BI 105 - Perspectives in Biology


BI 105: Perspectives in Biology (5). Lec. 4, Lab 2.
All quarters. Principles of biology with emphasis on the relationship between man and modern biological science. Broad topics include cell biology, inheritance, evolution, and introduction to ecology. This course is designed specifically for the student satisfying a general education requirement in natural science. Cannot be used to meet major or minor requirements in biological science. Credit will not be allowed for both BI 101 and BI 105 or SM 101.

Prerequisite: None

Evaluation
Evaluation of student performance is based on cumulative scores of a 500-point total with three major lecture tests @ 100 pts each; laboratory participation (27 pts), lab practical exam (40 pts); the comprehensive final exam (100 pts) and written lab final (33 pts); with 15 possible extra points earned from small lecture quizzes. Final grades are determined on a 10% scale (90-100% or 450 - 500 points earns an A, etc.)
