Life Science
Human body system primarily responsible for gas exchange, including taking in oxygen and releasing carbon dioxide.
What is the respiratory system?
In the hydrologic cycle, liquid water absorbs thermal energy from the environment to transition into water vapor.
What is evaporation?
This gas law states that at a constant temperature, reducing the volume of a gas sample causes its pressure to increase proportionally.
What is Boyle's Law?
Cantilevered load-bearing structures in Boomilever are constructed using adhesives and this fibrous natural building material.
What is balsa wood?
This classic communication code represents letters and numbers using short and long signals known as dots and dashes.
What is Morse Code?
This specialized vascular tissue in plants conducts water and dissolved minerals upward from the roots to the leaves.
What is xylem?
This major rock family forms directly from the cooling and crystallization of molten magma or lava.
What are igneous rocks?
According to Ohm's Law, if a 12-volt potential difference is applied across a 6-ohm resistor, this amount of electric current flows through the circuit.
What is 2 amperes?
Electric vehicles convert chemical energy stored in batteries into this form of mechanical energy to move down the track.
What is kinetic energy?
In computer programming languages like Python or Java, text characters enclosed inside quotation marks belong to this data type.
What is a string?
In an epidemiological outbreak investigation, this metric measures the rate of new cases of a disease occurring in a population over a given period.
What is incidence?
Carrying the Messier catalog designation M31, this spiral galaxy is the nearest major galactic neighbor to our Milky Way.
What is the Andromeda Galaxy?
This analytical technique uses a solvent mobile phase rising up a thin coated plate to separate components of a mixture.
What is Thin Layer Chromatography?
Air-cushion vehicles levitate on a cushion of high-pressure air to reduce this specific force that opposes the relative sliding motion of two solid surfaces moving against each other.
What is kinetic friction?
In a controlled scientific experiment, this single factor is intentionally varied or manipulated by the researcher to test a hypothesis.
What is the independent variable?
In molecular genetics, this process uses the enzyme RNA polymerase to synthesize an RNA molecule from a DNA template strand.
What is transcription?
Rapid increases in these two primary agricultural nutrient pollutants in runoff frequently trigger harmful algal blooms (HABs) in marine and estuarine environments.
What are nitrates and phosphates?
According to Archimedes' principle, an object immersed in a fluid experiences an upward buoyant force equal to this property of the displaced fluid.
What is weight (force of gravity)?
In engineering design, the three-letter abbreviation CAD stands for this computer software category.
What is Computer-Aided Design?
Winding a rubber band motor stores energy in this form, which is released as kinetic energy to turn the airplane propeller.
What is elastic potential energy?
When extreme heat or pH changes disrupt a protein's tertiary structure without breaking its peptide bonds, it loses its biological function through this process.
What is denaturation?
This term refers to the fraction or percentage of incoming solar radiation reflected by a surface, such as ice or snow, back into space.
What is albedo?
The Second Law of Thermodynamics states that in any spontaneous physical or chemical process, the total measure of disorder in an isolated system, known by this term, must increase over time.
What is entropy?
Using an inclined plane allows an engineer to reduce the required input force needed to lift a heavy object by increasing this parameter.
What is displacement/distance?
When balancing a scale, equal masses balance horizontally because the clockwise and counterclockwise rotational forces, known by this term, are equal.
What is torque?
