<p>the rat and DEC one… we discussed this earlier but i’ll recap:
1 The corn oil, i said, was given to rats that didn’t take DEC, as a control (don’t remember the exact wording of the answer, but something like that)
2 What the dots stood for, I said was avg % reabsorption for each level of DEC given
3 Which statement was true, I said more than 30micrograms of DEC was harmful to mice fetuses</p>
<p>idk probably, that ques made no sense
and oh oh ! what about the CO2 one??
did you put burning fossil fuels</p>
<p>oh i answered myself,
[Answers.com</a> - What gas is released when burning fossil fuel](<a href=“Answers - The Most Trusted Place for Answering Life's Questions”>What gas is released when burning fossil fuel? - Answers)</p>
<p>it is burning fossil fuels</p>
<p>Yeah the graphs were kinda hard… anyone remember any others?</p>
<p>ya the one with the corn oil, i said A. it was the only nutrient source for them</p>
<p>how much is 7w and 2 blank?</p>
<p>about a 700-750 according to PR</p>
<p>Did you guys put 25% for the percent of offspring from a male parent who had Polydactyly and a female who did not? (The question said that polydactyly was autosomal dominant).</p>
<p>i said 50%</p>
<p>i put 50% for it</p>
<p>ya its 50%</p>
<p>that was easy though…what about the ones with the graphhhsss lol ahhhh its drivign me crazy</p>
<p>I did the Punnet and almost put 50% but then I figured that the offspring had a 50% chance of being a boy or a girl and I though autosomal had something to do with sex-linked, so I magically multiplied 50% and 50% to get 25%. Thinking about it some more, I think my reasoning is flawed.</p>
<p>Phosphorous one was detergent. It’s part of the BC Science 10 curriculum we learned last year. The excess phosphorous would not cause a growth of multiple organisms because it’s actually quite toxic at concentrated levels.</p>
<p>Anyone who took E know the directional selection one? Was it the larger beaks?</p>
<p>Wait for the fungus problem (autotrophic, decompose, parasitic) question, can’t chemosynthesis be counted as autotrophic? Fungi might not be photosynthetic but those that are chemosynthetic would still count right?</p>
<p>What did you guys put for the 2nd question with the 18 oxygen and photosynthesis? It asked for a conclusion drawn specifically from experiment 1 which was:</p>
<p>6CO2 + 12H2(18 O) ------> C6H12O6 + H2O + 6(18 O)2</p>

<p>zhuzhupet–All fungi are heterotrophs. Chemosynthesis WOULD count, but fungi don’t do it.</p>
<p>The caterpillar and birds? What was the experiment an example of? I couldn’t decide what to put there.</p>
<p>Yay BC Science 10 curriculum!</p>

<p>I didn’t know anything about phosphorous cycle. PR and Barron only went through the water, nitrogen, oxygen cycle.</p>
