Adaptation - ANSWER-Inherited characteristic of an organism that enhances its survival
and reproduction in a specific environment.
.Atom - ANSWER-Smallest level of any chemical element, Indivisible
.Biology - ANSWER-Study of Life; body of knowledge and an ongoing inquiry process to
enhance it
.Biology take us - ANSWER-1. Variety of environments to investigate ecosystems
2. to the lab to examine how organisms work

with which they interact; one or more communities and the physical environment around
them
.Emergent properties - ANSWER-New properties that arise with each step upward in
the hierarchy of life, owing to the arrangement and interactions of parts as complexity
increases.
.Energy Processing / Metabolize - ANSWER-sum of a chemical reactions anabolism &
catabolism. Takes energy and uses it or releases heat
.Eukaryotic Cell - ANSWER-A type of cell with a membrane-enclosed nucleus and
