**OFFICIAL SAT Biology E/M June 2013 Exam**

<p>What did you get on the one which said something like</p>

<p>What happens when you inhale</p>

<p>damn im at -5. can anyone predict that score?</p>

<p>so far only -1 :)</p>

<p>@thetester it moistens</p>

<p>What will the curve for M be like? It was much more difficult than E i heard…</p>

<p>nonono i mean like what happens in the lungs and stuff</p>

<p>I said diaphragm relaxes, but that’s wrong</p>

<p>@thetester I put something with thoracic cavity and negative pressure</p>

<p>@thetester123 lung muscles contract</p>

<p>I don’t remember a question on lungs… ? Was it in E? The difference between the atmospheric air one, and the air in your lungs, was that it humidifies, though.</p>

<p>Low pressure in lungs so air outside (high pressure) moves in.</p>

<p>i got thoracic cavity and negative pressure too</p>

<p>the lungs one was negative pressure in thoracic cavity, im 100% sure</p>

<p>What were the answers to the frog oocyte questions?</p>

<p>i got cloning for that and intestine cell does not degrade development something for the next one i dont remember the question word by word</p>

<p>I said that the frogs were cloned, that the frogs would be genetically identical, that older cells still have the ability to control development. That’s all I remember.</p>

<p>yeah i put that too</p>

<p>What about the one with pronuclei and two embryo something?</p>

<p>This test was kind of hard. I’m pretty sure I got above 700 but I was really hoping for 750 and M was hard</p>

<p>What were the answers to the questions about the frog embryo? Was did the experiment show?</p>

<p>Do you think the curve will be -3 or even -4</p>
