<p>iceberg
i think ur right (i got it wrong)</p>

<p>do you guys remember the quick short questions in the first page or so other than the eye, hair, bristle, cuticle, epidermis
did we miss anything?</p>

<p>what’s 3 omit 2 wrong? do I have a chance at a 790 or an 800?</p>

<p>^probably not 800 :/. 790 maybe</p>

<p>Wow… Looking at the eye, I guessed and got all 3 right O_O</p>

<p>how do u guys think the curve would be?
harsher? nicer? decent?
how many wrong is usually over 750?</p>

<p>ohh right guys
what causes influenza? remember that question in the first page?
the choice were i think : bacteria, virus, fungi, etc not sure though</p>

<p>virus^
d.fjshdfkjshdfjk</p>

<p>I said virus… But I donno the answer o_O</p>

<p>@iceberg
for the amylase problem (the one about rate of sugar production in terms of pH and temp) did you have hot spring as the answer for where it can be found?</p>

<p>how about the birth control one? (is it preventing ovulation or progesterone that affects uterine lining)</p>

<p>ntryia, i dont agree with all of those

<a href=“http://www.masseyeandear.org/for-patients/patient-guide/patient-education/diseases-and-conditions/cornea/function/[/url]”>http://www.masseyeandear.org/for-patients/patient-guide/patient-education/diseases-and-conditions/cornea/function/&lt;/a&gt;&lt;/p&gt;

<p>which ones are wrong?</p>

<p>wait if a population suddenly decreases, wouldn’t it be more susceptible to pervasion of mutations?</p>

<p>@nytria
did we confirm that malaria caused by a parasite?
the answer choices were something like (herbivore, carnivore, parasite, autotroph, or heterotroph)
wiki says that malaria is caused by protists (which can be both authotrophic and heterotrophic depending on whether it is amoeba, euglena, paramecium, etc)
…</p>

<p>^^Not necessarily. But allele frequency within the population would almost definitely change.</p>

<p>^^“Five species of the plasmodium parasite can infect humans:”
Either way, it’s a parasite that causes it.</p>

<p>why not, less organisms, more interbreeding, one mutation can be passed more quickly affecting a larger portion of the group</p>

<p>the question was not what CAUSES malaria… its what the malaria is. malaria lives off of humans and can survive by attaching itself to humans, but by doing so, it causes “damage” to them. therefore malaria = parasite.</p>
