<p>@pizzacrayon it was the one that looked like a disruptive selection graph, because half the population would be vibrant and half would be dull but few if any would be in between</p>
<p>that’s what i had too! ^</p>
<p>Also what did the blue-green algae not have? Was it chlorophyll?</p>
<p>i put chlorophyll but wasn’t 100% sure…i thought i remembered learning that in bio though so hopefully we’re right!</p>
<p>Blue-green algae are also known as Cyanobacteria in Domian Bacteria. This was a huge one in the Princeton Review study book. They do have chlorophyll to photosynthesize. </p>
<p>Cyanobacteria don’t have Mitochondria because they are essentially a chloroplast i.e. Endosymbiont Theory <a href=“http://upload.wikimedia.org/wikipedia/commons/thumb/9/92/Chloroplast-cyanobacterium_comparison.svg/2000px-Chloroplast-cyanobacterium_comparison.svg.png”>http://upload.wikimedia.org/wikipedia/commons/thumb/9/92/Chloroplast-cyanobacterium_comparison.svg/2000px-Chloroplast-cyanobacterium_comparison.svg.png</a></p>
<p>haha darn…thanks for the correction though!</p>
<p>Yup I did it as mitochondria because I thought if theyre bacteria they have no double-membrane structures. </p>
<p>Anyone who took M: what did you say for which ions were pumped into the cell? I thought it would be calcium, potassium, and (something else, I forgot. Whoops.) but I didn’t know if the question was asking which are pumped in to maintain the charge difference, or if the question was referring to what happens when a nerve impulse passes…</p>
<p>Ugh if I got 750 how many would I have missed?</p>
<p>So depressing that act scores were also released today</p>
<p>@nishaus That’s amazing! Congratulations :)</p>
<p>I got a 770 on Bio, and a 790 on Latin. Bio didn’t go up a lot since last time, but I’m ecstatic about Latin : )</p>
@Nariman that’s so sweet thanks
