Biology

100

anything that has mass and takes up space

matter

100

an association of living organisms and their environment

ecosystem

100

the ability to produce more cells

reproduction

100

Non living, not derived from living things.

abiotic

200

The collected body of data from experiment and observation

evidence

200

a collection of atoms that all have the same number of protons

elements

200

the specific environment of an organism including biotic and abiotic

habitat

200

a jelly-like fluid inside the cell in which the organelles are suspended

cytoplasm

200

The tendency of energy to disperse and become less available to do work.

 Entropy

300

observations involving numbers such as counting and measuring

Quantative observations

300

chemicals that result when two or more atoms are joined together chemically

molecule

300

a close relationship between two or more species where at least one of them benefits

symbiosis

300

double membraned bound organelles in which nutrients are converted into energy

mitochondria

300

 A substance that changes the rate of a chemical reaction but is not itself used up or affected by the reaction.

Catalyst

400

observations that are not based on not easily counted or measured such as color or texture

Qualitative observations

400

positively or negatively charged atoms resulting from the transfer of electrons

Ion

400

the process by which certain gasses trap heat that would otherwise escape the earth and radiate into space

greenhouse effect

400

random motion of molecules from a high area of concentration to a low area of concentration until concentration becomes equal

diffusion

400

The number of of organisms in a defined unit of area.

Population Density

500

logical interpretation based on prior knowledge, experience, or evidence

Inference

500

an attractive force that holds molecules of the same substance together

cohesion

500

a relationship between two or more organisms of different species where all benefit from the association

mutualism

500

the diffusion of water through a semi-permeable membrane from area of high water concentration to an area of low water concentration OR low solute concentration to a high solute concentration.
