<p>Both of your answers are wrong. For the half life question, it said how many days must it take to maintain a conc. of 10 or higher. If the halflife is 20 days, then in 20 days 10 will be left and it must be reaplied so that it maintains the 10.</p>

<p>For the other question, it was about scientist 2 not 1… Meaning there were a bunch of random mutations thoughout from a single unmutated cell. Choices C and D both started with mutated cells so they were wrong by default i think. The questions was for scientist 2 not 1 which is why B was right.</p>

<p>answers

  1. the branch one was b
  2. 20 days
  3. x1 + x2
  4. boyancy= decrease
  5. cell respiration
  6. allelles
  7. 1993/ 1997 respectively
  8. Risistor 2 had more heat because higher resistance
  9. Sector 6 for biking question.
  10. average was 165 167 170 173 175
  11. As D increased the t decreased
  12. Order was A, B, C
  13. Liquid C because it had a higher viscocity.
  14. Liquid L would be over 194 sec.
  15. Scientist 2 believed the mutation can occur before exposure, scientist 1 did not believe that.
  16. Scienits 2, 3 had the same belief.
  17. 10 and 1000 would cause the most resistance
  18. Concentration of that one substance doesnt necesarilly increase or decrease with more of the deposit</p>

<p>Anyone remember all 7 sections. I remember the bowl, the biker, the river, the mutations, the resistors… what were the other 2?</p>

43

<p>olleger - do you remember what the question was for 18?</p>

44

<p>It was in the deposit one. It was like if the ammount of deposit increases will the ammount of this thing increase? Idk but it was no because there were many pts. at one x value.</p>

45

<p>I think I know which one you’re talking about, thanks!</p>

<p>I can’t remember the other 2 at the moment, but I’ll keep racking my brains…</p>

46

<ol>
<li>average was 165 167 170 173 175</li>
</ol>

<p>how? It said the average was 160 or something,asking for what the individual ones were. Your values are all higher.</p>

47

<p>I got forty as well…
ah whatever D:</p>

48

<p>Mango Man - either the average was 170, or the answer was 155 157 160 163 165. Regardless, that pattern stays the same.</p>

<p>jelecrois - I’m almost positive it was 20. At least I hope. It’s only one, right? :/</p>

49

<p>Another section was decomposition of N205</p>

50

<p>haha what was that passage again? Usually I remember everything on tests but i forgot that</p>

51

<p>yeah i rem the passage, was that the 2nd last passage?</p>

52

<p>truee trueee.
how bad do you think the curve is gonna be?</p>

53

<p>i put 20 days. i rushed at the end and it was a complete guess, hope im right! :D</p>

54

<p>Anyone remember anything from the decomposition of N205 experiment?</p>

55

<p>uhh yeah i remember that question… uhh was it like “where will no2 be when the n2o5 is fully decomposed?” wasn’t it like .4 or something like that?</p>

56

<p>@killer</p>

<p>yea I think it’s something like that. Do you remember the other answer choices?</p>

<p>Also, what was the question for the answer “cellular respiration”?</p>

57

<p>we have a consolidated list on page 3 I think it is ; )</p>

58

<p>ok so adding to olleger’s consolidated list:</p>

<ol>
<li>the branch one was b</li>
<li>20 days</li>
<li>x1 + x2</li>
<li>boyancy= decrease</li>
<li>cell respiration</li>
<li>allelles</li>
<li>1993/ 1997 respectively</li>
<li>Risistor 2 had more heat because higher resistance</li>
<li>Sector 6 for biking question.</li>
<li>average was 165 167 170 173 175</li>
