, Biologists Answer: study how humans and other living organisms interact with their
environment.
Biology Answer: is the scientific study of life and is the branch of science that studies living
organisms and the way organisms interact with their environments.
To be considered alive, something must be made up of 5 distinct qualities: Answer: -Be made
of materials organized in a hierarchical pattern.
-Use energy and raw materials to survive.
-Sense and respond to changing environments and maintain internal stability, or homeostasis.
-Grow, develop, and reproduce.
-Be part of a population that evolves.
cell Answer: smallest living organism that shows all 5 characteristics of life
Matter Answer: any substance that has mass and takes up space.
All matter can be classified in one of two categories: Answer: biotic (living or having lived) or
abiotic (nonliving and never having been alive).
biotic Answer: living or having lived
abiotic Answer: nonliving and never having been alive
Atom Answer: basic unit of matter
molecule Answer: a chemical structure consisting of at least two atoms held together by a
chemical bond
Macromolecules Answer: biologically important molecules that are technically polymers
When macromolecules are used as building blocks to form a membrane-bound sphere Answer:
you have a cell
two main types of cells Answer: prokaryotes and eukaryotes
prokaryotes Answer: small and simple; they do not have any clearly defined compartments
inside of them
eukaryotes Answer: include membrane-bound organelles
organelles Answer: compartments inside the cell that contain specific groups of
macromolecules and carry out specific cellular functions
microorganisms Answer: Single-celled life forms
Tissues Answer: formed when similar cells work together to fulfill the same detailed function
