MITOSIS ON LINE

 

Visit www.biology.arizona.edu and go to the Cell Biology page. There are two things that I want you to do.

 

First, click on “The Cell Cycle and Mitosis” then go to the Mitosis site and read the material comparing it to your notes. You should find 3 new terms, learn these, add them to your notes and also record them in the chart below.

 

Term                                        Meaning

 

 

 

 

 

 

 

 

 

 

 

 

 

Take time to see the animation and to test yourself on the questions 8-11.

 

Next, go back to the Cell Biology page and find the Online Onion Root tip Activity. Here read the information (it should be review) and do the activity. Fill out the table below as you go.

 

 

 You can enter data in this table as you go along, or at the end of the activity.

for it to be the same diameter as the Earth? __________________

 

  1. Look at the picture of the head of a pin, how many times can you click on it to increase its magnification with the SEM (scanning electron

microscope)? __________ Describe what you see as you continue clicking on the picture.

                                                                                                Name __________

GRAVITY

 

At http://www.physicscentral.com/ click on the “from physics in action” and from the archives find “big G”.

 

  1. Read about Newton and fill in the blanks:

 

Newton tested his theory of gravitation with the large masses of _____________________ like the________, ___________, and_________.

 

 

2. Who designed this apparatus? ________________

                   When was it designed? ________

 

                   What does it measure? ________

 

3. Who at the University of Washington developed a different looking apparatus that measures the same thing as in #2?

 

_______________________________________________

 

 

 

4. How accurate is the measurement of “G” by these 2 people? ________

 

5. What is the brand new highest precision mass of the Earth? __________

 

     What else was needed to do this calculation? __________________

 

 

6. Also at the University of Washington gravity is being measured at the submillimeter scale. The force has long been studied over planetary distances but is more difficult to gauge at the terrestrial scale, why is that?

Next, visit Neuroscience for Kids at http://faculty.washington.edu/chudler/neurok.html and explore the cranial nerves at brain basics. Compare your chart to theirs. Learn the order of the 12 nerves by copying down their mnemonic device or make one of your own in the space below.

 

 

 

 

 

Pick 5 cranial nerves to test with a partner and check off the ones you chose.

 

 

 

Back to the innerbody site, check out “In love with chocolate” and “Did you Know” and record here.
