I am a 13-year-old student with an ambitious science fair project and I've
got a problem.  In my science fair project I'm trying to see if a certain
substance can be harmful to fruit flies.  To determine that the substance
did clog the spiricals, I had to do histological sectioning.  After
looking at the slides and taking pictures, I ran into the problem of
determining if the tubular structures I was seeing underneath the
microscope were spiricals or intestines. How can I tell the difference
between the two.  I would also appreciate any information on how to get
oriented with the body of the fruit fly under the microscope.  Thank you
very much for any help you could provide.
