your skin cells do this to divide (2n = 46 chromosomes in each of your skin cells)

mitosis

100

Organisms that can reproduce through fruiting bodies and can send out spores. They are some of the largest organisms in the world! 

fungi

100

The rate at which an object changes its position in a specific direction

velocity

100

The process by which an oceanic tectonic plate sinks under another plate into Earth's mantle

subduction

100

The specific role, position, or "functional job" an organism plays within its ecosystem, including how it uses resources and interacts with biotic (living) and abiotic (non-living) factors

niche 

200

A two-step cell division process in sexually reproducing organisms that reduces the chromosome number by half, producing four genetically unique haploid gametes from one diploid parent cell

Meiosis

200

The green photosynthetic pigment found chiefly in the chloroplasts of plants

chlorophyll

200

The natural tendency of an object to resist changes in its state of motion

Inertia

200

The point on Earth's surface directly above the focus of an earthquake

epicenter

200

The evolutionary process by which populations evolve to become distinct, reproductively isolated species

speciation

300

The metabolic process where cells break down glucose and other organic molecules in the presence of oxygen (aerobic) to produce energy in the form of ATP

cellular respiration

300

The biochemical process by which some organisms convert light energy (usually from the sun) into chemical energy (ATP)

photosynthesis

300

The rate of change of an object's velocity with respect to time, involving a change in speed, direction, or both

acceleration

300

An instrument that constantly records ground movements.

seismograph

300

Remnants of structures that were functional in ancestors but are now reduced or non-functional.

Vestigial Structures

400

These are membrane bound organelles that generate most of the cell's supply of energy (ATP) 

mitochondria

400

The energy currency/molecule that we use in our cells! 

adenosine triphosphate (ATP)

400

The branch of physics that studies the relationships between heat, work, temperature, and energy

thermodynamics

400

A water wave cause by an earthquake, volcanic eruption or landslide.

tsunami

400

A self-regulating process by which biological systems maintain a stable, relatively constant internal environment despite changes in external conditions

homeostasis

500

A network of membranes, tubes, and sacs within a cell that acts as a transport and production factory, responsible for making, folding, and exporting proteins and lipids. (Hint: there are two types)

endoplasmic reticulum

500

The molecule that carries genetic information for the development, function, and reproduction of all known living organisms

deoxyribonucleic acid 

500

One of the four fundamental forces of nature, describing the interactions between electrically charged particles and the magnetic fields they create

electromagnetism

500

The layer in Earth's upper mantle and directly under the lithosphere in which rock is soft and weak because it is close to melting.

asthenosphere

500

A type of symbiotic relationship in biology where one organism benefits, while the other is neither helped nor harmed

commensalism
