<p>Well, I feel pretty prepared. I feel a solid four, hoping for a five. Today I will be rereading parts of my text book, especially on the Cytoskeleton, Invertebrates/Vertebrates, and Plants. Really hoping for a five.</p>
<p>Probably he only thing you need to know about the cytoskeleton is that it offers support and it’s composed of microfibrils, microtubules, etc. It’s going to be even less specific than other organelles. I’m doubting there would even be a question about it.</p>
<p>In regards to the skeletal system, I’d say the most important thing to be able to do is differentiate between the nortochord (primitive spinal column, especially for basic vertebrates) and the neural tube (gives rise to most organs during organogensis)</p>
<p>@StudiousMaximus
There’s a released 2004 exam???</p>
<p>@RandomGuy: I don’t know if it’s released, but my bio teacher gave it to us for practice. Does anyone have the answers? It’s pretty useless to me without them.</p>
<p>Just looked at the FRQ’s from last year. I would’ve aced those first three. Unfortunately, we probably won’t be seeing those this year. Argh…</p>
<p>so im pretty confused on what law linked genes violate… some people are saying it violates the law of independent assortment (migration of homologues in one homologous pair does not influence the migration of a homologue in another pair). it doesnt seem right to me because it sounds more like it violates the law of segregation (segregation of alleles/chromosomes to opposite poles) . </p>
<p>Can someone please explain if im wrong ): ?</p>
<p>also, does nondisjunction violate the law of segregation too?</p>
<p>ugh i had apush and now im cramming for bio. can i have tips on what’s the most integral to study?</p>
<p>@calcalcalvin</p>
<p>i would think it violates independent assortment as that’s the law that says different alleles are not influenced by each other in how they separate, and that they can separate from each other. linked genes are usually always in the same gamete and thus do not usually separate from each other, unless they’re very far apart. </p>
<p>but then again, i could be wrong…</p>
<p>anyone have a good list of all hormones (specifically female ones) like FSH, LSH, Estrogen, progesterone, etc…I really get confused as to the functions</p>
<p>ahh i’m taking the ap bio exam in about 5 hours!!! doing last minute review right now…</p>
<p>@ttam i think bozeman has a god video on that. otherwise idk I’d check sparknotes maybe.</p>
<p>Time to start reading Cliffs! Ah… I think I’m going to be sick. -_-</p>
<p>everyone is in their rooms today studying for ap bio instead of spending time with their moms… LOLOLOL</p>
<p>Female hormones</p>
<p>PRL (prolactin) - production of milk in breasts
FSH (follicle stimulating) - develops egg in a follicle before it is released
LH (lutenizing hormone) - releases egg halfway through the menstrual cycle</p>
<p>Other hormones</p>
<p>GH (growth hormone) - normal growth regulation
Islet cells - produces insulin that prevents diabetes
Proinsulin - inactive form of insulin
Glucagon - opposite of insulin, increases blood glucose
Insulin - decreases blood glucose
Glucocorticoids - increases blood glucose
Mineralcorticoids - increases reabsorption of sodium and excretion of potassium
Calcitonin - lowers blood calcium
Adrenaline & nonadrenaline - increases blood glucose, fight or flight response
PTH (parathyroid hormone) - increases blood calcium</p>
<p>Am I the only one that literally can’t focus right now or is that simply by virtue of the fact that my teacher has had us preparing in class for three weeks?</p>
<p>I feel similarly Matugi; I just want to get it over with already! And, if it helps, I remember the order of the female reproductive hormones with this acronym:
FSH
Estrogen
Lutinizing Hormone
Progesterone</p>
<p>Should we use pencils or pens for Free-Response Questions?</p>
<p>you should use pen</p>
<p>I don’t feel all that stressed… until I suddenly come across a question I have no idea about in an MC or FRQ.</p>
