Chemistry
This type of chemical reaction involves a single element swapping places with an ion in a compound, famously demonstrated when copper wire is dropped into silver nitrate.
What is a single-replacement reaction?
Unlike velocity, which requires a specific direction, this scalar quantity describes only the magnitude of how fast an object is moving.
What is speed?
Often dubbed the "powerhouse of the cell," this organelle is the primary site where cellular respiration takes place to generate ATP.
What is the mitochondrion?
Distinct from daily weather, this term refers to the long-term average of atmospheric conditions and patterns in a region over a period of 30 years or more.
What is climate?
This natural mechanism traps thermal energy in Earth’s atmosphere using gases like carbon dioxide, methane, and water vapour, keeping the planet warm enough to sustain life.
What is the greenhouse effect?
According to Alberta's solubility guidelines, this is the term used to describe an ionic compound that does not dissolve well in water and settles out as a solid precipitate.
What is insoluble?
Newton’s first law of motion is often referred to by this 7-letter word, which describes an object's natural resistance to any change in its state of motion.
What is inertia?
Found mostly on the undersides of leaves, these microscopic pores open and close to regulate gas exchange and water loss through transpiration.
What are stomata?
This type of tectonic plate boundary occurs where two crustal plates are pulling away from each other, famously creating the Mid-Atlantic Ridge.
What is a divergent boundary?
Essential for relative dating in geology, this law states that in an undisturbed sequence of sedimentary rock, the oldest layer is always at the bottom.
What is the Law of Superposition?
For an ideal gas, this law states that the volume is inversely proportional to its pressure, meaning if you squeeze a gas into half the space, the pressure doubles.
What is Boyle's Law?
This specific, net "center-seeking" force is what keeps an object moving at a constant speed along a curved or circular path.
What is centripetal force?
This major, thick-walled blood vessel breaks the standard "rule" by carrying completely deoxygenated blood away from the right ventricle toward the lungs.
What is the pulmonary artery?
This ecological concept describes the predictable, gradual process by which an ecosystem recovers and changes its community structure over time following a major disturbance like a wildfire.
What is ecological succession?
These fast-moving, longitudinal seismic waves are the very first to arrive at a monitoring station during an earthquake, and they can travel through both solid and liquid rock.
What are P-waves?
In organic chemistry, this is the class of unsaturated hydrocarbons that contains at least one carbon-to-carbon triple bond.
What is an alkyne?
This vector quantity is defined as the product of the net force acting on an object and the time interval over which that force is applied.
What is impulse?
This specific process of cell division involves two consecutive rounds of separation and results in four genetically distinct haploid daughter cells.
What is meiosis?
Unlike finite fossil fuels, energy resources like solar, wind, biomass, and geothermal are grouped under this sustainable category.
What are renewable resources?
Spanning from low-energy radio waves to high-energy gamma rays, this entire continuous range of wavelengths is used by astronomers to study the universe.
What is the electromagnetic spectrum?
According to the Brønsted-Lowry theory, this specific term describes the chemical species that remains after a Brønsted-Lowry acid has donated its proton.
What is a conjugate base?
This phenomenon, which won Einstein his Nobel Prize, occurs when light of a sufficiently high frequency hits a metal surface and ejects electrons from it.
What is the photoelectric effect?
Produced by the hypothalamus and released by the pituitary, this hormone acts directly on the nephrons' collecting ducts to increase water reabsorption when you're dehydrated.
What is antidiuretic hormone?
This non-invasive medical imaging technology utilizes powerful magnetic fields and radiofrequency pulses to map out soft tissues without exposing the patient to ionizing radiation.
What is Magnetic Resonance Imaging?
This cosmological phenomenon occurs when light from a distant star or galaxy shifts toward longer wavelengths as it moves away from Earth, proving that the universe is expanding.
What is redshift?
