Life Science
the gatekeeper in the cell...controls what comes in and what goes out
cell membrane
the breaking down of earth's surface
weathering
materials that allow electricity to freely flow through them such as metals and water
conductors
the control center of the cell...also holds DNA (genetic material)
nucleus
materials that stop the flow of electricity such as rubber, wood, glass, foam, and air
insulators
an animal with a backbone
vertebrate
valleys, canyons, and sinkholes are all landforms created by this
destructive force
closed circuit
the movement of earth after it has been broken down
a warm-blooded vertebrate that has feathers, a beak, and lays eggs
bird
inherited
walls build along the sides of rivers to prevent flooding
levees
a permanent magnet
bar magnet
a behavior you are not born with...you learn to do it during your lifetime
acquired behavior
a broken pathway that does not allow electricity to freely flow
open circuit
a warm-blooded animal with a backbone, fur, and the ability to feed milk to its young
mammal
mountains, islands, sand dunes, and hills are landforms that are created by this
constructive force
a change that does not create a new substance such as tearing, cutting, sanding, melting, and dissolving
physical change
a magnet that is temporary because it can be turned on and off
electric magnet
a cold-blooded vertebrate that lays eggs and has scales and rough skin
reptile
A behavior you are born knowing how to do like breathing, flinching, etc.
instinct
the dropping of sediment to build earth's surface back up
deposition
gas is formed, temperature change, new color, residue
a cold-blooded reptile that lays eggs and has smooth, moist skin...often begins life in water and then moves to land
amphibian
the process of restoring the beach after erosion has happened (not talking about dredging)
beach nourishment
