The molecular, cellular, and organismal foundation of biology — the starting point for biology majors and pre-professional students.
BIO 181 introduces students to the structure and function of living things at the molecular, cellular, and organismal levels. The course is designed for biology majors and pre-professional students — particularly those headed for health-profession programs or graduate school — and proceeds at an intentionally intense pace to build the foundation those next steps require.
Field trips may be required at the student's expense. Lab fee required. BIO 181 is the gateway course for the BS Biology major and pairs with BIO 182 General Biology II to form a full two-semester survey of living systems.

Understand Cellular Structure
Examine how living systems are organized at the cellular level.
Apply the Scientific Method
Design experiments, collect data, and interpret results in the lab.
Study Molecular Biology
Engage the molecular basis of life — DNA, proteins, and metabolic processes.
Examine Organismal Function
Connect cellular processes to whole-organism function.
Develop Lab Skills
Build the bench skills required for upper-division biology coursework.
A Biblical Worldview treats living systems as something to be carefully investigated and appreciated — creation worth knowing in detail. BIO 181 builds the scientific literacy that lets students engage biology as both rigorous science and as wonder at how complex life actually is.
