Biology 2010 Prep

<p>the answer is 50%!!! ur all making it too complicated :)</p>

<p>For zones of the adrenal glands and their physiology remember the lower it gets, the sweeter it gets. The higher zone excretes salty things, the middle zone sugars, and the bottom sex hormones. Probably not applicable to AP Biology, but it made me laugh studying MCAT review cards!</p>

<p>I wished I lived on the West Coast. :(</p>

<p>I am very weird, I always go to bed that late and I’m not tired in the morning. I sometimes get tired at 4pm though…haha.
I’m just scared of changing my sleeping pattern, I did that 2 weeks ago and it made me so tired. Then I reverted back to my normal sleeping pattern and was a lot more awake.</p>

<p>Haha thx for the tip</p>

<p>i really hope that an frq is on photosynthesis, crassulacean acid metabolism plants, C4 plants, kranz anatomy, mesophyll cells, bundle-sheath cells, rubisco
or on taxonomy, porifera, cnidarians, platyhelminthes, rotifera, nematoda, annelida, arthropoda, mollusca, echinodermata, chordata, protostomes, deuterostomes, bilateral symmetry, radial symmetry
this is the good stuff, where knowing random vocabulary helps big time</p>

<p>My mom is about to disown me if I don’t go to sleep soon lol. I probably should - I got sick from standing out in the cold all day yesterday and today.</p>

<p>I feel like I need to cram something. ugh.</p>

<p>OKAY! Quick review on the five plant hormones!</p>

<p>–Auxins-- stimulates cell elongation and cell division! [Auxin==shortest plant hormone word, so think of reverse I’m SHORT so I MUST GROW LONGER AND BIGGER!]</p>

<p>–Cytokinins-- stimulate cell division too and the growth of lateral buds (wider)! [Cytokinins similar to cytokinesis, think of cell division and relate this to gibberellins–you know the other is tall growth so this is wide growth]</p>

<p>–Gibberellins-- promote stem elongation (longer) and breaks seed dormancy! [Gibb, reverse = big TALL]</p>

<p>–Abscissic acid-- CONTROLS bud dormancy, seed maturation and dormancy, and the opening/closing of stomata! (More acid = more closing and dormancy!) [People close up their bodies (sit-ups) to get more abs]</p>

<p>–Ethylene-- promotes fruit ripening and stimulates senescence and abscission in leaves and fruits! [I think of Esther as an old, ripened woman]</p>

<p>Am I correct in these?</p>

<p>alright bros. the time is before us to smite down the noobs. i’m going to bed now and will see you on the battlefield tomorrow at 8am</p>

<p>ooh ouch. Ok, refresher here: CAM plants are the cactus type things? Open stomata at night?
C3 is the “normal type” and C4 is the one that has an intermediary 4 carbon step when fixating carbon and has the bundle sheath things? or is it the otherway around?
What is kranz anatomy?
And i never really grasped the difference between clades and taxonomy or grades or whatever other types of classification there are.</p>

<p>i accept the challenge hydreptsi and good way to remember JFetrov</p>

<p>@JFetrov- sounds good to me :slight_smile:
Random fact: 2,4-dichlorophenoxyacteic is an auxin used as a herbicide and kills eudicots. haha i have to find a way to put that in an frq bc i read that section in the textbook, when i should have been reviewing stuff that will actually be on the test </p>

<p>Also, auxin overdose I think is more damaging than gibberelins overdoes (they both promote cell elongation tho)</p>

<p>haha hydreptsi so dramatic</p>

<p>JFetrov, I think you’re correct</p>

<p>@thehulk- huh? hydreptsi? </p>

<p>also abssisic acid controls stomata openings? I thought it had to do with K+ ions. or is it both?</p>

<p>@arwinevenstar, yes! Both can regulate stomata closing/opening.</p>

<p>Grrrr…I still have Spanish HW.</p>

<p>^It’s both.</p>

<p>Abssisic acid changes the osmotic potential of the guard cells, and that causes the K+ ion flow, which causes the change in turgid-ness (sorry, can’t think of a better word) and that causes the opening/closing of the stomata</p>

<p>OH MY GOD. i just did the cliffs practice test and got an mc raw score of 45, which translates to 27/60 on the mc :frowning: barely a 3. f f f f f f</p>

<p>^ Turgor.</p>

<p>All right. Circulatory systems. Heart has four chambers blah blah. Insects have open circulatory systems, they have hemolymph. Open systems pump blood into hemocoel, or the internal body cavity.</p>

<p>Arteries are red, veins blue. Pulmonary artery brings blood from heart to lungs. Vena cava / deoxygenated. Think of cave as empty. Blah blah.</p>

<p>Do we have to know all of the phyla? I’m not really up to learning about how a seashell is different than a whale.</p>
