<p>i always thought bio was hella easy until now...anywayz, if there's anyone else on the forum who's taking Oct bio please join this thread, i hate cramming by myself.</p>
<p>i guess i'll start: what happens during interphase II ?</p>
<p>synapse and crossing over</p>
<p>What are the roles of the cerebrum, medulla oblangata, hypothalamus, cerebrum, and the brainstem?</p>
<p>cerebellum:balance, muscle cooperation
medulla: heart rate, breathing, etc.
hypothalamus:thirst, hunger
cerebral cortex:voluntary movements
brainstem:route for communication between brain, spine, wutnot</p>
<p>what hormones does each gland of the human body secret and what does each one do? (trying to organize this..)</p>
<p>wth synapse and crossing over occur in Prophase I</p>
<p>crap my bad...i was thinking prophase 1 for some reason.</p>
<p>acutally i don't think interphase II exists at all...my mistake sorry lol</p>
<p>yea, i'm totally gonna ace the test.</p>
<p>I'm definitely in the same boat...I am just now starting to study 6 days before the test! However, I'm in IB Bio II (which is...pretty intense, to say the least) and so I know a lot about the molecular side of biology. I have all the steps to glycolysis (as in glucose>glucose-6-phosphate> ....phosphoenolpyruvate>pyruvate) memorized and also the steps of the Krebs cycle and photosynthesis but I've forgotten everything about any part of biology that ISN'T molecular. I know that Barron's is supposedly the hardest prep book and if you memorize it you'll be fine but my bookstore was out of Barron's so I just got the Sparknotes book. What book are ya'll using?</p>
<p>kaplan's review is good</p>
<p>Ok for the hormones. </p>
<p>Anterior Pitutary Gland:
FSH (develops follices)
LH (causes ovulation)
ACTH (stimulates Adrenal glands)
TSH (stimulates thyroid glands)</p>
<p>Prolactin (makes milk after birth)
I(gnore)
Growth Hormone (growth)</p>
<p>Posterior Pituary Gland:
Oxctocin (sp?) (ejection of breast milk/ uterine contraction)
Vasopressin (Anitduiretic) (salt reabsorption)</p>
<p>Thyroid:
Thyroxine (accelerator of body)
Calcitonin (calcium from blood to make bones)</p>
<p>Parathyroid:
Parathyroid Secretion (lol not exact but close) (breaks down bone to create calcium in blood)</p>
<p>Adrenal Medulla:
Epinephrine (speeds up system)
Norepinephrine (slows down system)</p>
<p>Adrenal Cortex:
Glucocorticodes (creates glucose for use immediately)
Mineralcorticodes (reabsorption of water)
Sex Steroids (No Idea....stupid princeton review)</p>
<p>Pancreas:
Insulin (store glucose and take it out of blood)
Gluacagon (break glycogen and add glucose to blood)</p>
<p>Gonads:
Testoserone (male sex charateristics)
Estrogen (forget official names) (female sex characteristics)</p>
<p>Next Question:
Outline Photosynthesis</p>
<p>college info, i admire you....i would love my brain if it was as smart as yours....do yo uahve any idea of how i can memorize all that?</p>
<p>OK so I just took my first diagnostic and did HORRIBLY. That was before any studying though, so my next practice test should be better. </p>
<p>Alright, has anybody come across a question in which it is a chart-type-thing that lists the number of differences in amino acids for different kinds of animals? For example, if a human and a gorilla have 3 differences but then a human and a lemur have 39 differences, it's showing that the human and gorilla have a more recent common ancestor than the human and the lemur. Anyway, there were questions about this type of thing and while it seems really easy I simply CANNOT UNDERSTAND IT. There was this weird branching-off diagram and the question asked you to pick which animal would be put in which spot and even after reading the explanation about 500 times I still don't get it.</p>
<p>Lol, I've been studying since July and still am getting only a 690 on practice tests. So it turns out I'm actually dumb. </p>
<p>j07 yeah I think I've seen that question. Is it the one where they ask you to say where mammals with claws and mammals with fingers seperate?</p>
<p>No, it was something about amino acids in beta-hemoglobin in humans, gorillas, chimpanzees, etc. etc. But yeah, it was sort of along those lines of splitting off. I don't know, I don't think I'm going to understand it before the test so whatever. </p>
<p>What is considered a 'good' score on Bio? Is it like Math II where a bunch of people make 800s? In my prep book it says that you can only miss one and still get an 800...does anybody know if that is true? Or could you miss 2?</p>
<p>I think 2-4 constitutes for a 800. Yea, since the less amino acids differences there are that means that the closer the coding for a protein has to be. So the closer the coding means the closer the mRNA and the closer the mRNA than the closer the DNA. If there are few differences in DNA it means divergent evolution has occured like the gorrilas and humans that have only a 1 aa difference while gibbons have like 8 aa differences. So humans diverged from gorrialas after they diverged from gibbons meaning we are closer to gorrilas. Hope that cleared it up a little.</p>
<p>Well I'll add my name, Which book are you using j07? I might be using it too, so I'll be able to see the question you're talking of.</p>
<p>I don't really know about the 'good' score part. I'd think that it would be different from Math II in that since an 800 is so hard to get, (I think it varies from 1 to 3 mistakes depending upon the type you take), so a 750+ would be good, I suppose. Depends upon the college.</p>
<p>i got 610 on kalplan diagnostic test, 680 and 720 on 2 sparknotes practise tests, what should i expect on the real thing?</p>
<p>i think anything above 700 would be decent...750+ will def. be good anywhere. bio has a pretty harsh curve.</p>
<p>and this is a study thread so ppl lets keep the questions coming...:P</p>
<p>which hormone (yea i hate them too) does corpus luteum produce? estrogen or progesterone? and what does it do? (missed this on the prep test)</p>
<p>and do you have to know the ear and eye structures/diagrams, those of you who have taken the real test? it's on kaplan but not sparknotes :/</p>
<p>I'm using Sparknotes and have so far gotten like a 640 and a 690 on my first two tests. </p>
<p>I'm not sure if you have to know the ear/eye diagrams, but they are pretty easy to learn. I think that if you just know the general functions of the retina, the lens, the pupil, etc. and then the difference between rods and cones you should be OK for the eye. </p>
<p>I don't know if I should take Bio E or Bio M. I took both parts of one practice test by mistake and got the exact same number wrong on both. I don't really find one easier than the other...which one should I do?</p>
<p>Corpus Leutum give out progesterone.</p>
<p>Some one want to tell me the parts of the eye and their funtion I dont know that and I don't have Kaplan.</p>
<p>cornea-bends and focuses light rays</p>
<p>pupil-controlled by iris, which responds to intensity of light, and constrict/dilute pupil</p>
<p>retina-transduce light into action potentials (imaged is upside down)</p>
<p>cerebral cortex-interprets image</p>
<p>cones/rods:photoreceptor cells on retina.
cones respond to color
rods respond to black/white, important for night vision</p>
<p>what are the stages an ovulated egg go thru?</p>
