<p>the one growing around the stake was touch, no?</p>
<p>commensalism was the cow and the egret</p>
<p>and meadow its not light it was definitely gravity… the shoots of the seeds were all pointing down (and the experiment took place in the dark anyway)</p>
<p>For the plant lab, didn’t it say that the petri dish edge was in the dark? Or something of that sort? What did that mean?</p>
<p>And btw, tapeworms don’t have a digestive system</p>
<p>It said that the entire petri dish was in the dark in order to control the experiment for light. Thus, we know it’s a gravitotropism (also, the experimental text said that the petri dish was taped to the wall at a 90 degree angle, and that was the direction of seed growth).</p>
<p>^^ yeah. but do they reproduce fast or not?</p>
<p>Ichiruki: Really? I remember it saying that the entire petri dish was in the dark. now second guessing myself…</p>
<p>Ah, did not read experimental text. In that case gravity makes most sense.</p>
<p>is the 2nd one with the stake thigmotropism ?</p>
<p>NNS - yes. If you read the last page, you would know that.</p>
<p>^Yes. 10char</p>
<p>i feel like i got at least a 750</p>
<p>the first question about some bird and the rhino with the virus was mutualism right?</p>
<p>Damn, I really thought I saw the word edge somewhere in the explanation, making me believe that there was light and dark in the experiment.</p>
<p>And yes, it was mutualism.</p>
<p>^Yea same. Since it said I thought edge meant it was in some structure so the out of the edge there would be light. But behind the edge there would be no light. Confusing…in a sense.</p>
<p>Oh and and I can’t believe I missed the bird question. Due to apparent brain freeze, I believed that birds didn’t have beaks thus must have teeth lol</p>
<p>does anyone remember the question about Huntingtons? who must be affected?</p>
<p>^ I said 50%.</p>
<p>I put 5 and 6 for the carriers because they were the parents. The disease was recessive, so his parents (5 and 6) had to have both been heterozygous, judging from the pedigree.</p>
<p>right, but another one - who must carry the disease? listed two individuals. I put 5 and 6 but I believe that’s wrong.</p>
<p>5 and 6 is correct 
Since its recessive both parents must have a recessive allele for the child to have the disease.</p>
