BIOS101 General Biology Exam #1 Test Bank

[Pages:6]BIOS101 General Biology Exam #1 Test Bank

This test bank covers the scientific study of life, the chemical basis of life, the molecules of cells, the origin of life and a tour of the cell. This material is the first section that I teach in BIOS 101. The text book used is the 5th edition of Biology: Concepts and Connections edited by Campbell and Reese. When teaching this course I try to give the students a general understanding of the material that they can then use to build upon in future courses. These questions reflect a portion of that intent.
