<p>I have a couple questions regarding this list:</p>

<p><a href=“http://talk.collegeconfidential.com/14493881-post791.html[/url]”>http://talk.collegeconfidential.com/14493881-post791.html&lt;/a&gt;&lt;/p&gt;

<p>

</p>

<p>I’m pretty sure the third trohpic level would have 1% of the energy, right? </p>

<p>

</p>

<p>What three things? </p>

<p>

</p>

<p>What do you mean evolutionary order? Do you mean which organisms appeared first, second, third, and so on? </p>

<p>If so, the list is not right. The information below is a list of the times at which each organism first appeared on Earth. Ma means “million years ago.” The information below is sourced from Wikipedia. [Timeline</a> of evolutionary history of life - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Timeline_of_evolutionary_history_of_life]Timeline”>Timeline of the evolutionary history of life - Wikipedia)</p>

<p>b. Starfish: “modern starfish” appear 190 Ma
c. Shark: 363 Ma
d. Dinosaurs: earliest dinosaurs appear 225 Ma
e. Bird: a possible ancestor to the birds appears 155 Ma. Other relevant dates are 110 Ma and 60 Ma.
f. Whale: 55 Ma</p>

<p>54.yes it would have 1%
22.it was control secondary sex characteristics, do something to the anterior pituitary, and thicken the lining of the uterus (i’m not sure on this one)
11. ya what organism came first to last</p>

<p>Thank you. Then shouldn’t #11 be:</p>

<p>shark -> dino -> starfish -> bird -> whale?</p>

<p>Also, do you remember anything about the question involving the amino acid and the peptide bonds and the carboxyl group?</p>
