Q: Biologists
Answer:
study how humans and other living organisms interact with their environment.
Q: 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.
Q: 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.
Q: cell
Answer:
smallest living organism that shows all 5 characteristics of life
Q: Matter
Answer:
any substance that has mass and takes up space.
Q: All matter can be classified in one of two categories:
Answer:
biotic (living or having lived) or abiotic (nonliving and never having been alive).
Q: biotic
Answer:
living or having lived
,Q: abiotic
Answer:
nonliving and never having been alive
Q: Atom
Answer:
basic unit of matter
Q: molecule
Answer:
a chemical structure consisting of at least two atoms held together by a chemical
bond
Q: Macromolecules
Answer:
biologically important molecules that are technically polymers
Q: When macromolecules are used as building blocks to form a
membrane-bound sphere
Answer:
you have a cell
Q: two main types of cells
Answer:
prokaryotes and eukaryotes
Q: prokaryotes
Answer:
small and simple; they do not have any clearly defined compartments inside of
them
Q: eukaryotes
Answer:
include membrane-bound organelles
Q: organelles
,Answer:
compartments inside the cell that contain specific groups of macromolecules and
carry out specific cellular functions
Q: microorganisms
Answer:
Single-celled life forms
Q: Tissues
Answer:
formed when similar cells work together to fulfill the same detailed function
Q: Organs
Answer:
collections of tissues that work together to carry out a common general function
Q: organ system
Answer:
a higher level of organization that consists of functionally related organs
Q: Organisms
Answer:
individual living entities that survive and reproduce as a unit
Q: population
Answer:
consists of all the individuals of a species living within a specific area
Q: populations can interact with each other in positive and negative ways, and
together they form a
Answer:
community
Q: ecosystem
Answer:
consists of all the living things in a particular area together with the abiotic, or
nonliving, parts of that environment
, Q: biosphere
Answer:
the collection of all ecosystems on Earth
Q: emergent properties
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.
Q: Biome
Answer:
Areas of the earth with similar characteristics of living and nonliving things
Q: What is the first level of organization that is alive?
Answer:
The cell
Q: Levels of organization from smallest to largest (simple to complex):
Answer:
(1) atom
molecule
organelles
cell
tissue
organs
organ system
organisms
population
community
ecosystem (w/biomes)

Q: Process organisms have developed and changed from earlier forms due to
mutations and adaptations
