Hydrostatic & Osmotic Pressure

Hydrostatic & Osmotic Pressure

Water and small proteins leak out of capillaries at their arterial ends because hydrostatic pressure (exerted mainly by blood pressure pushing outward against the capillary walls) is greater than colloid osmotic pressure (a fluid-retaining force caused by large solutes in the blood). Most of the fluid returns at the venule end because blood pressure:

Juvenile Hormones

Juvenile Hormones

In certain insects, juvenile hormone suppresses metamorphosis from larva to adult. Instead, this hormone allows the young organism to grow in size while remaining in the immature larval stage. Eventually, the juvenile hormone decreases, causing metamorphosis to take place. If the corpora allata, the site of juvenile hormone production and release, is surgically removed an an early larval stage, what is expected to happen?

Of Medicine and Motivation

Sophia is the first of many students to be featured on MCAT Question of the Day. We feature students who have a passions for medicine, science, entrepreneurship, and journalism. Want to become a featured student? Shoot us an email and ask for more details.

Sophia Glisch

If you are readying yourself to write the MCAT, then it is almost certain that you have previously met with standardized assessments. Earlier in life, you will have – if you are studying in the United States or applying to a U.S. college – faced the SAT: a three-part, three-hour-and-forty-five-minute test that leaves most students, in between ragged breaths, boldly declaring that they, uh, don’t need to go to college. Among others, the LSAT, GMAT, or MAT may’ve also, if you’ve considered paths other than those involving medicine, woven their ways into your undergraduate experience. In brief, these examinations are realities of any student’s existence. They quickly become particularly prevalent, however, in the lives of those who choose to take the road that, if not less travelled by, always nevertheless seems just a little wild.

To continue with the conditionals, if you’ve met with standardized tests, then you probably know that they take time to prepare for. This is primarily because all these exams demand that you sharpen skills that you may not have to regularly use. The MCAT has you, for example, facing quantitative problems calculator-less. While you won’t exactly be mentally evaluating partial wave integrals on the test, being rusty on your trig is definitely not an excellent idea. With its medley of this form of computational work, passage-based reading, and a scored writing sample, the MCAT asks that you prove you’ve mastered several of these subject-specific specialized skills in a variety of ways – all in about five hours.

Intensive study well ahead of time is important precisely because you only have these five hours. You know that, on test day, you need to be working at optimal levels – quickly, accurately, and confidently. And while classmates may attempt to convince us that we can handle the material with “just a couple of practice tests”, and we really should skip the study session today and go out for a bit, I think we all experience that little nagging sensation informing us that we do, in fact, need to prepare.

Why is then that the vast majority of us, despite our knowing that preparation is integral to success, don’t manage to adhere to a study schedule? I suppose life takes over. A particularly heated debate with a family member, the end of a relationship, an unfortunate result on a difficult problem set, a momentary lack of confidence in one’s ability to even write the test. All of this and more can be grounds for an unplanned break of days or even weeks.

I am certain that all those reading this are presently wondering how you go about avoiding the aforementioned things. You don’t, as again, they are aspects of life that will most definitely greet all of us at some point in time. What you should do, however, is strive to remain motivated when these things occur. Every student has a different method of doing this, but I think that one of the best has been, particularly for me, reminding myself of why precisely I seek to write the MCAT. This may sound like a question that has an exceedingly obvious answer, but it is surprisingly important to (despite the fact that this may seem a waste of study time) occasionally remind yourself, step-by-step, of why it is that you’re sitting this time-consuming, rather demoralizing examination.

When the going gets tough, I run through my reasons. As fabricated as this may sound, I have always wanted to learn more. Early in life, I found within science a means of understanding more and more about the fascinating universe within which I live. This, then – wanting to learn more – is my primary reason for doing most of what I do, and the most general reason for my wanting to take the MCAT. From it stems the fact that, in order to further my ability to carry out the protein folding and medical biophysics research that I am presently involved in, I constantly need to enhance my knowledge of biology, chemistry, and physics. The MCAT requires that I check up on all my fundamentals, and successful completion of it, therefore, at least partially signals that my knowledge base and reasoning capabilities are adequate. Finally, though I am not presently contemplating a career in non-research medicine, writing the MCAT will assist me in presenting an interesting profile to universities that require successful applicants to showcase a broad range of capabilities. A good score will, too, permit me to apply to medical school should I later be interested in doing so.

Attempt to think of your reasons. If they seem obvious to you, all the better – work on simply ensuring that you don’t lose sight of them. If you find yourself in a patch of slightly nebulous thought where your priorities are concerned, write them down. Share them with friends. However you do so, ensure that you always keep in touch with your purpose. It is, after all, exceedingly difficult to truly do something if you don’t understand why you are doing it.


Bio: Sophia Glisch is a student currently residing in Toronto, Canada. Presently, though, she spends most of her days blogging, eating sushi, and working in a protein folding lab; for the past three months, she has also been preparing extensively for the MCAT.

Because Sophia is slightly younger than the average student writing the test, and because she has decided to make her MCAT journey an experiment in self-studying, some unusual challenges (and some useful insights) have come her way. She hopes that she can, through her writing, offer a perspective that will be somehow enriching, and somehow entertaining.

5 Most Popular MCAT Physics Questions

Top 5 MCAT Physics Questions

With over 140+ questions posted on MCAT Question of the Day so far, we’ve had many questions that have been more popular with our readers than others.

You’ve read our 5 Most Popular MCAT Biology Questions and MCAT Chemistry Questions, now it’s time to cover our most popular MCAT physics questions, starting from the very beginning.

Here are our 5 most popular MCAT Physics Questions since we started:

1. Missile Velocity: Our second physics question ever posted happens to be a nice conceptual problem. I find the picture to be pretty funny as well.

2. Force and Velocity: Use the force, Luke. A great problem to go back and review, also contains reference to Star Wars.

3. Low Stakes: Funny title + good problem to grab a calculator for = popular question.

4. Whistle While You Run: How much do you know about the Doppler effect? One of the few questions that the majority of students got wrong.

5. String Fixed At Both Ends: Great conceptual question that many students forget. Also, as a bass player, I particularly enjoyed the picture.

Well, that wraps up our list & our “5 Most Popular” series! As you could imagine, this list was quite hard to compile because there are no popular physics questions. I kid, I kid, but in the meantime, you should definitely follow MCAT Question of the Day on Twitter and on Facebook.

How To Study In Med School

MCAT QuestionsAllison Greco has kindly agreed to answer some of the top questions our community wants answered. Allison is a medical student in the class of 2013 and has a great passion for social media. You can follow her on twitter @grecoa3.

I’m a follower of your blog and twitter (@iPikl25), and I’ve been reading a few of your posts that I wanted to ask your advice on. You mentioned how you need frequent breaks to keep going. I’ll be starting medical school in the Fall and figuring out how to study is my biggest fear. So basically I wanted your advice on how you studied in med school. ~ Question from Sophia of Notes In My White Coat.

I have good news and bad news in regards to my answer for your question. The good news is that no, you don’t NEED to study the exact same way as everyone else and shouldn’t spend your time stressing over it. The bad news is that I definitely wouldn’t recommend being too lax when it comes to studying.

Bad news first: Medical school IS hard, and it’s probably not like anything you’ve ever done before. It’s probably the hardest you’ll ever work or study. It’s a lot easier to study TOO much in the beginning- it’s easier to start out with a strong grade in the event that you struggle later in the course on rather than struggle at the beginning and spend the rest of the course chasing a passing grade.

As a warning, you will probably NEVER feel prepared for a test. You’ll feel like you don’t know anything at all. All of this is normal, and it’s okay. Don’t let anyone make you inferior for that (chances are they feel the same way about something else). Most schools have pass-fail-honors grading systems, so if there is a class that just isn’t for you, its okay to save your sanity and get by with just a passing grade. With that said, you WILL need to take a the united states medical licensing exam (USMLE) sometime during or after your second year. The test encompasses everything you learn in those first two years (but please don’t stress about it yet!). It’s much easier to study for this test if you really, REALLY learned the material the first time over.

Finally, the good news: Don’t forget to take time for yourself. Most students took one day a week to do something fun. I liked to work out for about an hour a day, and unless there was some crazy circumstance or a huge exam. I also NEVER missed one of my prime-time TV shows. You’ll stress a lot in the beginning, but as time passes, you’ll become more comfortable with how much you need to study, and what your exam formats are like.
