🧬 Biology
This organ pumps blood throughout the human body.
What is the heart?
This type of bond forms when electrons are transferred from one atom to another.
What is an ionic bond?
This quantity is defined as mass times velocity.
What is momentum?
This layer of Earth is where we live.
What is the crust?
This scientist’s work Principia Mathematica laid out the laws of motion and universal gravitation.
Who is Isaac Newton?
This organelle contains enzymes that break down waste materials and cellular debris.
What is the lysosome?
This principle states that electrons fill lower-energy orbitals before higher-energy ones.
What is the Aufbau Principle?
This law states that the acceleration of an object is equal to the net force acting on it divided by its mass.
What is Newton’s Second Law?
This type of plate boundary occurs when two tectonic plates move away from each other, often forming new crust.
What is a divergent boundary?
This scientist’s voyage on the HMS Beagle heavily influenced his development of natural selection.
Who is Charles Darwin?
This process converts RNA into protein at the ribosome.
What is translation?
This term describes the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.
What is specific heat capacity?
This principle states that the total mechanical energy of a system remains constant if only conservative forces act on it.
What is the Law of Conservation of Energy?
This scale measures the magnitude of earthquakes based on seismic energy released.
What is the Richter scale?
This physicist conducted the oil drop experiment, helping determine the charge of the electron.
Who is Robert Millikan?
This structure in plant cells regulates the movement of gases and water vapor through tiny openings in leaves.
What are stomata?
This law states that the pressure of a gas is inversely proportional to its volume at constant temperature.
What is Boyle’s Law?
This phenomenon occurs when a wave changes direction as it passes from one medium to another due to a change in speed.
What is refraction?
This process describes the downward movement of dense oceanic crust beneath a less dense plate.
What is subduction?
This scientist proposed the uncertainty principle, a key concept in quantum mechanics.
Who is Werner Heisenberg?
This type of RNA carries amino acids to the ribosome during protein synthesis.
What is transfer RNA (tRNA)?
This concept describes the measure of disorder or randomness in a system.
What is entropy?
The speed of light is approximately this many miles per second (round to nearest thousand).
What is 186,000 miles per second?
This layer of Earth’s interior is composed mostly of liquid iron and nickel and is responsible for generating Earth’s magnetic field.
What is the outer core?
This physicist developed the concept of wave-particle duality and is known for the equation relating wavelength to momentum.
Who is Louis de Broglie?
