BIO 201 Chapters 1-4 Question and
answers verified to pass 2025
Atom - correct answer ✔(physics and chemistry) the smallest component of
an element having the chemical properties of the element
Molecule - correct answer ✔(physics and chemistry) the simplest structural
unit of an element or compound
Macromolecule - correct answer ✔A giant molecule formed by the joining of
smaller molecules, usually by a condensation reaction. Polysaccharides,
proteins, and nucleic acids are macromolecules.
Cell - correct answer ✔(biology) the basic structural and functional unit of all
organisms
Tissue - correct answer ✔a part of an organism consisting of an aggregate of
cells having a similar structure and function
Organ - correct answer ✔composed of two or more types of tissue
Organisms - correct answer ✔all living things
Population - correct answer ✔a group of organisms of the same species
populating a given area
Community - correct answer ✔assemblage of populations of different
species
, Ecosystem - correct answer ✔a system formed by the interaction of a
community of organisms with their physical environment
Biosphere - correct answer ✔the regions of the surface and atmosphere of
the Earth (or other planet) where living organisms exist
Evolutionary change - correct answer ✔The change in the genetic make-up
of a population that occurs over generations. May result from natural
selection, random genetic drift, etc.
Prokaryotes - correct answer ✔single-celled organisms that do not have a
membrane-bound nucleus
Eukaryotes - correct answer ✔organisms made up of one or more cells that
have a nucleus and membrane-bound organelles
Domains of life - correct answer ✔archaea & bacteria, which have
prokaryotic cells, and eukarya, composed of eukaryotic cells and divided into
animals, plants, protists, & fungi
Bacteria - correct answer ✔single-celled organisms that lack a nucleus;
prokaryotes
Archae - correct answer ✔domain of prokaryotic organisms that are
biochemically and genetically distinct from bacteria
Eukarya - correct answer ✔Domain of all organisms whose cells have nuclei,
including protists, plants, fungi, and animals
