<p>@bigdream yup</p>

<p>@bigdream18 right, i put the letter closest to the beginning and the original letter that started that branch.</p>

<p>Same. I had D&E, and went with blood transfer for placenta question. I also put thymus to the question about immune/endocrine system. For E takers, did anyone put that 1500m had less growth on the second to last question?</p>

<p>i put secondary sex characteristics for the not maintaining homeostasis one. :/</p>

<p>Yes, the trees at higher elevations grew slower than the others.
What was the answer to the solution to the experiment? More data points?</p>

<p>Kdines, I’m pretty sure that is what they meant.</p>

<p>i did thyroid for that one i believe, (could be a diff question than what your talking about though), and idt it was 1500 had less growth bc at 500 it only grew 3.4 or something and that was second least. i forgot what i put for the answer though.</p>

<p>I had more data points, and then changed it to they should measure temperature. I wasn’t sure at all though.</p>

<p>@ChickenFriedRyce lol, ur right for that other one, and i did more types of trees, since they only tested the one species for the last question.</p>

<p>Kdines, you had to take into account the age of the trees at time of measurement. The trees at lower elevations were younger.</p>

<p>I put they should measure temperature as well</p>

<p>Which one?</p>

<p>@ChickenFriedRyce true, good point. and its the last question were talking about.</p>

<p>How about the one with the red blood cell and water?</p>

<p>@kdines95 I’m pretty sure it wasn’t more types of trees because the purpose of the experiment was to test how this particular specie reacted to different variables.</p>

<p>Balsam firs are evergreen trees, temperature has no effect…</p>

<p>RBC would swell</p>

<p>This is a dumb question, but CO2 increases because fossil fuels are burnt right?</p>

<p>Yes. If your talking about the global warming question, I put that the tree would grow faster because of the increased CO2</p>

<p>yes agree with MMAfAnatic9</p>

<p>what else was there?</p>

<p>was wind the answer to the one about how a seed gets spread from a flower with no fragrance?</p>
