Read chapter 4 and 5 and follow the instructions:
You can earn 5 points of extra-credit on this exam by contributing to the Twitter Study Guide.
You must submit 2 one sentence statements (150 characters maximum) about points you think are important to know for the exam from each chapter. It can not just be copied out of the book but must be in your own words. It also can not just be a definition or a duplication of a previously posted point.
Just to clarify, they must be points of knowledge, not something like, “It is important to know the levels of taxonomic organization.” Instead you should say, “The levels of taxonomic classification, from highest to lowest are, Kingdom, Phylum, Class, Order, Family, Genus, Species.”
You must have your submission completed by midnight of the Thursday prior to the exam.
This is an all or nothing assignment, you either get all of the extra-credit by doing the entire assignment correctly or you get zero points.
