Help with biology question
Basically we did an experiment where there was a tube (without bungs), a ball of cotton wool was dipped into a solution of ammonium hydroxide and placed in one end of the tube. Along the tube was litmus paper and we had to watch as the ammonia made it change colour.
I have to know how this model is similar to mass flow in a transport system such as the mammalian circulatory system.
Any help will be greaty appreciated.
