Dear students,

 

Happy New Year!

 

Unit 6 is one of my favorite topics in biology as a result of being a microbiology student of Dr. George Beran at Silliman University.  His degree was in veterinary medicine. A highlight of his career was when he became a World Health Organization director, authored several books and papers and wrote the book Zoonoses. 

 

I am also fascinated by new evidence found in ribosomal and transfer RNA showing Protists should be part of the Domain Euakarya.  In these chapters you should be able to describe diversity through nutrition, cell complexity, and locomotion.  You need to be able to differentiate reproductive mechanisms, characterize representative organisms; understand their ecological roles and economic importance.
