The Natural Sciences Department: Biology

Here is an overview of the course offerings in the Science Department at York County Community College

Biology Courses

BIO 101 – Introductory Biology

Course Description:  This overview of biology is designed for non-majors who need a general lab science course to meet their graduation requirements.  Selected topics from cell, molecular and organismal biology will be covered, with a focus on understanding how evolution has shaped life forms, and how life forms interact with the environment.  During laboratory exercises, students will use the scientific method to generate new knowledge, then communicate that information to others. 

Prerequisite: Grade of C or better in MAT 050 or MAT 065 or appropriate Mathematics Placement Exam..


BIO 105 - Marine Biology/Lab

4 credits/5 contact hours

This course is an introduction to marine plants and animals, especially those native to the area. Students will be introduced to the biological processes of all forms of life in the sea. This course employs YCCC’s proximity to ocean and estuaries as a natural field laboratory. Prerequisite: Grade of C or better in MAT 050 or MAT 065 or appropriate Mathematics Placement Exam.


BIO 106 - General Biology I
4 credits/3 contact hours
Biology I provides a comprehensive examination of the fundamental concepts of biology, including the chemical properties of life, cellular biology and physiology, and genetics. Evolution will be utilized as the central theme in all discussions; providing a coherent view of life in the light of natural selection and the diversity of species. This class assumes previous experience with scientific laboratory course work. Must be taken concurrently with BIO 107. Prerequisite: Grade of C or better in MAT 050 or MAT 065 or appropriate Mathematics Placement Exam.

BIO 107 - General Biology I Lab
0 credits/2 contact hours
This laboratory provides experience with the concepts and principles covered in General Biology I (BIO 106). Laboratory exercises relate to lecture topics and introduce students to the fundamentals of laboratory procedure, as well as providing an applied reinforcement of lecture topics. Must be taken concurrently with BIO 106. Prerequisite: Grade of C or better in MAT 050 or MAT 065 or appropriate Mathematics Placement Exam.


BIO 116 - General Biology II
4 credits/3 contact hours
General Biology II provides a rigorous examination of modern biological theory, as well as an introduction to the anatomy and physiology of animal systems. Topics include natural selection and the evolution of populations, phylogeny, plant and animal diversity, and animal form and function. Must be taken concurrently with BIO 117. Prerequisites: BIO 106/BIO 107.

BIO 117 - General Biology II Lab
0 credits/2 contact hours
General Biology II Lab presents exercises that relate to the General Biology II lecture topics and introduce students to the fundamentals of laboratory procedure, as well as providing an applied reinforcement of lecture topics. Must be taken concurrently with BIO 116. Prerequisites: BIO 106/107.


BIO 120 – Human Nutrition

3 credits/3 contact hours

This course examines the basic principles of human nutrition during the lifecycle from infancy throughout adulthood.  The functions of carbohydrates, proteins, lipids, vitamins, minerals, and water will be discussed in relationship to growing and maintaining life. The effects of a deficiency or overabundance of each nutrient will be explored, as well as the role of nutrition in preventing and managing human diseases such as obesity, eating disorders, diabetes, osteoporosis, heart disease, and cancer.  Prerequisite:  none


BIO 230 - Microbiology
4 credits/3 contact hours
The biology of bacteria, fungi, protozoa, helminths and viruses will be presented, with an emphasis on those that impact humans. The structure, growth and metabolism of microbes will be examined in the context of their physical, chemical and biological environment. Mammalian immunity and antimicrobial methods will also be explored. Must be taken concurrently with BIO 231. Prerequisites: BIO 136 and BIO 137 (can be taken concurrently).


BIO 231 - Microbiology Laboratory
0 credits/2 contact hours
The laboratory will focus on the culturing and identification of microbes using differential growth, staining and biochemical methods. Aseptic technique will be emphasized. Must be taken concurrently with BIO 230. Prerequisites: BIO 136 and BIO 137 (can be taken concurrently).
