<p>hmmm i thought i put internal development but i might be wrong about that</p>
<p>Ok wat about the one that asked “according to evolution, how do we vew embryo developement?”</p>
<p>I was between it was identical in all mammals and it was more similar for more closely related species…I think the latter was the obvious and correct answr…but idk</p>
<p>oh it was the long gestation period</p>
<p>for the embryological development one, i put differences (not all identical, that would just be crazy)</p>
<p>damn it, that’s -3 now (-4 due to stupid .25 off). any chance that would still be an 800>?</p>
<p>Idk…for vertebrates the formation of embryos follows a pritty standard development…isnt fetal development where it starts to get really different</p>
<p>was it compare dna for distinguishing the two crab species?</p>
<p>the embryo, it was closer related animals have more similar embryological development</p>
<p>wait tinks is that referring to my question or sum1 else’s?</p>
<p>someone elses. yes it was dna dont worryy =)</p>
<p>Wasn’t it DNA?</p>
<p>well it says mammal embryos begin to look different as organogenesis begins… so i didn’t assume they were all the same</p>
<p>oh yea the marsupial q…
that one was hard; i just chose internal development, but i really had no clue
its weird cuz marsupials never showed up on any practice tests i took :/</p>
<p>Dang then I missed 2 questions so far = (…</p>
<p>Wikipedia says the following about Marsupials which implies that long gestation period is not the answer and that internal development is correct:</p>
<p>Pregnant females develop a kind of yolk sac in their wombs, which delivers nutrients to the embryo. Marsupials give birth at a very early stage of development (about 4–5 weeks); after birth, newborn marsupials crawl up the bodies of their mothers and attach themselves to a nipple, which is located inside the marsupium.</p>
<p>wait, whats the answer for the marsupial q?
edit: so it is internal?!?</p>
<p>they both have internl but marsupials are born early n then thy go into the pouch to finish development. so it is long gestation period</p>
<p>yea the marsupial one isn’t internal development, it’s the gestation period instead. ■■■■■■■■, we got asked some of the weirdest questions on this test. </p>
<p>felt like the first 60 questions were just one big Bio ecology section.</p>
<p>^^ agreed “felt like the first 60 questions were just one big Bio ecology section.”
i didnt even know what gestation meant on the test:/</p>
<p>Ok am I correct in this then:</p>
<ol>
<li>DNA was the answer for determining different crap species (got it wrong =/)…my problem with that answer was that one determines a species based upon their ability to interbreed and produce fertile offspring. Thus, one would need to analyze the morphological aspects of an animal to really get a direct grasp on that.</li>
<li>Marsupial one= internal fertilization</li>
<li>Homology= more similar=more related (got this one wrong)</li>
</ol>
<p>umm marsupial was gestation period…
i thought we just solved this
and what was homology? i dont even rememeber that on the test?</p>
