Biology help

[xcalibur]

I need help with the biotechnology chapter as well as ecology.
Biotechnology especially the fermenter and the things required for it... and in ecology the whole thing is really weird to me.
If anyone has any notes or can suggest the best place to prepare for these topics i would really appreciate it!
