What is an ampere (or amp)?
These tiny air sacs in the lungs are where gas exchange occurs between oxygen and carbon dioxide.

On the periodic table, elements in the same vertical column share similar chemical properties and are called this.
What is a group (or family)?
This artist released the album "Midnights" in 2022
Who is Taylor Swift?
This Australian animal is the only mammal known to have electroreception, using sensors in its bill to detect prey underwater.
What is a platypus?
According to Newton's Third Law, for every action there is an equal and opposite one of these.
What is a reaction?
This process, occurring in the chloroplasts, converts light energy, carbon dioxide, and water into glucose and oxygen.
What is photosynthesis?
This type of chemical reaction releases energy to the surroundings, often in the form of heat, and includes combustion reactions.
What is an exothermic reaction?
This 2022 A24 film starring Michelle Yeoh features multiverse-hopping and won seven Academy Awards including Best Picture, becoming the most awarded film in Oscar history.
What is Everything Everywhere All at Once?
This town in South Australia is known as the "Opal Capital of the World" and many residents live underground in dugouts to escape the extreme heat.
What is Coober Pedy?
This phenomenon occurs when a system is driven at its natural frequency, causing dramatic increases in amplitude, famously demonstrated by the Tacoma Narrows Bridge collapse in 1940.
What is resonance?
This enzyme, discovered by Kary Mullis, is heat-stable and essential for PCR (polymerase chain reaction), originally isolated from bacteria living in hot springs.
What is Taq polymerase?
This principle states that when a system at equilibrium is disturbed, the system shifts to counteract the disturbance and establish a new equilibrium, named after a French chemist.
What is Le Chatelier's principle?
This rapper's 2024 feud with Drake produced multiple diss tracks including "Not Like Us" and "Euphoria," dominating hip-hop headlines.
Who is Kendrick Lamar?
This Australian Prime Minister served for only 8 days in 1945, making him the shortest-serving PM in Australian history before dying in office.
Who is Frank Forde?
This effect causes the observed frequency of a wave to change when there is relative motion between the source and observer, explaining why ambulance sirens change pitch as they pass.
What is the Doppler effect?
This type of cell division error occurs when chromosomes fail to separate properly during meiosis, resulting in gametes with an abnormal number of chromosomes, such as in Down syndrome.
What is nondisjunction?
This type of intermolecular force occurs between molecules with permanent dipoles and is stronger than dispersion forces but weaker than hydrogen bonds.
What are dipole-dipole forces?
This HBO series based on a video game franchise stars Pedro Pascal and Bella Ramsey surviving in a post-apocalyptic world filled with fungal zombies.
What is The Last of Us?
This 1854 rebellion at a goldfield in Ballarat saw miners revolt against colonial authority, resulting in the raising of the Eureka flag and becoming a significant moment in Australian democracy.
What is the Eureka Stockade?
This dimensionless number in fluid dynamics represents the ratio of inertial forces to viscous forces, determining whether flow will be laminar or turbulent.
What is the Reynolds number?
This mechanism of evolution occurs when a small group breaks away from a larger population to establish a new population, resulting in reduced genetic diversity and different allele frequencies.
What is the founder effect?
This type of isomer has the same molecular formula and connectivity but different spatial arrangements that cannot be interconverted without breaking bonds, such as cis-trans isomers.
What are stereoisomers (or geometric isomers)?
This auteur director released "Oppenheimer" in 2023, a biographical film about the physicist who led the Manhattan Project, winning seven Academy Awards.
Who is Christopher Nolan?
This Australian state was originally known as Van Diemen's Land until 1856, named after the Dutch explorer who first charted it.
