LS220 Research Methods (1)
An introduction to research writing with emphasis on the documentation and communication methods used in
biological research. The student will be exposed to major aspects of scientific writing and presentation of scientific data,
including library research, data analysis, evaluation of scientific writing, composition of a scientific paper and a
prospective research proposal, and presentation of scientific data in a poster format. 1-hour lecture.
LS231 Human Growth and Development (3)
A study of human development across the lifespan from birth to death with emphasis on the physical, cognitive,
emotional, and social aspects of human life. (Directed study only).
LS252 Cell Biology (4)
The molecular basis for the various structures and physiological functions of prokaryotic and eukaryotic cells. Topics
include membrane structure-function, cellular energetics, receptors, and cell-cell communication. 3-hour lecture and 3-
hour laboratory. Concurrent laboratory registration required. (Lab fee: $75.)
Prerequisite: CH151 and LS151.
LS302 Vertebrate Anatomy and Systematics (4)
A study of chordate systematics, comparative anatomy, and morphogenesis. For all biology students with specific
relevance to students who choose the environmental emphasis or those interested in veterinary medicine. 3-hour lecture
and 3-hour laboratory. (Lab fee: $75.)
LS307 Biology of Dinosaurs (3)
A study of dinosaurs including their fossil record, systematics, origins, biology, and behavior. Discussion will focus on
controversies related to the proposed evolution of birds from dinosaurs and the reason for dinosaur extinction.
LS312 Animal Physiology (4)
Animal physiological systems and regulatory mechanisms are studied in the context of various types of ecosystems.
Consideration is given to regulatory adjustments to seasonal and environmental variations within an ecosystem. The
laboratory is a research-oriented study of the physiological adjustments of invertebrates and amphibians in seasonal
streams and in the lab. For all biology students with specific relevance to students who choose the environmental
emphasis or those interested in veterinary medicine. 3-hour lecture and 3-hour laboratory. (Lab fee: $75.)
