<p>im pretty sure… cause i remember thinking… humans are chordates… and we dont have exoskeletons</p>
<p>I also got exoskeleton as the right answer (IE: chordatas dont have it)</p>

according to this C is secretion and reproduction and B is leg attachment?</p>
<p>A grasshopper is different though. If you looked at the picture, the legs should have been attached in the very rear.</p>
<p>i remember seeing the front (small) legs attached to the center and the big ones were ambiguously drawn so i said center</p>
<p>oh i must have been stupid then. because i know that. but i think i put something else.</p>
<p>I got this from the old thread, but AHHHH!

<p>yeah according to the link above, both the large jumping leg and the small legs are attached to the middle, or the Thorax and the reproduction/secretion occurs in the abdomen or the big butt thing.</p>
<p>****. it for sure looked like the big legs were attached to the “abdomen” on the test.</p>
<p>there was also one about veins. do you guys remember that. i put “veins cannot be voluntarily constricted” or something like that.</p>
<p>same, we don’t have any control of our veins… I don’t even think veins constrict anyway… that’s arteries.</p>
<p>agreed.</p>
<p>oh no, was the smoker’s thing “emphysema”? I had NO idea what emphysema was… I put black lung :(</p>
<p>I put black lung as well which was the WRONG answer…</p>
<p>shoot this curve better be nice</p>
<p>and i think the egg one is prevent dehydration. I think the question was, how did eggs adapt to survive on land? Yolk doesnt work, because all eggs, not just terrestrial eggs, have yolk.</p>
<p>anyone else already sign up for the december bio test? same.</p>
<p>I omitted 10, and I’m sure I got enough wrong to put me below 700.</p>
<p>^ Same here 
I’m really disappointed. I had omitted 11 before, but I went back at the end and I guessed on a couple more…so I ended up leaving 8 blank I think.</p>
<p>What was the curve like in January? Does anyone know?</p>
<p>Is SAT Bio always this hard or is this test an exception? I signed up for Bio and now I’m really intimidated…</p>
<p>This test was an exception. That is for sure. The curve was -5 points = 800 in January.</p>
<p>Apparently this test was the hardest one they’ve administered…yeah just my luck. December will prob be easier, but I wouldn’t hope on it. I’m not retaking anyway.</p>
<p>Yeah, alllll of them are easier than this one. This one just sucked big time. I hate how both my re-takes were this test. I canceled the first time too! Argh…</p>
