Exam 1 Review

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?
