photon
particle of electromagnetic (light) energy
transcription
in biology, transcription is the prodiction or RNA using DNA as a template
potential energy
stored energy available to do work
igneous rocks
when pre- existing rocks are heated until they completely malt and then are allowed to
cool, igneous rock is created
friction
a force that resists the movement of two objects rubbing against each other
isotopea
a variation of an element in which there are a different number of neutrons in the
necleus
absorance
the amount of light eergy transferred to an object; dark objects tend to take in more
energy then light objects, beacuse light objects tend to reflect energy
subduction zones
regions where two geologic plates in the earth overlap, forcing one plate under the other
(subduction)
amino acid
the building blocks of proteins
kinetic energy
energy of motion, in direct proportion with either the mass or velocity of an object
precipitate
a solid that froms from a liquid mixture
photosynthesis
the process by which plants use light to first form chemical energy and then use that
chemical energy to produce sugars from carbon dioxide
subatomic particles
the parts of an atom
pH
a scale from 0-14 measuring how acid or basic a substance is; a pH< 7 is acidic, a pH>
7 is basic, and pH= 7 is neutralenzyme
molecules, typically protiens, that increase the speed of cemical reactions in the body
viscosity
the resistance to flow; a measure of how thick a liquid is
altitude
distance above sea level
sedimentary rock
rocks produced by small particles, deposited by wind or water, then fused by pressure
and heat into solid rock
bedrock
a layer of rock that lies beneath soil, dirt, or gravel
corrosion
the breakup of material due to chemical reactions
diffusion
movement of substances from areas with high concentrations to areas with low
concentrations
permeableallows the movement of certain substances across a barrier
serum
a plasma substance containing all blood protiens not used in clotting. it is neither a
blood cell, nor a clotting factor
metaphoric rock
rocks produced by applying pressure and heat to an existing rock in order to change its
form without completely melting it
buoyancy
a property of a liquid that supports a submerged object with a force equal to the weight
of the liquid that is displaced by the object
polymers
large molecules that consist of collections of smaller units
phenotype
an observable trait of an individual that is determined by his or her genetics
chlorophyll
a green protein within plants that converts light into usable energy
chromosomes
large DNA molecules that contain the encoded genetic information of a cell
greenhouse gasses
gases in the stmosphere that keep light energy near the surface, keeping the planet
warmer
climate
the average weather of a region over a long period of time
conduction
the measure of a material's ability to carry an electrical current
