<p>it was def ostrich, ughh as this thread progresses my score decreases and my folks told me i cant cancel nada cuz im a bum haha</p>
<p>don't... it's better to die a hero than live a coward. if you get around 700, it's still not bad.</p>
<p>The answer to the ear question is basilar membrane.
<a href="http://en.wikipedia.org/wiki/Ear%5B/url%5D">http://en.wikipedia.org/wiki/Ear</a>
" The cochlea is wrapped in a spiral shape and also contains the coiled basilar membrane, which resonates preferentially in different locations along its length depending on the frequency of the impinging vibrations. When a region of the basilar membrane resonates, the hair cells in that region send nerve impulses to the brain, which are perceived as a sound of whatever pitch the hair cell is associated with."</p>
<p>Hm, so getting fifteen wrong is the cut off for a 700, right?</p>
<p>If you attempt all questions, what is the maximum questions you can miss and still guarantee a 800?</p>
<p>Wait so is the basilar membrane the answer: A?</p>
<p>If so WHOO HOO! </p>
<p>I put the one that vibrates at different frequencies.</p>
<p>However I missed the one about menstration :(.</p>
<p>The Starch question. It SAID the membrane was ONLY permeable to water. which means the starch amount does not change right?! or was it concentration :(</p>
<p>it asked about starch concentration adn starch concentration decreases because water goes in and dilutes the starch.</p>
<p>Yeah, that was tricky. I was <em>this</em> close to picking the 'no change' line.</p>
<p>more questions:
what were the first land organisms (bacteria?)
what was the purpose of the carrot lab
what was the control for hte carrot lab
why did the carrots become more flexible
why did the carrot on thge counter sprout and the one in the refridgerator didnt
what would be a control for the experiment with the agar and the bacteria and the 4 antibiotics
what is necessary for oxidation</p>
<p>oxidation= electrons
control= paper plate with no antibiotics
Carrot= Light
forgot the rest haha</p>
<p>i put ions i think mine is wrong</p>
<p>Oxidation-reduction (redox) reactions involve the transfer of electrons.</p>
<p>Yay for Chemistry... :p</p>
<p>damitssam</p>
<p>if the control has no agar, it wouldn't work would it?</p>
<p>the ear is the ringing of different sections of the cochlea .. yep ... or it said something like that in the kaplan sat ii bio book. check it out</p>
<p>i went through all 12 pages and if you guys are right about ur answers, 800 here i come</p>
<p>oh its basiliar membrane according to wikipedia..awesome i guessed right</p>
<p>zero87, i put cochlea because i know that it transmits different things.</p>
<p>that is a weird question...</p>
<p>the carrot becomes flexible because it's flaccid.... basically, the cell member moves away from the cell wall.</p>
<p>if it had a ton of water, it would become turgid, and be stiff.</p>
<p>i think i said that just out of a common sense type of thing
i think i put ions for redox ughh</p>
<p>If you attempt all questions, what is the maximum questions you can miss and still guarantee a 800?</p>
<p>look at the other thread...</p>
<p>dunno 6 or 7</p>
