Here are some online resources for the Unit 6 (Meiosis) Test, which will be on Tuesday, March 5th:

Snurfle Meiosis

Go to the SNURFLE MEIOSIS website and complete the Meiosis Interactive and the Chromosome Quandary.

From the Meiosis Interactive:
  1. Why do organisms perform MEIOSIS?
  2. MEIOSIS is all about the chromosomes, and I summarize the process by saying "Double, Split, Split."  Why is that a good summary for what happens to the chromosomes during MEIOSIS?
  3. How does MEIOSIS solve the Funny Math Problem? (46+46=46)
From the Chromosome Quandary 
  1. When it comes to naming chromosomes, how did scientists really screw things up?
  2. Distinguish between a chromosome and sister chromatid.  
  3. When does a chromatid become a chromosome?

Check out these articles on two controversial uses of the CRISPR Cas9 gene editing system, and be ready to discus the, "WHO, WHAT, WHERE, WHEN, WHY, and HOW?" of the articles.

Whale Evolution and Classification

posted Jan 7, 2019, 9:29 AM by South Titan Track & Field   [ updated Jan 10, 2019, 1:05 PM ]


Let's dissect this cartoon a little bit.  What's accurate?  What's inaccurate?  Why is the whale walking?  And why is it walking back into the water?

With that as a backdrop, let's do a little classifying of whales.  Create a traditional classification diagram for the following organisms.  Use these IMAGES to help you with the classification.

Go to the UNIPROT website.  Do an HBA ALPHA search for the following animals:


Align the 12 organisms and study the family tree that is produced.  What is closely related to the whales?  What does that mean for the evolution of the whales?  What evidence would we see if this relationship is true?


Using Anatomy to Understand Evolution

Go to UNDERSTANDING EVOLUTION, and complete the module over Homologies and Analogies.
  1. When we discuss analogies in evolution, we are really talking about convergent evolution.  Explain.
  2. What are homologous structures?  Give two examples from the module.
  3. What are analogous structures?  Give two examples from the module.
  4. Why are homologies solid evidence for evolution?
Check out the link on HUMAN VESTIGES.
  1. What are vestiges, or vestigial structures?
  2. What are two examples of vestiges in humans?
  3. Why are vestigial structures solid evidence for evolution?

Read the article about different types of medications, and on How Antibiotics WorkThen answer the following questions:
  1. How are antibiotics different than the other 4 medications described at the beginning of the reading?
  2. What are the 3 types of antibiotics mentioned in the reading?
  3. How do the different types of antibiotics work?

Watch this video on Carbon Dioxide Concentration in the Atmosphere, then answer the questions below.

Carbon Dioxide Pump Handle


  1. What do you observe happening in the animation?
  2. Why is it called "The Pump Handle"?
  3. Why does one side of the graph move more "aggressively" than the other?
  4. Why is the graph climbing up?
  5. What does the data from the past tell us about CO2 in the atmosphere?
  6. What questions do you have about the animation, or the data?
