This molecule, shaped like a double helix, contains the genetic instructions used in the development and functioning of all living organisms.

What is DNA?

100

This gas, with the chemical symbol O, is essential for human respiration and makes up about 21% of Earth's atmosphere.

What is oxygen?

100

This thermodynamic quantity measures the degree of disorder, randomness, or uncertainty within a closed physical system.

What is entropy?

100

This English physicist formulated the laws of motion and universal gravitation after famously observing a falling apple.

Who was Sir Isaac Newton?

200

This astronomical term describes a massive region of space where gravity is so strong that nothing, not even light, can escape from it.

What is a Black Hole?

200

This organelle is famously known as the "powerhouse of the cell" because it generates most of the cell's chemical energy supply.

What is the mitochondria? (Accept: Mitochondrion).

200

This is the lightest and most abundant chemical element in the universe, making up roughly 75% of all baryonic mass.

What is hydrogen?

200

This law of physics states that energy can neither be created nor destroyed, only transformed from one form to another.

What is the Law of Conservation of Energy?

200

This German-born theoretical physicist developed the Theory of Relativity and came up with the world's most famous equation, E=mc2

Who was Albert Einstein?

300

This is the common name for the galaxy that contains our Solar System, named after its appearance as a dim glowing band across the night sky.

What is the Milky Way?

300

This chemical process is used by plants and other organisms to convert light energy into chemical energy, releasing oxygen as a byproduct.

What is photosynthesis?

300

This tabular arrangement organizes all known chemical elements by their atomic number, electron configuration, and recurring chemical properties.

What is the Periodic Table?

300

This physics concept, defined by Newton's First Law, is the tendency of an object to resist changes to its state of motion.

What is inertia?

300

This English naturalist formulated the theory of evolution by natural selection in his landmark 1859 book On the Origin of Species.

Who was Charles Darwin?

400

This parameter describes the boundary of a black hole beyond which no events can affect an outside observer; the point of no return.

What is the Event Horizon?

400

This green pigment, found inside plant chloroplasts, is responsible for absorbing light energy during photosynthesis.

What is chlorophyll?

400

This type of strong chemical bond involves the sharing of electron pairs between atoms.

What is a covalent bond?

400

This is the ultimate speed limit of the universe, traveling at approximately 300,000 kilometers per second in a vacuum.

What is the speed of light?

400

This Polish-French physicist and chemist pioneered research on radioactivity and became the first person to win two Nobel Prizes.

Who was Marie Curie?

500

This cooling, glowing remnant of a low-to-medium mass star represents the final evolutionary state of stars like our Sun after they shed their outer layers.

What is a White Dwarf?

500

This biological term describes a state of steady internal, physical, and chemical conditions maintained by living systems for optimal functioning.

What is homeostasis?

500

These substances speed up the rate of a chemical reaction without consuming themselves in the process.

What are catalysts? (Accept: Enzymes for biological context).

500

This fundamental force attracts any two objects with mass toward each other, keeping planets in orbit around the sun.

What is gravity?

500

This scientific theory states that the universe originated approximately 13.8 billion years ago from an extremely hot and dense singularity that expanded rapidly.
