<p>Question pertaining to Animal Form and Function:</p>
<p>[ul] [li] Gas diffusion in human lungs occurs across membranes of [/li][list]<a href=“A”></a> Alveoli
<a href=“B”></a> Bronchi
<a href=“C”></a> The Diaphragm
<a href=“D”></a> The Larynx
<a href=“E”>*</a> Spiracles [/ul][/list]</p>
<p>A - Alveoli</p>
<p>Yes it is definitely A.</p>
<p>We just started Animals; our first chapter is due Monday so I can’t answer animal structure questions yet.</p>
<p>can someone help me with the reason why fungi are more closely related to animals than to plants, i have to write a paper on this.</p>
<p>and to answer mifune’s question (D) reverse transriptase</p>
<p>the one about hiv I ment</p>
<p>Does everyone seriously remember everything?? Or are you guys looking up the answers? I can’t even answer half the questions…</p>
<p>^ seriously right? hahahah if i review everything will come back for sure. it’s kind of sad I don’t remember all these tiny details - i will be Pre med too haha.</p>
<p>

<p>Cladistically-speaking, I would build off the idea that fungi actually have a more recent common ancestor with animals than they do with plants. Although fungi may superficially appear to be categorically similar to plants, there have many more molecular associations with animals than with plants. To reference a genuine and very interesting factoid that I read in the past, the mushrooms in your dinner salad are more genetically similar to you than the lettuce, tomatoes, and other plant material.</p>
<p>As for a few basic similarities, both animals and plants utilize the molecule chitin for structural integrity, while plants use cellulose. Moreover, fungi and animals are heterotrophic, rather than autotrophic, unlike plants. That is, they must consume outside sources for nourishment.</p>
<p>But that is a very interesting topic! It is very fascinating to note that exterior and apparent similarities are not always reflective of actual ontogeny.</p>
<p>
</p>
<p>Yep, nice job.</p>
<p>
</p>
<p>Well, that is what will be required of us all on the AP exam. Thankfully, it is only necessary to know the correct response approximately two-thirds of the time. As for remembering concepts, I think I have a decent grasp on most of the AP material.</p>
<p>Mifune, do you think you’ll get a 5?</p>
<p>I hope so.</p>
<p>What does everyone think their score will be?</p>
<p>Me personally, I think a high 4 or a low 5.</p>
<p>
</p>
<p>With a username like Adenine, I think you certainly have the interest in the subject to receive a 5.</p>
<p>C5h5n5. ?</p>
<p>Adenine (the molecule, not your Internet identity) has a molecular formula of C5H5N5.</p>
<p>Oh 
you know more about it than I do.</p>
<p>Anyone know which is the best review book for the exam? Cliffs or PR?</p>
