STATION 1: Cell Division (Ch. 8.2, 8.3, and 10.2)

 

  1. What is the cell cycle?

 

  1. What are the parts/phases of the cell cycle?  What happens during each part (briefly)?

 

  1. When does a cell go through mitosis/what is mitosis used for?

 

  1. Describe the cells that are produced by mitosis (number, amount of DNA, identical or not).

 

  1. How is the cell cycle regulated?

 

  1. What happens when the cell cycle is NOT regulated?

 

  1. What is meiosis?

 

  1. Where does meiosis take place?

 

  1. What kinds of cells does meiosis produce (specific name!)?  What is meiosis used for?

 

  1. Describe the cells that are produced by meiosis (number, amount of DNA, identical or not). 

 

  1. How are segregation and nondisjunction related?  What kinds of problems can occur if nondisjunction takes place?

 


 

Station 2: Heredity (10.1, 12.1, 12.2)

 

  1. Make sure you know what the following words mean (and that you can USE them!): dominant, recessive, phenotype, genotype, punnett square, heterozygous, homozygous, monohybrid, dihybrid

 

  1. Draw a punnett square to show the cross between someone who is AA and someone who is aa.  What is the likelihood that I will get any offspring genotypes like either parent? 

 

  1. R is round and r is wrinkled.  Y is yellow and y is green.  Make a punnett square to show the cross between a plant that is heterozygous for both traits, and a plant with the genotype RRYy.  Describe the offspring’s phenotypes.

 

  1. Look at the following pedigree.  Affected individuals are indicated as colored in.

 

 Sample Pedigree 

    1. What is the genotype of individuals I-1 and II-1?
    2. What is the genotype of individual I-2?  How do you know?
    3. What is the genotype of individuals II-2 and II-3?  How do you know?
    4. If individual II-3 married someone who is homozygous recessive, what are the chances that one of their children will also be homozygous recessive?

 


 

Station 3: Evolution (Ch. 15)

 

  1. What THINGS produce genetic variation in a population?

 

  1. Why is genetic variation so important?

 

  1. What is an adaptation?  Give examples.

 

  1. What is natural selection?  Give an example of how it works.

 

  1. Look at the diagram provided at your table.  It shows the evolutionary tree for several species of bears. 

 

    1. Who is the most recent common ancestor for the Asiatic Black bear, the American Black bear, and the Brown bear?  How do you know?
    2. Who is the closest relative of the spectacled bear?
    3. Who is more closely related to the American black bear?  How do you know?

 

 


 

STATION FOUR: ANIMAL BEHAVIOR (Ch.33 and pp. 45-46)

 

  1. Give an example of a courtship behaviors, and describe its ultimate purpose.

 

  1. What are the two types of dormancy seen in animals?  Why do animals go dormant?

 

  1. What are the benefits of animals living in groups?

 

  1. What are territories, and what are the benefits to defending them?

 

  1. What is mutualism?  Give an example.

 

  1. What is parasitism?  Give an example.

 

  1. What is commensalism?  Give an example.

 

  1. What is intraspecific competition?  Give an example.

 

  1. What is interspecific competition? Give an example.

 


 

STATION FIVE: ECOLOGY (Ch.2)

  

  1. Make sure you are comfortable with all of the vocabulary used during this unit: producer, consumer, autotroph, heterotroph, primary consumer, secondary consumer, tertiary consumer, decomposers, food chain, food web, abiotic, biotic, 10% rule, matter cycling
  2. Do the chapter 2 assessment questions 1-20.  If you can answer these, you should be okay.  J  Just make sure that you remember that 10% rule!!
