?</p>

<p>@dasheeky
yes it was and it was in the first section (Q#1-60)</p>

<p>other answers continued for M section:</p>

<p>Transcription: making RNA
Splicing: taking out introns
Replication: i forgot (but it was easy)</p>

<p>pores in nuclear envelope: so that RNA can move out of the nucleaus for translation</p>

<p>other answers continued:</p>

<p>elephants, antelopes, and other animal live in SAVANNA YEAH!!!</p>

<p>What do you think the curve will be? How many can you get wrong and omit to get 800?</p>

<p>Is replication semiconservative?</p>

<p>^yes.
on the savanna one, that’s what i put.</p>

<p>@nwgolfer321
it sure</p>

<p>do u guys remember the problem about the relationship between an organism and its environment: wasn’t the answer something like “ecological niche”?</p>

<p>yep. from wiki:</p>

<p>Semiconservative replication describes the method by which DNA is replicated in all known cells.</p>

<p>I also put ecological niche.</p>

<p>Do you remember the last 6 questions about the algae?</p>

<p>^I’m pretty sure almost every one took Bio M, lol.</p>

<p>@TheMathNerd: I took bio e!
there were a few I wasn’t sure about but overall I thought it was ok…
I don’t really remember any specific questions though lol</p>

<p>does anyone remember that one about the jars and the chart?
what was the main source of energy?</p>

<p>other answer continued:</p>

<p>biomass problem: i put it decreases as it goes up the food chain cuz the energy is consumed or something</p>

<p>guys we’re pretty much dominating the SAT II board.</p>
