Students will turn in weekly problem set and TAs will go over the answers.Class Website• http://www.bio.unc.edu/Courses/2010Spring/Biol205-006/• Lecture notes will be posted the day before the lecture (.PDFfile)• Problem sets will be posted on Friday afternoon and will be due the following week in recitationRequired Textbooks• Essential Cell Biology, 3rd edition, by Alberts et al. (first half of the course) • Principles of Development, 2nd edition, by Wolpert (second half of the course)Grading Policies• 4 non-cumulative exams count towards 92% of the final grade. Weekly problem sets count towards 8% of final grade.• Tests will cover information in lectures, recitations, and reading assignments• Make-up exams will be given only for valid reasons (medical excuses)• Regrade requests must be submitted prior to the next examPolicies• UNC-CH honor code. All exams are to be taken without books notes, or other people and you will be asked to sign a pledge to that effect.• Please turn off your cell phones during classAdvising for Biology Majors• • Degree Programs • Biology General Education Requirements • Bachelor of Arts in Biology • Bachelor of Science in Biology • Minor in Biology • Advising-How to find a Biology adviser• Undergraduate Advising • Abbey Fellow-Dr. Elaine Yeh [email protected] • Resources• Biology Majors' Manual• Study Abroad • Registrar's Online Services • • Research Opportunities • Undergraduate Research • Biology Honors Program Funding & Outreach • Office of Undergraduate Research • Please go to the Biology Department websitehttp://www.bio.unc.edu/Undergraduate/ to find information about:What is cell Biology?What is cell Biology?Divisions in the biological sciences are based on degrees of “complexity”Biochemistry & Biophysics: study of the structures and behaviors of moleculesMicrobiology: study of prokaryotic cells and virusesCell Biology: study of the structure and function of eukaryotic cellsDevelopmental Biology: study of how communities of cells form tissues, organs, and build an organismAnatomy & Physiology: study of the structures and functions of tissues and organsZoology & Plant Biology: study of the organismsEcology: study of how organisms interact with each other and with their environmentsLevels of Biological Complexity1.
