common? - ANSWER -
DNA
What do biologists mean when they use the term
"HOMEOSTASIS"? - ANSWER -HOMEOSTASIS is maintaining a
constant regulated INTERNAL environment of all living things
What is the "standard" definition for EVOLUTION? -
ANSWER -Evolution is
GENETIC CHANGE in a ECOLOGICAL population
through time
What is a BIOGEOCHEMICAL CYCLE? How do they link
organisms together? -
ANSWER -A biogeochemical cycle is a predictable pattern in
which matter is
constantly being shuffled in the atmosphere
(RECYCLING)
,As these cycles
occur,
atoms Move in and out of organisms and link
them together
What is an ELEMENT? How is one specific element different
from any other
element? - ANSWER -An element is a UNIQUE type of atom
with a specific
number of
protons
AND
a UNIQUE set of physical
characteristics
