Hi.  My name's Gianna (I'm using my brother's account.) and I have to 
write a report for biology class.  I would appreciate some help answering 
the following:

Who invented the pH scale?
Why should living systems use buffers as a part of their normal 
compositon?
What are stable internal and external enviroments?
Would buffers aid or hinder the maintence of a stable internal enviroment 
in a changing external enviroment?
What occurrances might case a change in the internal chemistry of an 
organism (such as a human)?  What happens?

Post the responses or email to gianna@phsbbs.princeton.nj.us
If the mail bounces try tony@phsbbs.princeton.nj.us
