This
exam will cover chapters 1, 15, 19, 20, 22, and 2

Study tips: Study everyday. If you are a
visual person then draw diagrams to explain processes, if you are a reader,
then read the corresponding sections of the text. Find a study partner and have
them teach you the important concepts, then teach them back. Go through your
lecture notes. Do not use this study guide until you have put some time in
studying! While you are studying try to guess what written questions I may ask.
Many topics lend themselves well to written questions as opposed to multiple
choice. Review your quizzes and write your own test!

Chapter 1:
Here we discussed the process of science.

Below is a list of concepts to review:
Ø Define science

Ø Define the science of biology

Ø Know the properties of life

Ø Know
the hierarchical organization of life starting with cell and ending with
population
Ø Be familiar with the 5 themes in biology
that we introduced in this chapter

Ø Be able to describe, while providing an
example, the scientific method

Ø Know the various sections in a scientific
report

Chapter 15

We jumped ahead to this chapter to
continue our discussion of science, biology, life, and move on to discuss the
various ‘’types” of life. Below is a list of concepts to review:
Ø Define biodiversity

Ø Define taxonomy

Ø Describe the Linnaean system and provide
an example

Ø Know
how organisms are categorized: Domain, Kingdom, Phylum, Class, Order, Family,
Genus, Species

Ø Explain
the difference between the biological species concept and the phylogenetic
species concept

Ø Define cladistics

Ø Define Clade

Ø Which of the six kingdoms are eukaryotes

Ø Which of the six kingdoms are prokaryotes

Ø What is the difference between a
eukaryote and prokaryote?

Ø Be able to describe each of the domains

Ø Provide examples of Archaea and know
where they are found

Ø Explain why it is thought that archaea
are more closely related to Eukarya

Ø What is endosymbiosis

Chapter 19: After Chapter 15 we moved on
to Chapter 19 and discussed ecology, populations and communities.

Below is a list of concepts for you to
review:
Ø Define ecology

Ø Explain the 6 levels of ecological
organization

Ø Name the three patterns that populations
can be dispersed

Ø Describe with an example exponential and
logistic population growth

Ø Describe how a population grows along a
sigmoid growth curve

Ø Explain two density-dependent effects on
population growth

Ø Explain two density-independent effects
on population growth

Ø Compare r-selected and K-selected species

Ø Define cohort

Ø Provide explanations for each of the
three survivorship curves

Ø Compare aposematic and cryptic coloration

Ø Describe the three types of mimicry that
we discussed in class

Ø Understand
population demographics such as sex ratio, age distribution, and explain why it
is important to collect such data on populations
Ø Define fecundity and mortality

Ø Define community

Ø Explain interspecific and intraspecific
competition

Ø Explain the difference between realized
and fundamental niche

Ø What is the principle of competitive
exclusion

Ø What is resource partitioning, and what
causes it?

Ø What is the difference between sympatric
species and allopatric species

Ø Explain character displacement

Ø Explain mutualism, parasitism and
commensalism

Ø Understand predator prey cycles

Ø Provide examples of plant and animal
defenses

Ø Define the difference
between primary and secondary succession

Chapter 20

Be familiar with the following concepts:

Ø Define ecosystem

Ø Define primary productivity, net primary
productivity and biomass

Ø Provide examples of each of the trophic
levels

Ø Understand
how energy is lost as we move up form one trophic level to the next

Ø Explain ecological pyramids

Ø Explain the environmental water cycle and
the organismal water cycle

Ø Explain how clear-cutting disrupts the
water cycle

Ø Explain how carbon cycles through an
ecosystem

Ø Explain how nitrogen cycles through an
ecosystem

Ø Explain how phosphorous cycles through
the ecosystem

Ø Explain eutrophication

Ø Explain
how the earth’s tilt drives air circulation and thus shapes our planet’s biomes

Chapter 22

Ø Explain
why science is cumulative and how this is portrayed in understanding climate
change

Ø Be
able to explain the significant historical findings in understading climate
change:
o
Earths
atmosphere holds heat

oAtmospheric gases are N, O, H2O, CO2, and O3
oCO2, H2O, and O3 hold in
infrared heat

o
An increase or decrease
in CO2 will cause a warming or cooling in theearths surface respectively

o
Human activity is adding
CO2 to the atmosphere and changing the‘transparency’

o
There are daily
and annual cycles of CO2
Ø Describe the scientific evidence behind
climate change

Ø What causes the ozone hole?

Ø Name three human practices that are
responsible for biodiversity loss

Ø Explain the importance of habitat
restoration

Ø Define keystone species

Chapter 2: We
then switched gears and began to explore biology at the smallest level. In this
chapter we covered atoms, isotopes, molecules, bonds, properties of water, and
pH. Be sure to study the following:
Ø The structure of an atom (protons,
neutrons, electrons)

Ø What is the atomic number of an atom?

Ø What is the mass number of an atom?

Ø Organization of electrons (shells and
orbitals)

Ø Define ions and isotopes

Ø Define molecule

Ø Describe the three bonds that form
molecules (ionic, covalent, hydrogen)

Ø Define electronegativity

Ø Be able to explain two properties of
water and their importance to life

Ø Define hydrophilic and hydrophobic

Ø How is pH measured (concentration of H+)

Ø What pH is acidic? Basic? Neutral?

Ø What is a buffer?
