Biology
This organelle is known as the “powerhouse of the cell.”
mitocondria
This subatomic particle carries a positive charge and is found in the nucleus.
proton
This functional group has the structure –OH.
alcohol
This branch of psychology focuses on diagnosing and treating mental disorders.
clinical psychology
This superhero is known as the “Caped Crusader” and protects Gotham City.
Batman
This type of RNA carries amino acids to the ribosome during protein synthesis.
The measure of a substance’s ability to donate or accept electrons in a redox reaction is called this.
oxidation state (or oxidation number)
This type of isomerism occurs when compounds have the same molecular formula but differ in the connectivity of their atoms.
structural (or constitutional) isomer
This type of conditioning, studied by Pavlov, involves learning through association.
classical conditioning
This music artist released the album 25 in 2015, featuring hits like “Hello.”
Adele
This level of protein structure is stabilized by hydrogen bonds between backbone atoms.
secondary structure
This type of bond forms when electrons are shared between two atoms.
covalent bond
In nucleophilic substitution, this mechanism involves a two-step process with a carbocation intermediate.
SN1
According to Freud, this part of personality operates on the “reality principle.”
ego
This streaming platform produces original shows like Stranger Things and The Crown.
Netflix
This cellular junction allows direct communication between neighboring animal cells.
gap junctions
This gas law states that at constant temperature, the pressure of a gas is inversely proportional to its volume.
Boyle’s law
This type of aromatic compound reacts with electrophiles in a substitution reaction and is stabilized by resonance with delocalized π electrons.
benzene ring
This cognitive bias occurs when people overestimate their ability to have predicted an event after it has happened.
hindsight bias
This British rock band released the album OK Computer in 1997, considered one of the greatest albums of all time.
Radiohead
This type of RNA molecule regulates gene expression by binding to complementary mRNA sequences, leading to their degradation or translational repression.
microRNA (miRNA)
This principle predicts how the position of a chemical equilibrium shifts when a system is stressed by changes in concentration, pressure, or temperature.
Le Châtelier’s principle
Predict the major product of the following reaction:
CH₃CH=CH₂ + HBr → ? (in the presence of peroxides)
The reaction is hydrobromination of an alkene.
Because peroxides are present, the reaction follows the anti-Markovnikov rule (radical mechanism).
The Br atom attaches to the less substituted carbon of the double bond.
Major product: CH₃CH₂CH₂Br (1-bromopropane).
This psychological phenomenon explains why individuals in a group may exert less effort when working collectively than when working alone.
social loafing
This Japanese animation director is famous for films like Spirited Away and My Neighbor Totoro.
