<p>What were the options for the tapeworm? Toxins, offspring and what else. I don’t think it was the presence of a digestive system… Also, are you sure they produce a lot of offspring?</p>

<p>NYCKevin…part III actually said: “don’t have digestive system”, so you were right even though it was by accident</p>

<p>Why convergent isn’t it homology? Convergent doesn’t make sense</p>

<p>imaboss… Wow seriously? Awesome, i thought it was that they did have a digestive system</p>

<p>Convergent because they’re not from the same ancestor, but adapted for the same function</p>

<p>Crap wait it was convergent I read the darn question wrong :(</p>

<p>Which would change alleles in a population? Mutation and natural selection were two choices. </p>

<p>A couple that has a child already has two daughters. Is their chance for a daughter still 50%? (I dont think previous genders affect upcoming ones)</p>

<p>50%
Mutation was correct.
Tapeworms have a lot of offspring?</p>

<p>Mutation, 50%</p>

<p>No idea… Seemed right.</p>

<p>Guyyss do tapeworms produce many offspring? I don’t think they do…</p>

<p>Could -3 be 800??</p>

<p>yes tapeworms do produce a lot of offspring. They come out with the host’s feces.</p>

<p>looks like they lay many eggs to guarantee survival of some of the offspring.</p>

<p>They do. Heh I googled it right when I got home: [tapeworm</a> (parasitic flatworm) – Britannica Online Encyclopedia](<a href=“Tapeworm | Parasitic Flatworms, Anatomy & Life Cycle | Britannica”>Tapeworm | Parasitic Flatworms, Anatomy & Life Cycle | Britannica)</p>

<p>“The pork tapeworm (Taenia solium, or Taeniarhynchus solium), found wherever raw pork is eaten, lives in the human intestine in its adult stage. Each proglottid, following fertilization, may contain as many as 40,000 embryos encased in separate capsules.”</p>

<p>Cant remember which one I put for tapeworms. Hoping it was all 3. Anyway, could -3 be an 800 or would that be too lenient for M</p>

<p>I spanked that test so hard it ended back in the Holocene era. 1 wrong 79 correct.</p>

<p>Haha well -2 for me if I put all three for the tapeworm. Just in case, how will the curve be?</p>

<p>Seems like 2 incorrect and 7 omitted for me. Hopefully that’s enough for a 750.</p>

<p>Gaah I’m gonna be so ****ed if tapeworms got in the way of an easy 800 :(</p>
