What is 70%?
These proteins in the blood act as catalysts to speed up chemical reactions.
What are enzymes?
This planet spins on its side.
What is Uranus?
This law states that, for every action, there is an equal and opposite reaction.
What is Newton's Third Law?
This atom is named for its yellowish-green color.
What is chlorine?
This renewable energy source uses the Earth's internal heat to produce electricity and heating.
What is geothermal energy?
The term for when there are more cases than expected in a certain population in a certain period of time
What is an outbreak?
This type of star is the final evolutionary stage of stars with masses similar to the Sun, characterized by a dense, hot core and no hydrogen fusion.
What is a white dwarf?
This law states that the total entropy of an isolated system increases over time.
What is the Second Law of Thermodynamics?
This English scientist formulated the laws of motion and universal gravitation, laying the groundwork for classical mechanics.
Who is Isaac Newton?
This phenomenon, in which burning fossil fuels and deforestatation largely contributes to by increasing atmospheric carbon dioxide, traps heat near Earth's surface
What is the greenhouse effect?
This organ regulates sugar, and its malfunction can lead to diabetes
What is the pancreas?
This is the name of the satellite launched by NASA in 1977, which carried a golden phonograph.
What is Voyager I?
This process involves combining two light atomic nuclei to form a heavier nucleus, releasing energy, and is the principle behind hydrogen bombs and the sun's energy production.
What is nuclear fusion?
This American biologist raised awareness of the dangers of pesticide use and environmental pollution in her groundbreaking book "Silent Spring" in 1962.
Who is Rachel Carson?
This term refers to the maximum amount of water vapor air can hold at a given temperature before condensation occurs.
What is saturation point?
This small structure located at the base of the brain is known as the "master gland" because it regulates vital bodily functions through the release of hormones.
What is the pituitary gland?
This is commonly referred to as the "point of no return" when referring to a black hole and is when the gravitational pull of the black hole captures everything that enters it, including light.
What is the event horizon?
This angle is the optimal angle to launch a projectile to achieve the farthest distance (if air resistance is negligible).
What is 45°?
This person was the first American astronaut in space.
Who is Alan Shepard?
This climate agreement was signed in 2016 to "strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels."
Hint: The U.S. withdrew from this agreement in 2017 and rejoined in 2021.
What is the Paris Agreement?
This enzymatic technique is used to amplify a specific DNA sequence exponentially, commonly used in genetics research, medical diagnostics, and forensic science. Must say full acronym.
What is Polymerase Chain Reaction (PCR)?
This hypothetical form of energy is believed to be responsible for the accelerated expansion of the universe, comprising approximately 68% of the total energy in the present-day cosmos.
What is dark energy?
This fundamental theory of particle physics combines classical field theory, special relativity, and quantum mechanics, and is the basis for understanding the interactions between particles.
What is quantum field theory?
Tthis project, completed in 2003, was an international scientific research project with the goal of determining the sequence of nucleotide base pairs that make up human DNA, and identifying and mapping all of the genes of the human genome.
What is the Human Genome Project?
