Question 1
Abiotic
Correct Answer
Non-living, may be within or made by a living organism.
Question 2
Biotic
Correct Answer
Living. Matter is considered ______ if it was ever alive at some point in time
Question 3
Atom
Correct Answer
Smallest level. The basic unit of matter. Consists of a dense nucleus surrounded by electrons.
Question 4
Molecule
Correct Answer
Second level. A chemical structure consisting of at least two atoms held together by a chemical bond.

,Question 6
Cell
Correct Answer
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.
Question 7
Organelle
Correct Answer
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.
Question 8
Microorganism
Correct Answer
Sixth level. Single-celled life form. Consists of just one cell and include unicellular organisms such as bacteria and protists.
Question 9
Tissue
Correct Answer
Seventh level. Formed when similar cells work together to fulfill the same detailed function.
Question 10
Organ
Correct Answer
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.
Question 11
Organ System
Correct Answer
Ninth level. Consists of functionally related organs. Mammals have many.
Question 12
Organism
Correct Answer
Tenth Level. Individual living entities that survive and reproduce as a unit. For example, each tree in a forest.

,Question 13
Population
Correct Answer
Eleventh level. Consists of all the individuals of a species living within a specific area.
Question 14
Community
Correct Answer
Twelfth level. Populations can interact with each other in positive and negative ways, and together they form this.
Question 15
Ecosystem
Correct Answer
Thirteenth level. Consists of all the living things in a particular area together with the abiotic, or nonliving, parts of that
environment.
Question 16
Biosphere
Correct Answer
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 the Earth's crust; water and ice; and the
atmosphere to a great height.
Question 17
Emergent Properties
Correct Answer
Characteristics of a system that are not present in any of its component parts.
Question 18
Biology
Correct Answer
The scientific study of life and is the branch of science that studies living organisms and the way organisms interact with
their environments.
Question 19
Homeostasis
Correct Answer
The ability or tendency of organisms and cells to maintain stable internal conditions.

, Question 20
Nutrient
Correct Answer
Any matter an organism needs but cannot make for itself.
Question 21
Energy
Correct Answer
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.
Question 22
Growth
Correct Answer
An increase in size.
Question 23
Development
Correct Answer
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.
Question 24
Reproduction
Correct Answer
Occurs when an individual organism passes on its genetic information to a newly independent organism, or offspring.
Question 25
Evolution
Correct Answer
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.
Question 26
Natural Selection
Correct Answer
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 local habitat will have the greatest chance to survive and
reproduce. This sorting process goes on generation after generation.
