100

Process in which a single cell divides into two identical daughter cells

Mitosis

100

Type of galaxy that has an elliptical or oval shape

Elliptical Galaxy

100

Thin, flexible barrier that surrounds and protects the contents of a cell

Cell Membrane

100

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

100

Property of a substance that allows it to be hammered, rolled, or bent into different shapes without cracking or breaking apart

Malleability

200

Process of cell division that occurs in sexually reproducing organisms, involving two rounds of division

Meiosis

200

Tendency of an object to resist changes in its state of motion

Inertia

200

Powerhouse of the cell. Small, bean-shaped organelles that are found in the cytoplasm of most cells

Mitochondria

200

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

200

The way light reflects off the surface of an object

Luster

300

An individual who has two different alleles for a particular gene

Heterozygous

300

Occurs when the Earth comes between the Sun and the Moon, causing the Moon to pass through Earth’s shadow

Lunar Eclipse

300

Brain of the cell. Membrane-bound organelle that contains the cell’s genetic material

Nucleus

300

Process by which liquid water changes into water vapor and enters the atmosphere

Evaporation

300

A way to measure how acidic or basic a substance is

pH

400

An individual who has two identical alleles for a particular gene

Homozygous

400

Type of tide that occurs when the Sun, Moon and Earth are aligned in a straight line

Spring Tide

400

Process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen

Photosynthesis

400

Process by which water vapor in the air cools down and changes back into liquid water

Condensation

400

Formed when an atom gains or loses electrons, giving it a positive or negative charge.

Ion

500

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

500

Phase of the Moon when it appears to be getting smaller and less illuminated

Waning

500

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

500

Process by which plants release water vapor from their leaves into the atmosphere

Transpiration

500

Substances that undergo a chemical change when they come together

Reactants
