<p>Alright cool thats what i was thinking too.</p>
<p>Also this is from wikipedia about unlinked:
</p>
<p>what about the epithelial cells in the gut?
i put extracellular matrix, but i think i might be tight junctions.</p>
<p>I think its tight junctions. wait so it was all four gametes?</p>
<p>@141421356 Yes you are correct, i already found my mistake but thanks anyways.</p>
<p>i think the epithelial cells were tight junctions, so as to prevent the leaking of stomach fluids, might be wrong though</p>
<p>Who thought this test was extremely hard and had nothing to do with biology???</p>
<p>Arthropods most successful and Notocord = Chordate</p>
<p>Substrates was confusing, but the other choices were not really reasonable.</p>
<p>tight junctions. Read that in sparknotes ap biology review book this morning coincidentally.</p>
<p>@bobhewitt I thought it was more thinking based rather than fact.
@141421356 Yea substrate looked like the best one.
Hopefully i only got -3 on this</p>
<p>Wait was flagella an option? If so wow. I really failed.</p>
<p>and If it was cillia then its true:</p>
<p>cilia are found only on certain cells in the vertebrate body, e.g., the epithelia lining the airways.</p>
<p>LOL @1414, I put the flagella and i feel so stupid about that one now… lol</p>
<p>THATS very dumb of me, worst mistake EVAR! :'(</p>
<p>wait, wa the answer flagella</p>
<p>can someone put up a general range of approx. what -3 is, -5, etc? What’s the most wrong for a 700?</p>
<p>“Tight junctions join the cells of the small intestin to prevent substances from leaking into other parts of the body” Quote taken from Sparknotes: Guide to AP Biology</p>
<p>No, bc epithelial tissue doesn’t need to move around. lol the answer is tight junctions</p>
<p>Shoot. What were the choices for the mammal/marsupial.
It was long gestation. </p>
<p>OMG>.<</p>
<p>and yeah of course. No cell in the body really has a flagella. :(</p>
<p>what was the mammal marsupial one?
i put fully developed at birth or something.</p>
