General
100

This organelle contains enzymes for intracellular digestion.

Lysosome

100

This type of bond forms when electrons are transferred from one atom to another.

Ionic

100

This is the rate of change of velocity.

Acceleration

100

This type of rock forms from the accumulation of sand and other weathered pieces of rock

Sedimentary Rocks

100

This is the smallest unit of matter that retains the properties of an element.

Atom

200

This process allows water to move across a selectively permeable membrane from low solute concentration to high solute concentration.

Osmosis

200

The pH of a solution with high hydrogen ion concentration is described as this.

Acidic

200

This law states that an object in motion stays in motion unless acted upon by a net external force.

Newton's First Law/Law of Inertia

200

This instrumentis used to detect and record earthquake waves


seismograph

200

This layer of the atmosphere is where most weather occurs.

Troposphere

300

This stage of mitosis is when sister chromatids separate and move toward opposite poles.

Anaphase

300

This principle explains how increasing temperature affects the rate of a chemical reaction.

Collision Theory

300

This form of energy depends on both mass and height.

Gravitational Potential Energy

300

This boundary occurs when two tectonic plates slide past each other.


Transform Plate Boundary

300

This type of energy is stored energy due to position or configuration.

Potential Energy

400

This blood component is responsible for transporting oxygen using hemoglobin.

Red Blood Cells

400

This gas is produced when acids react with carbonates.

Carbon dioxide

400

This device is used to measure electric current in a circuit.

Ammeter

400

This internal layer of the Earth is composed mostly of liquid iron and nickel.

Outer Core

400

This stage of a star occurs after it has exhausted hydrogen in its core and expands significantly.


Red Giant Stage

500

This evolutionary concept explains how two species become different due to geographic separation.

allopatric speciation

500

This quantity is defined as the amount of solute dissolved per liter of solution.

Molarity

500

This principle explains why airplanes are able to lift off the ground due to pressure differences in airflow.

Bernoulli’s Principle

500

This process describes the movement of Earth’s plates due to heat-driven currents in the mantle.

Mantle Convection

500

This law, developed by Johannes Kepler, states that planets move faster when they are closer to the Sun.

Kepler's Second Law/Law of Equal Areas
