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?

Whale Evolution and Classification

posted Jan 7, 2019, 9:29 AM by Jerrid Johansen   [ 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?

Planet or Plastic?

posted Sep 17, 2018, 1:09 PM by Jerrid Johansen

I don't even know where to begin with this topic?  The numbers are staggering.  The pictures are disturbing.  And all of it makes me upset.

Spend some time exploring the National Geographic Series, PLANET OR PLASTICStudy the pictures.  Read the captions.  Check out the infographics and data tables.  Watch the short videos.  Get a sense of the magnitude of the problem.

Some things to consider:
  • What is plastic, and what's its history?
  • What are the quantities being described in these links?
  • How much is produced?  Recycled? 
  • How much ends up in landfills?  How much ends up in our waterways?
  • What are the problems associated with plastic pollution?
  • What are the challenges in dealing with plastic pollution?
  • Who is responsible for dealing with this problem?
  • What are the solutions?
