Which state of matter has a fixed volume, is incompressible, and takes up the shape of the container?
Liquid
A man walks 30 m east and then 40 m north. What is the difference between his traveled distance and his displacement?
This effect describes when individuals do not intervene to help victims when others are present
Bystander effect
Glucose, NADP+, and ADP are all products of light-independent reactions for which process?
Photosynthesis
What is the highest-energy orbital of elements with valence electrons in the n = 3 shell?
d-orbital
A scientist looks through a microscope with two thin lenses with m1 = 10 and m2 = 40. What is the overall magnification of this microscope?
The overall magnification of a system of multiple lenses is simply the product of each lens’s magnification. In this case, that is 10 × 40 = 400.
What type of learning occurs when a previously neutral stimulus becomes associated with an unconditioned stimulus and eventually produces a response?
Classical conditioning
What is the average score of all test-takers on the MCAT and DAT?
DAT: 400/600
An impairment to which membrane-bound organelle would most likely result in a patient having an accumulation of cellular waste?
Lysosome
At standard temperature and pressure, a chemical process is at equilibrium. What is the free energy of reaction (ΔG) for this process?
ΔG=0
This term describes a ratio of the useful work performed by a system compared to the work performed on the system.
Efficiency
What term describes the tendency for people to change their behavior or opinions to match those of a group?
conformity
On average, how long does it take to receive a score back after taking your MCAT/DAT?
3-4 Weeks
Which enzyme is responsible for unwinding the DNA double helix during DNA replication?
Helicase
Given the rate law: rate=k [A]^2[B][C]^0
By what factor will the rate increase if the concentration of both A and C double?
Increase by at factor of 4
An audience member experiences sound of intensity I as an orchestra member plays a flute. If the audience member moves farther back so that the distance from the flute player is doubled, then I would:
decrease by a factor of 4.
I= 1/r^2
What is the term for a person's belief in their ability to successfully perform a particular behavior or accomplish a task?
self-efficacy
What is the test duration for either the MCAT or the DAT?
MCAT: 7.5 Hours
DAT: 5 Hours
A cell has 30% concentration of Water inside and a 35% concentration of NaCl in its environment. Assuming NaCl is the only solute in both environments, where will water move and what tonicity is this?
Water will move out of the cell into the environment, and the surrounding environment is hypertonic.
What is the major product when a tertiary alkyl halide reacts with a strong base under conditions favoring elimination?
the more substituted alkene (Zaitsev product)
An object is thrown straight upward with an initial velocity of 20 m/s. Ignoring air resistance, approximately how long does it take to reach its maximum height?
2 seconds (Use g = 10 m/s².)
A researcher finds that people who have higher levels of education tend to have better health outcomes. However, the researcher cannot determine whether education itself causes better health. What type of relationship has been demonstrated?
correlation
When can you register for each of the tests?
October 20–22, 2026 for MCAT, Anytime for DAT
