Heredity
Process in which a single cell divides into two identical daughter cells
Mitosis
Type of galaxy that has an elliptical or oval shape
Elliptical Galaxy
Thin, flexible barrier that surrounds and protects the contents of a cell
Cell Membrane
Process of wearing away rocks, soil, and other materials on the Earth’s surface through the action of wind, water, ice, and other natural forces
Erosion
Property of a substance that allows it to be hammered, rolled, or bent into different shapes without cracking or breaking apart
Malleability
Process of cell division that occurs in sexually reproducing organisms, involving two rounds of division
Meiosis
Tendency of an object to resist changes in its state of motion
Inertia
Powerhouse of the cell. Small, bean-shaped organelles that are found in the cytoplasm of most cells
Mitochondria
Process by which water vapor in the atmosphere condenses into droplets or ice crystals and falls to the Earth’s surface, can take the form of rain, snow, sleet, or hail
Precipitation
The way light reflects off the surface of an object
Luster
An individual who has two different alleles for a particular gene
Heterozygous
Occurs when the Earth comes between the Sun and the Moon, causing the Moon to pass through Earth’s shadow
Lunar Eclipse
Brain of the cell. Membrane-bound organelle that contains the cell’s genetic material
Nucleus
Process by which liquid water changes into water vapor and enters the atmosphere
Evaporation
A way to measure how acidic or basic a substance is
pH
An individual who has two identical alleles for a particular gene
Homozygous
Type of tide that occurs when the Sun, Moon and Earth are aligned in a straight line
Spring Tide
Process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen
Photosynthesis
Process by which water vapor in the air cools down and changes back into liquid water
Condensation
Formed when an atom gains or loses electrons, giving it a positive or negative charge.
Ion
Stands for deoxyribonucleic acid. It is a molecule that carries the genetic instructions used in the development, functioning, and reproduction of all living organisms
DNA
Phase of the Moon when it appears to be getting smaller and less illuminated
Waning
Movement of water molecules across a semi-permeable membrane from an area of lower concentration to an area of higher concentration, water trying to balance things out
Osmosis
Process by which plants release water vapor from their leaves into the atmosphere
Transpiration
Substances that undergo a chemical change when they come together
Reactants
