<p>I've been reading the chemistry part of cliffs ap biology. I seem to have trouble understanding the chemistry part. Anybody can help me out here?</p>
<p>The chemistry part isn't that hard(it's somewhat long).</p>
<p>Look for the main points.</p>
<p>For instance it says that an atom with 7 electrons is more likely to bond than an atom with 8 electrons.</p>
<p>Also, it says a hyrogen bond, I believe, is ionic.</p>
<p>Ionic bonds have a harder time staying together.</p>
<p>Read the descriptions of the bonds, etc. and you'll be fine.</p>
<p>I got a 3 on the AP Bio test. and I'm going to take AP Chem.</p>
<p>I don't think enough pictures seem to be shown.</p>
<p>You should look for pictures online. I remembered a bunch of things from Chemistry, so that section wasn't a problem to me.</p>
<p>You should google search some pictures or maybe, wikipedia might have some pictures.</p>
<p>What exactly do you not understand?</p>
<p>Like less than 5% of the AP Bio test will have to do with chemistry. And yeah, just read up on wikipedia anything you don't understand of post here, but don't stress out about it.</p>
<p>i dont even think there were ne questions on chem on the test this yr. but let me know what you dont get and i should be able to explain i to you</p>
<p>That is true. There were no chem. questions, but there were questions about cells. Don't forget the basic things: chem, cells,...</p>
