Answer 1

Welcome to OpenStudy.
Hope this site proves to be very helpful to you.
If lucky, you just might get a response from another OpenStudy user who is familiar with biology. More likely than not, however, you won't.
Not trying to brush you away, you understand, but I think your best bet right now would be to look up both ELODEA and TETRAHYMENA on the Internet and look for mention of the issues that interest you.
Good luck!
