WGUC190 Introduction to Biology Module Exam Questions and
Answers with Verified Solutions | Latest 2026 Update
Q: Non-living, may be within or made by a living organism.
Answer:
Abiotic
Q: Living. Matter is considered if it was ever alive at some point in time
Answer:
Biotic
Q: Smallest level. The basic unit of matter. Consists of a dense nucleus
surrounded by electrons.
Answer:
Atom
Q: Second level. A chemical structure consisting of at least two atoms held
together by a chemical bond.
Answer:
Molecule
Q: Third level. Biologically important molecules that are technically polymers.
Example: DNA.
Answer:
Macromolecule
Q: 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.
Answer:
Cell
Q: 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.
,Answer:
Organelle
Q: Sixth level. Single-celled life form. Consists of just one cell and include
unicellular organisms such as bacteria and protists.
Answer:
Microorganism
Q: Seventh level. Formed when similar cells work together to fulfill the same
detailed function.
Answer:
Tissue
Q: 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.
Answer:
Organ
Q: Ninth level. Consists of functionally related organs. Mammals have many.
Answer:
Organ System
Q: Tenth Level. Individual living entities that survive and reproduce as a unit.
For example, each tree in a forest.
Answer:
Organism
Q: Eleventh level. Consists of all the individuals of a species living within a
specific area.
Answer:
Population
Q: Twelfth level. Populations can interact with each other in positive and
negative ways, and together they form this.
Answer:
Community
,Q: Thirteenth level. Consists of all the living things in a particular area together
with the abiotic, or nonliving, parts of that environment.
Answer:
Ecosystem
Q: 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.
Answer:
Biosphere
Q: Characteristics of a system that are not present in any of its component parts.
Answer:
Emergent Properties
Q: The scientific study of life and is the branch of science that studies living
organisms and the way organisms interact with their environments.
Answer:
Biology
Q: The ability or tendency of organisms and cells to maintain stable internal
conditions.
Answer:
Homeostasis
Q: Any matter an organism needs but cannot make for itself.
Answer:
Nutrient
Q: 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.
Answer:
Energy
, Q: An increase in size.
Answer:
Growth
Q: 0 0 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.
Answer:
Development
Q: Occurs when an individual organism passes on its genetic information to a
newly independent organism, or offspring.
Answer:
Reproduction
Q: 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.
Answer:
Evolution
Q: 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.
Answer:
Natural Selection
Q: The sum of the number of protons and the number of neutrons. The mass of
an atom.
Answer:
Atomic Mass
