UPDATED ACTUAL Exam Questions and
CORRECT Answers
Biologists - CORRECT ANSWER - study how humans and other living organisms interact
with their environment.
Biology - CORRECT 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: - CORRECT
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 - CORRECT ANSWER - smallest living organism that shows all 5 characteristics of
life
Matter - CORRECT ANSWER - any substance that has mass and takes up space.
All matter can be classified in one of two categories: - CORRECT ANSWER - biotic
(living or having lived) or abiotic (nonliving and never having been alive).
biotic - CORRECT ANSWER - living or having lived
abiotic - CORRECT ANSWER - nonliving and never having been alive
,Atom - CORRECT ANSWER - basic unit of matter
molecule - CORRECT ANSWER - a chemical structure consisting of at least two atoms
held together by a chemical bond
Macromolecules - CORRECT ANSWER - biologically important molecules that are
technically polymers
When macromolecules are used as building blocks to form a membrane-bound sphere -
CORRECT ANSWER - you have a cell
two main types of cells - CORRECT ANSWER - prokaryotes and eukaryotes
prokaryotes - CORRECT ANSWER - small and simple; they do not have any clearly
defined compartments inside of them
eukaryotes - CORRECT ANSWER - include membrane-bound organelles
organelles - CORRECT ANSWER - compartments inside the cell that contain specific
groups of macromolecules and carry out specific cellular functions
microorganisms - CORRECT ANSWER - Single-celled life forms
Tissues - CORRECT ANSWER - formed when similar cells work together to fulfill the
same detailed function
Organs - CORRECT ANSWER - collections of tissues that work together to carry out a
common general function
,organ system - CORRECT ANSWER - a higher level of organization that consists of
functionally related organs
Organisms - CORRECT ANSWER - individual living entities that survive and reproduce
as a unit
population - CORRECT ANSWER - consists of all the individuals of a species living
within a specific area
populations can interact with each other in positive and negative ways, and together they form a -
CORRECT ANSWER - community
ecosystem - CORRECT ANSWER - consists of all the living things in a particular area
together with the abiotic, or nonliving, parts of that environment
biosphere - CORRECT ANSWER - the collection of all ecosystems on Earth
emergent properties - CORRECT ANSWER - characteristics of a system that do not
appear in any one of its component parts alone, but that appear when all parts are combined.
Biome - CORRECT ANSWER - Areas of the earth with similar characteristics of living
and nonliving things
What is the first level of organization that is alive? - CORRECT ANSWER - The cell
Levels of organization from smallest to largest (simple to complex): - CORRECT
ANSWER - (1) atom
(2) molecule
(3) organelles
(4) cell
, (5) tissue
(6) organs
(7) organ system
(8) organisms
(9) population
(10) community
(11) ecosystem (w/biomes)
(12) biosphere
Process organisms have developed and changed from earlier forms due to mutations and
adaptations - CORRECT ANSWER - Evolution: ancestry and/or adaptation by natural
selection
Ordered parts of biological system - CORRECT ANSWER - Organization
Stable internal environment - CORRECT ANSWER - Response to stimuli and
homeostasis
Making of new organisms and increase in size once produced - CORRECT ANSWER -
Growth and reproduction
Living organisms maintain - CORRECT ANSWER - homeostasis
Energy flows through - CORRECT ANSWER - living systems
matter is - CORRECT ANSWER - recycled
