Daily Bio Activities

  • 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?

  • Whale Evolution and Classification

    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?
