<p>diiamondss, it was all three</p>

<p>and I looked up glucocorticoid, it’s steroid based hormone so it’s not a protein.
I think I read the question wrong 0_0</p>

<p>^Wait did they ask a specific question about whether it was protein or steroid?</p>

<p>It was part of the I, II, III
The kinds of question that I personally detest :P</p>

<p>Wait so did TAT regulate transcription or translation?</p>

<p>I think I put translation.</p>

<p>Wait, it asked about what TAT was, not glucocorticoid!</p>

<p>for the angionsperms/gymnosperms it was asking what they had in common…seeds</p>

<p><em>sigh</em> If only one of my other tests went as well as this one.</p>

<p>So i know we’ve already discussed the huntingtons disease problem, but was there a genetics question where the answer was 0%?</p>

<p>Yeah, I think I remember something about the flowers. The problem was asking whether it would be possible to have a phenotype with white flowers, but I think all of the offspring ended up being pink. so it was 0%</p>

<p>Yes, I distinctly remember a question where the answer was 0%.
Miriel is right about the question specifics.</p>

<p>:-D :smiley: :-D. not that that one question alone will help my score… :-P</p>

<p>No one ended up answering this question in older posts to my knowledge, so I’ll post it again, because I’m curious:</p>

<p>Where are the starch digesting enzymes?</p>

<p>I put small intestine, because thats where starch digestion occurs, and I didn’t put mouth and small intestine, because the mouth has enzymes that simply break down starch, not digest it.</p>

<p>Responses, anyone?</p>

<p>Yeah, it’s mouth and small intestine; E.</p>

<p>Mouth does have the enzyme for breaking down starch in the saliva.</p>

<p>CliffsAP has failed me haha.</p>

<p>

</p>

<p>This I KNOW is untrue. There is no such thing as carriers for Huntington’s (hello? it’s autosmal dominant).</p>

<p>I pretty much back up everything l4dygaga says.</p>

<p>^okay I think they just meant heterozygous…point is still made. Also, can someone please remind of the third plant lab?</p>

<p>I think collegeboard wasn’t expecting test-takers to average the two percentages for the answer. (75%, 50, & 0 are usually answer choices for those genetic questions)</p>

<p>I feel that they had the intent of making the test-taker do just a simple mono-cross to get the answer.</p>

<p>Ohh… yeah heterozygous it does make sense. It’s just a simple Punnet Square.
But the other guy’s argument was that you don’t know whether the dad was homozygous or heterozygous, so this doesn’t apply so much.
<em>Sigh</em> Let’s just suspend argument on the Huntington’s one until we get our scores back.</p>

<p>Third plant lab was two 6-inch plants growing, one in a box and one outside. The one outside grew straight up towards the light source, while the one in the box grew to the side that received light, thus displaying phototropism.</p>
