BLUEPRINT MCAT® BLOG
At Blueprint, we believe in educating first. Our MCAT blog was created to reflect this value. Our articles are written by the same MCAT experts who write our MCAT books, MCAT practice exams, and our MCAT course materials. We also partner with guest contributors regularly, both professionals and industry experts, to make sure that you are getting information that is not only relevant, but accurate.
Learn from the best with this free MCAT resource, updated with new articles regularly. If you need to know about a specific MCAT subject, changes being made to the MCAT exam, and general information about the MCAT, our blog is the perfect place for you.
MCAT Chemistry Practice Question – Amines
Hexanamide is primarily used in organic synthesis as an intermediate in the production of pharmaceuticals and agrochemicals. It is also sometimes used as a solvent. If hexanamide is treated with ethanol, what would be the expected products? A. Hexanamide and…
MCAT Chemistry Question — Electrons
Green fluorescent protein (GFP), is commonly used in imaging studies due to its fluorescent properties. It absorbs ultraviolet light and emits green light. Which of the following best describes what happens to the excitable electrons in GFP immediately after exposure…
MCAT Biology Question — Affective State and Memory
In a worksite accident, a man is shot with the nail gun several times in the head. X-ray imaging shows penetration of the nails into structures of the brain. Miraculously, the man survives but experiences some issues remembering new information…
MCAT Physics Question — New Force
Two charges, Q1 and Q2, experience an attractive force between them, F1. If the distance between the charges is tripled, the sign of Q2 is changed, and the magnitude of the charge on Q1 increases by a factor of nine,…
MCAT Chemistry Question — Weak Base
Fluoride is a very weak base that is added to drinking water at a concentration of 0.7 mg This concentration strengthens the enamel of the tooth surface to prevent the formation of cavities. The pKb of this base would likely…
MCAT Organic Question — Isobutyric Acid
A researcher synthesizes isobutyric acid through the oxidation of isobutyl alcohol with potassium permanganate. The reaction was completed in a diethyl either solvent. In order to extract isobutyric acid from the solvent, the researcher should wash the solution with: a)…
MCAT Biology Question — Sweating
Hypohidrotic ectodermal dysplasia is a genetic disorder characterized by a decrease in the number of sweat glands in the skin. Individuals with this condition would have difficulty with which of the following processes? A. body temperature regulation B. plasma osmolarity…
MCAT Organic Question — Alkyl Halide
A synthetic chemist must synthesize an alkyl halide using an alcohol and HCl. While she does not have many available solvents, she concludes that with the right reaction conditions, the alcohol can serve as both the substrate and the solvent.…
MCAT Physics Question — Sound Travel
A researcher is designing an apparatus to detect sound waves transmitted through the ground. Part of the design involves a tube that connects the sensory apparatus to a detector. What should the tube be filled with to ensure the most…
