Textbook:            Life on Earth by Audesirk, Audesirk & Byers

 

 

Course Description: This is an introductory course for students majoring in an area other than science. The course material is presented within the context of the human experience and covers cell biology, physiology, genetics, evolution, ecology and the interaction of humankind with the environment. The success of this course depends on both of us - me, by providing the opportunity for your involvement, and you, by your active participation in the process.

 

Class Attendance: Attendance is a matter of individual choice in this class. However, a strong association exists between attendance and grades. Students who miss regularly rarely do well in the course. There will be unannounced quizzes and assignments given with no make-ups, so it is in your best interest to attend class.

 

Examinations: There will be 4 regular multiple choice and short essay exams each worth 100 points, and several unannounced quizzes and assignments covering lectures and readings. Exams will cover information presented in lecture and assigned readings. The final course grade will be determined by the percentage of points out of the total. There will be no cumulative final.

 

Honor Code: Follow it. Those caught cheating on exams, improperly referencing published written or electronic material, or submitting work that is not your own will fail the course.

 

 

 

SYLLABUS

 

 

Part I - Energy Flow - Why does life exist on Earth?....How did life evolve?.....Are viruses alive?....How did complex cells evolve?...The dynamic cell - how does it do what it does?....What is the ultimate source of all biological  energy?...How is chemical energy used to do biological work?
