Get your day started with a new AAMC-style Question of the Day delivered to your inbox every day—except weekends, because you deserve a break!
Assuming the circulatory system in humans obeys Bernoulli's principle of fluid dynamics, which of these statements most accurately compares the blood pressure in a capillary of the neck to a capillary with an equal cross-sectional area in the right knee?
The pressure in the neck is greater than the pressure in the knee because of the increase in pressure head
The pressure in the neck is equal to the pressure in the knee because of the equal dynamic pressure according to the continuity equation
The pressure in the knee is greater than the pressure in the neck because of the increase in pressure head
An accurate comparsion cannot be given without knowledge of the fluid's density and viscosity.
If you are studying for the MCAT exam, you know how critical it is to practice on MCAT practice questions. Studying the sciences isn’t enough — 510+ scorers also know how to put that knowledge to good use. Each of our Questions of the Day is written by one of our elite 99th+ percentile instructors and comes with a thorough explanation. This is a great way to sharpen your MCAT skills in just a few minutes, and, regardless of whether you purchase MCAT prep with Blueprint MCAT, each Question of the Day is yours to keep. Take advantage of these practice problems and study these questions as if it were MCAT questions on the real MCAT exam. We’ll cover all 4 major MCAT science topics: Biology, General Chemistry, Organic Chemistry, and Physics — as well as questions on the behavioral sciences section. You will also get access to MCAT practice questions that have thorough explanations of the concepts with multiple choice answer choices, so if you miss a problem you’ll be able to understand why.
Here’s what you can expect when you sign-up for our MCAT Question of the Day:
MCAT Biology Question of the Day:
The Bio/Biochem section of the MCAT tests cellular and molecular biology, classical and molecular genetics, laboratory techniques, study design, and data-based and statistical reasoning.
The Psychological, Social, and Biological Foundations of Behavior section (also known as Psych/Soc) of the MCAT tests principles in sociology and psychology, including the biological, psychological, and sociocultural factors that influence the ways that individuals perceive, think about, and react to the world..
