    • Plants convert sunlight into chemical energy through photosynthesis.

    Cell Membrane

    • The cell membrane controls what enters and leaves the cell.

    Liver Functions

    • The liver does not produce insulin.

    Decomposers

    • Organisms that break down dead organic matter are called decomposers.

    Red Blood Cells

    • Red blood cells are responsible for transporting oxygen throughout the body.

    Cerebellum Function

    • The cerebellum is the part of the brain responsible for balance and coordination.

    Covalent Bonds

    • When two atoms share electrons, they form a covalent bond.

    Endocrine System Function

    • The endocrine system primarily regulates hormone production and release.

    Basic Unit of Life

    • The basic unit of life is a cell.

    Genotype

    • The genetic makeup of an organism is called its genotype.

    Kinetic Energy Formula

    • The formula for calculating kinetic energy is KE = 1/2 * mv^2, where KE is kinetic energy, m is mass, and v is velocity.

    Resistance Unit

    • The unit used to measure electrical resistance is the ohm.

    Mechanical Waves

    • Mechanical waves require a medium to propagate.

    Refraction

    • Refraction is the bending of light when it transitions between mediums.

    Plate Tectonics Theory

    • The theory that explains the movement of tectonic plates is called plate tectonics.

    Potential Energy

    • A stretched rubber band exemplifies potential energy.

    Earth's Atmosphere Composition

    • Nitrogen constitutes the majority of Earth's atmosphere.

    Geological Time Scale

    • The geological time scale is primarily used for organizing Earth's history.

    Igneous Rocks

    • Igneous rocks are formed by the cooling and solidification of magma.

    Evaporation

    • Evaporation describes the transformation of liquid water into vapor.

    Transform Fault

    • A transform fault is characterized by tectonic plates sliding horizontally past each other.

    Inner Core Composition

    • Earth's inner core is primarily composed of iron.

    Minerals

    • A naturally occurring solid material made up of one or more minerals is called a mineral.

    Mohorovičić Discontinuity

    • The boundary or discontinuity between the mantle and the core is called the Mohorovičić Discontinuity.

    Charles's Law

    • Charles's Law states that the volume of a gas is directly proportional to its temperature in kelvins, given constant pressure and number of particles.

    Osmosis

    • Osmosis represents the natural movement of water across a semipermeable membrane.

    Isomers

    • Compounds that have the same molecular formulas but different structural formulas are called isomers.

    Ribosomes

    • Ribosomes are primarily responsible for the assembly of proteins within a cell.

    Sexual Reproduction

    • Sexual reproduction involves the fusion of male and female gametes to produce offspring.

    Combustion Reactions

    • In a combustion reaction, oxygen combines with a hydrocarbon, releasing energy and producing carbon dioxide and water.

    Immune System Function

    • The primary function of the immune system is to protect the organism from disease-causing agents.

    Genes

    • A segment of DNA or RNA that codes for a protein or RNA is called a gene.

    Concave Lenses

    • Concave lenses form virtual, upright, and smaller images.

    Sodium Chloride Formula

    • The chemical formula for sodium chloride is NaCl.

    Noble Gases

    • Helium is classified as a noble gas.

    Hypothalamus

    • The hypothalamus is a gland found in the brain that links the nervous system to the endocrine system.

    Endothermic Reactions

    • Endothermic reactions absorb heat from their surroundings.

    Acid-Base Indicator

    • A strong acid introduced to blue litmus paper will turn it red.

    Supersaturated Solutions

    • A supersaturated solution contains more solute than can typically be dissolved at a specified temperature.

    Unit of Force

    • The unit of measure for force in the International System of Units (SI) is the Newton (N).
