Science Flashcards
Resistance
Makes it difficult for current to flow
Acid+metal
Salt+hydrogen
Acid+carbonate
Water+salt+carbon dioxide
Surface area to volume ratio
As the surface area increases the surface to volume ratio decreases
A voltmeter must be connected in
Parallel to a component
Adaptation
Changes in a organism over time to fit a location
Ecosystem
A collection of organisms in an area along with important environmental factors
Cell
Pushes the current around the circuit
A ammeter must be connected in
Series to a component
Habitat
The area where organisms live
A battery
Is two or more cells
Pyramid of numbers
Shows us how many organisms are at each trophic level
Community
All the organisms living in an area
Pyramid of biomass
Dry mass of all living organisms always pyramidal in shape
Acid+base
Water+salt
Resistance is measured in
Ohms Ω
Current
The flow of positive charge through a conductor per second
Resistance
Makes it difficult for current to flow
Population
All the organisms in a species in an area
True or false magnetic fields go south to north
False
