Weighing about 8 pounds on an adult human, this is the single largest organ in the human body.
What is the skin.
This invisible force keeps us grounded on Earth and is the weakest of the four fundamental forces of nature.
What is gravity?
In 1847, this Italian chemist first synthesized nitroglycerin, though he originally warned others against using it due to its extreme volatility.
Who is Ascanio Sobrero?
The periodic table organizes its elements by this specific number, which equals the count of protons in an atom.
What is an Atomic Number?
This is the largest planet in our solar system.
What is Jupiter?
This is the primary green pigment that plants use to absorb light during photosynthesis.
What is chlorophyll?
his five-letter science term describes a volcano that hasn't erupted in many years but still has the potential to wake up.
What is dormant?
To make nitroglycerin safer to transport, Alfred Nobel mixed it with this porous, sedimentary earth to create dynamite.
What are nitro compounds (or organic nitrates)?
This subatomic particle orbits the nucleus and carries a negative electrical charge.
What is an electron?
This event occurs when the Moon passes directly between the Earth and the Sun, temporarily blocking out the sunlight.
What is a Solar eclipse?
In genetic engineering, the acronym "CRISPR" refers to a powerful technology used primarily for this precision purpose.
What is gene editing?
Making up roughly 78% of the air we breathe, this is the most abundant gas in Earth's atmosphere.
What is nitrogen?
Surprisingly, small doses of nitroglycerin are prescribed in medicine to treat this severe, squeezing chest pain by widening the body's blood vessels.
What is angina (or angina pectoris)?

What is Jupiter
While the "NA" stands for nucleic acid, the "D" in DNA stands for this specific sugar.
What is deoxyribose?
This scale, ranging from 1 to 10, is used by geologists to compare the relative hardness of different minerals.
What is the Mohs scale?
In chemical terms, nitroglycerin doesn't just burn; it undergoes this hyper-fast reaction where a supersonic shockwave passes through the material, causing an instant explosion.
What is detonation?
With a melting point over 6,100°F, this chemical element represented by the symbol "W" has the highest melting point of all metals.
What is tungsten?
Protons, neutrons, and electrons make up regular matter, but scientists believe this mysterious, invisible force makes up roughly 70% of the universe.
What is Dark Energy
Cellular respiration relies on this specific metabolic cycle, named after a British biochemist, which occurs inside the mitochondria to generate ATP.
What is the Krebs cycle?
This geological theory suggests that the movement of liquid iron in Earth's outer core is what generates our planet's magnetic field.
What is the dynamo theory?
TNT stands for?
