What is Biology?

Biology is the study of life.

Biologists study living organisms such as trees, mushrooms, bacteria, seaweed, and wolves.

They may study the whole organism, evolutionary relationships, ecology, anatomy and physiology, or microscopic molecules and cellular processes.

Biologist work in the lab studying microscopic organisms, such as bacteria, or in the field such as surveying the diversity of plants in a forest.

Biology Program


  1. Communicate the current state of knowledge and technology to members of the community so that they may better understand how various aspects of the life sciences impact their lives, as well as local and global communities.
  2. Foster the scientific curiosity of students
  3. Prepare students to achieve academic and professional success.

Student Learning Outcomes

All Biology students will be able to:

  1. Apply core biological concepts that service as the foundation for higher-level science courses. These include theories of evolution, natural selection, processes of scientific inquiry, and proper laboratory techniques, among others.
  2. Evaluate the quality of scientific methodology when it is reported by the popular media.
  3. Describe the relationship between the process of science, human culture and the environment.


Biology Degrees

General Biology

A student in General Microbiology Biology is a natural science that focuses on physical and chemical processes of living organisms. This discipline explores how organisms acquire and use energy to maintain homeostasis, how they reproduce, and how they interact with each other and their environment. Scientific processes are emphasized as a means of answering these biological questions. Biologists rely heavily on a chemistry foundation since living organisms are chemical systems.

Allied Health

The allied health track in the biology program serves students satisfying prerequisites of nursing programs and other allied health fields. In addition to introductory general biology, students in the allied health track focus on human biology. Students in this program explore human body structure and function, from a micro-to-macroscopic level, including its homeostatic states and processes. Students also learn about microbial systems, and their role in nature and impact on humans.
