<p>what if for question 3b (?? about the prezygotic barriers) i /described/ two forms of isolation correctly but labeled them wrong? like instead of geographical isolation i said environmental isolation, and for mechanical isolation i said sexual isolation–would i still get points for my answers, despite the incorrect labels??</p>

<p>^its true, and they have chuck Norris working for them. Classic college board… :/</p>

<p>Oh boy, now that we’ve just called them assassins, they’re going to delete all our scores! :(</p>

<p>Will it be a problem if i put 20 in the form code?</p>

<p>I put the test code then put 20 after it.</p>

<p>For the prezygotic barrier I put the first barrier stops the formation of zygote and if the first barrier fails then the second barrier act in by making that hybrid animal sterile so they won’t be able to reproduce because they have underdeveloped gonads?</p>

<p>is this correct?</p>

<p>is nondisjunction a prezygotic barrier? (isolations are not the only prezygotic barriers)</p>

<p>i dont think nondisjunction is a reproductive barrier, its just an error during reproduction. doesnt stop two individuals from reproducing
test was easy</p>

<p>lol sorry but that is very very very wrong. </p>

<p>same for kbolivar.</p>

<p>For extracellular I put fungus and starfish, are they extracellular? I remember fungus break down organism outside with enzyme into nurtients and them absorb then and in starfish, they would open a shellfish, their intestinal organs would literally come out of their body, and they put it inside of a calm and use digestive enzyme to break down the internal substance of the shellfish and sucks everything back into itself? At first I thought extracelluar means outside but now after looking at it, it doesn’t mean outside so would fungus and starfish be right?</p>

<p>Wht wasthe answer to chi squared thing… I put b… Total guess</p>

<p>^The ap people are going to hunt you down and murder you</p>

<p>Yeah I just took one look at it and mouthed “what the f**k” and guessed</p>

<p>oh gosh… we werent allowed to discuss anything?</p>

<p>I’m not going to disclose anything specific to the question, but calculating chi squared shows you the chance of… Forget it, it’s too hard to explain without disclosing the question… And I don’t wanna get hunted down. But google magic might help?</p>

<p>The value has to be LESS than something, not greater.</p>

<p>Does College Board allows sutdents to take AP Biology test one more time (next year)? I think I did decent but not in 5 range…stuided wrong sections (studied Plant section very heavily)…</p>

<p>wait, you can get hunted down for this? omg, i’m so scared now, what do i do???</p>

<p>Were the last 7 questions hard? :frowning: I didn’t have enough time to finish those, so I just guessed with same letters…</p>

<p>I’ll ask once again. Would it be a problem if i put 20 after the form code?</p>

<p>@bilginsoy
I think I put it as well. I don’t think it’ll jeopardize our scores.</p>
