3rd 6 weeks If you like extra credit on your tests, yes. If you have something else you need to be doing, no. Every question correct and stickered will be worth ½ a point on your unit test. I will do this every day at the beginning of class. Scientists determined that organisms of the genus Spinoloricus were eukaryotes and not prokaryotes because Spinoloricus cells have — A. B. C.
