Abiotic Ans: Non-living, may be within or made by a living
organism.
Biotic Ans: Living. Matter is considered ______ if it was

ever alive at some point in time
Guru01 - Stuvia
Atom Ans: Smallest level. The basic unit of matter.
Consists of a dense nucleus surrounded by electrons.
Expert
Molecule Ans: Second level. A chemical structure
consisting of at least two atoms held together by a
chemical bond.
Macromolecule Ans: Third level. Biologically important
molecules that are technically polymers. Example: DNA.
Cell Ans: Fourth level. The fundamental unit of life.
Essentially a tiny droplet of water and other molecules
enclosed by a fluid "skin" or membrane. The smallest and
simplest entity that possesses all the characteristics of
life.
Organelle Ans: Fifth level. Compartments inside the cell
that contain specific groups of macromolecules and carry
out specific cellular functions. One of these organelles is
the nucleus; it encloses the DNA within the cell.
, 2
Microorganism Ans: Sixth level. Single-celled life form.
Consists of just one cell and include unicellular organisms
such as bacteria and protists.
Tissue Ans: Seventh level. Formed when similar cells work
together to fulfill the same detailed function.
Organ Ans: Eighth level. Collections of tissues that work
together to carry out a common general function. Present
not only in higher level animals but also in plants.

Organ System Ans: Ninth level. Consists of functionally
Guru01 - Stuvia
related organs. Mammals have many.
Expert
Organism Ans: Tenth Level. Individual living entities that
survive and reproduce as a unit. For example, each tree in
a forest.
Population Ans: Eleventh level. Consists of all the
individuals of a species living within a specific area.
Community Ans: Twelfth level. Populations can interact
with each other in positive and negative ways, and
together they form this.
Ecosystem Ans: Thirteenth level. Consists of all the living
things in a particular area together with the abiotic, or
nonliving, parts of that environment.
Biosphere Ans: Fourteenth level. The highest level of
organization in living systems. The collection of all
ecosystems on Earth. Includes all habitable zones on the
planet, including land, soil, and rocks to a great depth in
, 3
the Earth's crust; water and ice; and the atmosphere to a
great height.
Emergent Properties Ans: Characteristics of a system that
are not present in any of its component parts.
Biology Ans: The scientific study of life and is the branch
of science that studies living organisms and the way
organisms interact with their environments.

Homeostasis Ans: The ability or tendency of organisms
and cells to maintain stable internal conditions.
Guru01 - Stuvia
Expert
Nutrient Ans: Any matter an organism needs but cannot
make for itself.
Energy Ans: The capacity to do work or to make a change
in the location, temperature, or structure of matter. Does
not have mass and it does not take up space, but it can be
measured in terms of what it does.
Growth Ans: An increase in size.
Development Ans: Structure and function change in an
orderly way as an organism passes through its life cycle.
An individual's pattern of _______ is partly determined by
genetic instructions.
Reproduction Ans: Occurs when an individual organism
passes on its genetic information to a newly independent
organism, or offspring.
, 4
Evolution Ans: A scientific theory that explains how and
why life changes over time. Provides the explanation for
why all living organisms share profound similarities, and
yet, the life forms on our planet are so incredibly diverse.
Natural Selection Ans: Individuals are always a bit
different from their parents and from each other, partly
because of changes to their genes. These differences may
be helpful or harmful to the individuals that inherit them.
In nature, individuals often have very low odds of

surviving to reproduce. Individuals with slightly harmful
or even average characteristics might be less likely to
make it, and those with traits that fit in very well with the
Guru01 - Stuvia
local habitat will have the greatest chance to survive and
Expert
reproduce. This sorting process goes on generation after
generation.
Atomic Mass Ans: The sum of the number of protons and
the number of neutrons. The mass of an atom.
Atomic Number Ans: The number of protons in an atom,
displayed for each atom in the periodic table.
Chemical Bonds Ans: Attractions between atoms that hold
atoms and molecules together.
Covalent Bonds Ans: Strongest chemical bond. Occurs
between atoms of in the same molecule. Electron pairs are
shared, creating a strong bond between atoms.
electron Ans: Subatomic particle, located in shells on the
outside of the nucleus, has a negative charge and almost
no mass.
