Biology 101 Study guide: Final
This study guide is by no means a standalone study tool nor is it entirely comprehensive. There is no
substitute for attending lectures and studying the material as you go. It is merely a guide
to help you
keep on top of your studies. Exam material comes primarily from lecture and secondarily from the text.
You must be able to read and understand your text to do well on the midterm. The exam will be a
mixture of difficulty levels according to Bloom’s Taxonomy with special emphasis on applying and
