WGU C190 INTRO TO BIOLOGY EXAMS WITH
CORRECT SOLUTIONS
1. Macromolecule - ANS☑☑---Third level. Biologically important molecules that
are technically polymers. Example: DNA.
2. 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.
3. 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.
4. Microorganism - ANS☑☑---Sixth level. Single-celled life form. Consists of
just one cell and include unicellular organisms such as bacteria and protists.
5. Tissue - ANS☑☑---Seventh level. Formed when similar cells work together
to fulfill the same detailed function.
6. Abiotic - ANS☑☑---Non-living, may be within or made by a living organism.
7. Biotic - ANS☑☑---Living. Matter is considered ______ if it was ever alive at
some point in time
8. Atom - ANS☑☑---Smallest level. The basic unit of matter. Consists of a
dense nucleus surrounded by electrons.
,Molecule - ANS☑☑---Second level. A chemical structure consisting of at least two
atoms held together by a chemical bond
9. 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.
10. Organ System - ANS☑☑---Ninth level. Consists of functionally related
organs. Mammals have many.
11. Organism - ANS☑☑---Tenth Level. Individual living entities that survive and
reproduce as a unit. For example, each tree in a forest.
12. Population - ANS☑☑---Eleventh level. Consists of all the individuals of a
species living within a specific area.
13. Community - ANS☑☑---Twelfth level. Populations can interact with each
other in positive and negative ways, and together they form this.
14. Ecosystem - ANS☑☑---Thirteenth level. Consists of all the living things in a
particular area together with the abiotic, or nonliving, parts of that environment.
15. 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 the
Earth's crust; water and ice; and the atmosphere to a great height.
,16. Emergent Properties - ANS☑☑---Characteristics of a system that are not
present in any of its component parts.
17. 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.
18. Homeostasis - ANS☑☑---The ability or tendency of organisms and cells to
maintain stable internal conditions.
19. Nutrient - ANS☑☑---Any matter an organism needs but cannot make for
itself.
20. 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.
21. Growth - ANS☑☑---An increase in size.
22. 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.
23. Reproduction - ANS☑☑---Occurs when an individual organism passes on its
genetic information to a newly independent organism, or offspring.
24. 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.
, 25. 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 local habitat
will have the greatest chance to survive and reproduce. This sorting process
goes on generation after generation.
26. Atomic Mass - ANS☑☑---The sum of the number of protons and the number
of neutrons. The mass of an atom.
27. Atomic Number - ANS☑☑---The number of protons in an atom, displayed for
each atom in the periodic table.
28. Chemical Bonds - ANS☑☑---Attractions between atoms that hold atoms and
molecules together.
29. Covalent Bonds - ANS☑☑---Strongest chemical bond. Occurs between
atoms of in the same molecule. Electron pairs are shared, creating a strong
bond between atoms.
30. electron - ANS☑☑---Subatomic particle, located in shells on the outside of
the nucleus, has a negative charge and almost no mass.
31. electronegativity - ANS☑☑---A measure of the tendency of an atom to
attract a bonding pair of electrons. How strongly does an atoms attract bonding
electrons to itself?
