<p>what is the difference between archaea and bacteria? i think thats a question</p>

162

<p>^the question was why a certain type was similar to another… and I skipped that one.</p>

163

<p>oh lol anyone happen to know the answer for that one? and anyone have any input on the rat one? thanks</p>

<p>i think im up to -7 ■■■</p>

164

<p>Same, -8…i also put lungs/gills, i put rat & squirell because their both rodents?</p>

<p>for the acrhea bacteria, the question i think was why are they more related to eukaryotes than bacteria…i forgot the answer choices… mabey something about amino acid sequences?
i think thats right

165

<p>I like how we are completely ignoring E section lol.</p>

166

<p>i forgot the choices but i think i got it wrong</p>

<p>-8 sigh</p>

167

<p>oh yes yes I remember! and I put amino acid sequences for that one as well because I remember reading how the new system of classification classifies by amino acid sequences because of it’s accuracy.</p>

168

<p>the archaea and bacteria one was because archaea have introns, just like animals</p>

<p>the amino acid sequences was for the cytochrome protein question, not this one</p>

169

<p>how much is 4 wrong and 1 omit</p>

170

<p>oh and what was the answer to teh question about oxidation-reduction reaction?</p>

<p>was it that one loses an electron and one gains?</p>

<p>or was it the formation of ATP D:</p>

171

<p>oxidation reduction: one loses electron one gains</p>

172

<p>^I second that waterbottle.</p>

<p>btw what was the curve for the m section last year?</p>

173

<p>@babybutt according to sparknotes, thats a 760</p>

174

<p>ah curve plz curve D:
lol i dont understand
how this “curve” works? anyone care to explain? :/</p>

175

<p>What wanderyonder? I dont remeber introns att all, mabey amino acid sequence was choices for both, and the answers for both?</p>

<p>and wikipedia says this: Post-transcriptional modification is simpler than in eukaryotes, since most archaean genes lack introns, although there are many introns in their transfer RNA and ribosomal RNA genes,[100] and introns may occur in a few protein-encoding genes.[</p>

176

<p>^jj I put amino acid for both too, it made more sense imo.</p>

<p>ps: wiki is not the most omnipotent resource ^.-</p>

177

<p>anyone got any questions? im really starting to get worried lol -8</p>

<p>whats the score if i get 8 wrong? :O</p>

178

<p>What did you guys get for the bag and the sugar and diffusion of water one -10</p>

179

<p>what happens if a question is ambiguous
for example that question wit the
“Which pair is the most closely related” or w/e
because evolutionarily, chicken and lizard are the closest
on the other hand, relationship symbioticaly, the human and e.coli would be close</p>

180

<p>^baby, well that would be, theoretically what the curve is for… to answer such discreptancies.</p>

<p>I answered e coli…</p>
