What is Life? - correct answer the condition that distinguishes animals and plants from
inorganic matter, including the capacity for growth, reproduction, functional activity, and
continual change preceding death.
Cell - correct answer The basic unit of structure and function in living things
Organism - correct answer consist of one or more cells
-every cell has outer membrane that separated from its surroundings
atoms - correct answer Building blocks of matter
Molecule - correct answer A group of atoms bonded together
Organelle - correct answer specialized structure that performs important cellular
functions within a eukaryotic cell
Tissues - correct answer Groups of cells with a common structure and function.
organs - correct answer Tissues are organized into:, group of tissues that work together
to perform closely related functions.
organ system - correct answer group of organs that work together to perform a specific
function

given area

physical environment.
, Biosphere - correct answer part of Earth in which life exists including land, water, and
air or atmosphere

upward in the hierarchy of life, owing to the arrangement and interactions of parts as
complexity increases.

state; the regulation of any aspect of body chemistry, such as blood glucose, around a
particular level
asexual reproduction - correct answer Process by which a single parent reproduces by
itself
sexual reproduction - correct answer A reproductive process that involves two parents
that combine their genetic material to produce a new organism, which differs from both
parents
