Well, if you sever the optic nerve then the person would become blind. In order to sever it, though, you would have to make some sort of incision, probably on the eye, in order to actually reach back to the optic nerve and cut it. Though, maybe it would just snap if someone tried to rip a person’s eye out. I don’t know for sure. If it were to snap without having to destroy the eye then removing the muscles would definitely cause bleeding since they are vessel-rich. Otherwise they wouldn’t be getting the nutrients they need to function.
As for the amount of blood I’m not entirely sure, but from my experience and knowledge, bleeding from lesions around (or inside, really) the head would be a pretty good amount because of the pressure inside the head. Maybe a person could bleed out if they don’t try to get to the ER, but I’m not sure about how efficient blood clotting is for an injury like that. As for the pain it would likely be excruciating because that’s a very sensitive area. (Fun fact, the brain doesn’t have pain receptors.) The person could definitely survive if he/she gets medical attention, but of course, that person would remain blind since we don’t yet have to technology to repair such a thing.
Well, given the perceived desperation of your ask… I wonder, why did you wait until now to seek help with this? Though I suppose it’s too late for that now. At least learn that lesson from, this, though. Because in college you can’t afford to do that.
If you thought your professor was easy, then it is very likely that s/he did not push your class hard enough. That is usually the marker for whether or not students will do well on the AP. It’s the classes who collectively struggle to get good grades that tend to get 5s. A less-than-ideal grade in AP Bio would be worth not taking it over again in college, to me. So if you feel like s/he didn’t push you, it’s unlikely you’ll reach a 5 without having done extensive work on your own time, if that’s what you’re aiming for. Especially if you’re this frantic to study for it this weekend while blaming this on your teacher. Blaming it on your teacher isn’t going to make you perform better. People can and will see that as an excuse. Just a reality check.
All you can do is do practice questions at this point. You might have some time to do review, but you’re going to need to go ham on practice problems. That’s it. There’s no magic formula to do well on the AP other than hard, consist work throughout the year. If you haven’t done that, there’s no guarantee you’re going to do well. I got easy As in my AP bio class in high school, but I also studied for it every single day. And I nearly got that 5. So while your teacher can set you up for success (or not—which is not the same as setting you up for failure, btw) most of it is up to you and how much you studied over the course of the year.
Cramming will get you nowhere for the AP or in college. You can’t cram and get an A on a cumulative college final. So prepare for that now. (Or after your AP, I suppose.)
I’ve pretty much already answered this question already.
Well, it sounds like your high school works a bit differently than mine did. I had to take sophomore biology and physics (I took AP) as a prereq for AP Bio and AP Chem. At least at my school, regular biology was a really easy A, but I think it’s worth getting the exposure to it before the AP, because the AP is considerably difficult.
In my experience, I got a pretty easy A in my AP Bio class. However, that made the AP much harder. One of my friends in college told me he did terribly in his AP Bio class, but nearly everyone in his class got a 5 on the AP as a result.
So from what it sounds like, your high school AP Bio class must prepare you very well for the AP exam. (Obviously I can’t know for sure, but that’s the impression I get.) And really, I think the AP credit is pretty important so you can have more electives or take a lighter course load in college if you want. But having harder AP classes also prepares you better for college.
So from my perspective, even if you are a straight A student, I think it might be in your best interest to take regular bio, ace it, and then take AP Bio after. Every additional exposure to material will be helpful. And I assume you don’t wish to blemish your GPA by taking it cold without any sort of intro to the course.
I can’t know how helpful your guidance counselors are at your school, but they, or perhaps your science teachers, may be able to give you better guidance.
Homologous refers to chromosomes that contain the same genes at corresponding loci. You have two, one for a paternal allele and another for a maternal allele.
My AP Bio final is the next two days, so I will be studying a ton… Probably meaning a lot of stuff posted on here soonish. I’ve been making handwritten study sheets for A&P which I think is enourmously helpful to making sure I know something.
Drawing or writing out something by hand is the best way to learn. That’s why I keep a sketchbook of anatomy and physiology and I love my A&P coloring book. (Definitely invest in one if you’re going into medicine!!)
I will finish off my study sheets after school is over, because after my AP Bio final I have a Gov project to finish and some Physics labs to do. Sorry if that is kinda crappy for anyone else, but I’m only one person and I’m not perfect! (Plus, making your own sheets is SOOO helpful.)
The Kidney and Nephron
I couldn’t find a “urinary/excretory system” video from my go-to bozemanbiology, but I found this… And it is so clear and concise. I may start going back through some things with KhanAcademy to see if it clarifies anything Mr. Anderson (of bozemanbiology) reviewed with me. ;)

Ones that are actually scientifically accurate yet still pretty decent musically. Highly recommended.
I’m sure you guys all have finals. Don’t unfollow just yet. My guidance counselor always says, "It’s not done until it’s done." Meaning studying shouldn’t necessarily stop until school is over. (Or for my case, when I graduate.) Learning is a life-long process, after all! As Gandhi would suggest in my favorite quote of his, "Live as if you’ll die tomorrow; learn as if you’ll live forever."
Haha, I actually wrote a brief post about it on my main blog here. (You read my mind!) Since I can’t talk specifics on the content of the test, I’ll stick to my thoughts on the formatting. ;)
But honestly, I thought it was difficult, in the sense that it was a challenge. I’m actually really glad it wasn’t too easy, because I think I would’ve been too confident with myself or over-thought the answers. Especially with the multiple choice. I actually managed to get through the 100 multiple choice questions of my first pass in about 30 minutes. And I seriously wasn’t even rushing; I was extremely focused. I felt like during the other two passes I was more confident in my answers. I somehow made a lot of time for myself during the multiple choice… I don’t know how, but I suppose I consider myself lucky. (Thank you, God?! Haha.)
As for the free response… I think that was the easiest part to understand out of the whole test, the only fight I had with time was getting all that I wanted to say down on the page in time. I didn’t even write any “fluffy stuff”. I made it all very concise, yet still detailed. Again, I’m actually amazed that I did it so efficiently, but I suppose that’s due to all the hard work I’ve been doing to prepare myself. (I even managed to cross-over a lot of topics with my examples, further proving how much knowledge I’ve acquired from my immense studying.)
But let me tell you… If you thought it was difficult, don’t feel discouraged, because even someone like me, who has literally been spending all her free time studying for this test, found it to be difficult. I think the game changer here, though, is how much interest and focus you can put into the test. I love biology with all my heart and, yes, I’m crazy enough to study it for fun. I truly think that makes all the difference; being passionate about something can make you do amazing things. :)
I hope it went well for you guys!! Good luck! If you don’t get a score you want, just assure yourself that you did your best and make a promise to yourself that you’ll just keep improving. :)
Just some AP Bio humor my friends posted on Facebook. Lol. Even a super-nerd like me thinks it’s funny, so it must be hilarious if even I wouldn’t get offended by it, hahha! :P
