Biology
This is the basic structural and functional unit of all living things
What is a cell?
This negatively charged subatomic particle orbits the nucleus of an atom.
What is an electron?
This is the SI (metric) unit used to measure force.
What is the newton?
This is the closest star to Earth and the main source of energy for life on our planet.
What is the Sun?
This molecule, shaped like a double helix, stores and carries the genetic instructions for an organism.
What is DNA?
Elements arranged in the same vertical column of the periodic table share this name, and generally have similar chemical properties.
What is a group?
According to Newton's First Law, an object at rest or in motion will stay that way unless acted on by this.
What is an unbalanced force?
This continuous process describes the movement of water between the atmosphere, land, and oceans through evaporation, condensation, and precipitation.
What is the water cycle?
This type of cell division produces two genetically identical daughter cells and is used for growth and repair.
What is mitosis?
This type of chemical bond forms when one or more electrons are transferred from a metal atom to a nonmetal atom.
What is an ionic bond?
This equation, part of Newton's Second Law, relates force, mass, and acceleration.
What is F = ma?
This layer of Earth's atmosphere is closest to the surface and is where nearly all weather occurs.
What is the troposphere?
This type of cell division produces four genetically different daughter cells, each with half the normal number of chromosomes, and is essential for sexual reproduction.
What is meiosis?
This law states that matter cannot be created or destroyed in a chemical reaction, which is why chemical equations must be balanced.
What is the Law of Conservation of Mass?
This form of energy is associated with an object's motion and can be calculated using one-half times mass times velocity squared.
What is kinetic energy?
This theory explains that Earth's surface is broken into large plates that move slowly over time, causing earthquakes, volcanoes, and the formation of mountains.
What is plate tectonics?
This term refers to the observable physical or biochemical characteristics of an organism, resulting from the interaction of its genes and its environment.
What is phenotype?
What temperature in celsius is considered absolute zero?
What is 273°C?
This law states that energy cannot be created or destroyed, only transformed from one form into another.
What is the Law of Conservation of Energy?
This term describes the amount of time it takes for half of the radioactive atoms in a sample to decay, and is used by scientists to date rocks and fossils.
What is half-life?
