Homestasis
The ability or tendency of an organism or
cell to maintain a stable internal
environment when its external environment
is changing.
Recessive
This form of the gene would be masked or
covered by the dominant form. The only
way a recessive trait is expressed is when
there is not a dominant allele present.
Oxidation
Combine Oxygen with another substance
Ion
electrically charged atom
Brittle
can't change shape easily without braking,
easily broken, fragile, not flexible
Valence Electrons
electrons in the outer shell of the atom
Speed
The Distance traveled in a certain time
period (rate of motion)
Density
the measure of how much matter is in a
given amount of space or how tightly the
atoms are packed together. Density is
why the M&Ms fall to the bottom of the
trail mix and the Chex are on top..
Precipitant
Formation of a solid that forms in a
chemical reaction
Gravity
is the pull that all matter exerts on other
matter
Endothermic
Reaction
A chemical reaction where heat is absorbed
and it turns cold.
Friction
A force that resists motion between two
surfaces that are touching. This includes
air resistance.
Steady State
Theory
This universe has always been there and
always will be there.
Oscillating Theory
The universe is in a cycle of expanding and
contracting
Nebula
a huge cloud of gas and dust in outer space
that contract due to gravity and make a star
Greenhouse Effect
a very good and necessary "sweater of
gases" around the earth that prevents
extreme temperature changes
Percolation
Water soaking into the ground through soil
and rock
Algal Bloom
When too much nitrogen is used for
fertilization and the excess runs off and
enters water ecosystems, the algae
multiplies too quickly and turn the pond
thick green and blocks sunlight.
Nitrogen Fixation
The process where nitrogen gas must is
changed into a usable form by bacteria in
roots of certain plants called legumes
Convection
Currents
Warm air rises and cooler air moves in.
This causes sea breezes which keep coastal
areas from having the extreme
temperatures.
Mechanical Waves
must travel through a medium such as
solids, liquids, or gases and include sound
waves, water waves, and seismic waves.
Watershed
large areas of land whose rivers and
streams will drain into the same large body
of water
Allele
one part of a pair of forms of a gene. One
allele for a trait comes from the mother and
the other comes from the father.
Transform
plates are sliding past each other
Compaction
process that mashes sediment together into
sedimentary rock
Make your wager
Feedback
Mechanism
a response of an organism to a given
change, such as temperature or amount
of light
