Practice test for The Biological Perspective.

Note: These questions are part of a larger data base of questions & are selected 
to represent the type of question you should expect on exams. Exam questions, 
however, may deal with topics not covered in the practice tests or in lectures but are discussed in 
your textbook. You are responsible for the content of your text book plus the content of 
lectures, interactive activities, & material on the web site.

Use these sample questions to test yourself & to practice for the test.
