Units of Measurement
The force of gravity on an object
Weight
A testable explanation of a situation, supported by research
Hypothesis
Molecules that contains carbon and come from something living
Organic Molecule
When the concentration of particles on both sides of a membrane is equal
Equillibrium
Omniovore
The amount of matter in an object
Mass
The factors/variables in an experiment that stays the same
Control Variable
Molecule that has opposing slightly negative and slightly positive ends
Polarity
The ability of a membrane to allow substances to move across it
Permeability
Organism that can produce its own energy and food from sunlight
Autotroph
The amount of space taken up by an object
Volume
The group in an experiment without the independent variable or no change in the independent variable
Control Group
A macromolecule made up of smaller parts, a single unit
Monomer
Movement of particles across a membrane without the expenditure of energy
Passive Transport
Organism that obtains its energy by eating other organism
Heterotroph
What is the amount of kinetic energy in an object's particles?
Temperature
The factor of an experiment that is changed by the scientist
Independent Variable
A chain or group of macromolecules bonded together
Polymer
When energy is required to move particles across a membrane
Active Transport
Each step in a food chain or web
Trophic Level
The amount of matter in a given amount of space
Density
The factor of an experiment that is affected by the experiment
Dependent Variable
When a protein loses its shape, thus preventing it from performing its function
Denaturation
Movement of particles across a membrane only through specific channels
Facilitated Diffusion
Shows the amount of available energy at each trophic level
Energy Pyramid
