Test #3 Study Guide

In this space, we will be collaboratively creating the study guide for the upcoming test over Topics 5 and 6. Each student in the class is expected to post at least one question to the study guide.

Global Climate Change

  1. How does the process of global warming occur? What role do humans play in global warming?
  2. What is the name of the greenhouse gas we are most concerned about?
  3. Be able to draw a Revelle/Keeling Curve.
  4. Describe the relationship between temperature and atmospheric CO2 concentration over the last 650,000 years.
  5. What will happen if the Antarctica land base ice start to melt?
  6. Explain the relationship between increased hurricane incidence and global warming.
  7. How do humans play a role in speeding up global warming and then what can we do to slow the rate down?
  8. How are ice cores used to study past climate changes and explain what exactly they are measuring in the ice cores.
  9. How does global warming have an effect on the Earth's rainfall and fresh water systems?
  10. Provide examples of how the life on Earth has begun changing in response to global climate change.


What makes us so similar, what makes us so different?

  1. List the four macromolecules needed for life.
  2. Explain why each macromolecule is important and describe the most important function of each group.
  3. List the four factors we used to define the term "life".
  4. Compare and contrast the concepts of prokaryotic and eukaryotic cells.
  5. Describe the internal structure of typical prokaryotic and eukaryotic cells.
  6. If a cell lacks ribosomes, can it be alive?
  7. Define the following terms:
    1. Genotype
    2. Phenotype
    3. Dominant
    4. Recessive
    5. Purebred
    6. Hybrid
    7. Heterozygous
    8. Homozygous
    9. Chromosome
    10. Gene
    11. Allele
    12. Gamete
  8. Make a Punnett square for the following traits: PP X Pp. Assume strict Mendelian inheritance (i.e., clear dominant and recessive traits).
    1. Determine the genotypes in the possible offspring, along with probabilities.
    2. Determine the phenotypes in the possible offspring, along with probabilities.
  9. What are Mendel's two laws of heredity?
  10. What happens during interphase?
  11. What are the phases of Mitosis?
  12. Why is it important for mitosis to be "boring"?
    1. What happens when mitosis is not boring? Briefly describe.
  13. What is Meiosis? What role does meiosis play in sexual reproduction?
  14. How does meiosis create variation/variability within a species?
  15. Answer the following cell reproduction & meiosis questions in the context of human cells.
    1. A gamete need(s) ____ copy/copies of each chromosome.
    2. New cells (non-gamete) need(s) ______ copy/copies of each chromosome.
  16. What is natural selection? Describe the three modes of natural selection (directional, stabilizing, diversifying)
  17. What is Genetic Drift and how does it have to relate to Natural Selection?
  18. Define the term "population'"
  19. Describe how the genetic variability within a population serves as the raw material for evolution.
  20. What is believed to be the oldest cell type, and what is significant about this?
  21. What are the 3 domains of life? Which domain do we as humans belong to? What other subgroups are in our domain?
  22. Describe the Endosymbiotic Theory.
  23. What evidence supports this endosymbiotic theory?
  24. List and describe the three domains of life.
