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.)
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.)
LS318 Conservation Biology & Sustainability (4)
This is a comprehensive study of ecological legal issues and the stewardship of stainability of ecological quality of life
and diversity. The bulk of the laboratory will be outdoors. 3-hour lecture and 3-hour laboratory and field work. (Lab
LS321 Human Anatomy (4)
A study of human micro and gross anatomy from a systematic approach. The laboratory consists of the use of human
models, cats, mammalian body parts, and human histology slides. 3-hour lecture and 2½-hour laboratory. (Lab fee: $75.)
Prerequisite: LS150, LS151, or LS252 recommended.
LS322 Human Physiology (4)
An integrated study of the functions of the human body systems in the context of homeostatic control and disease
conditions. The laboratory involves clinical applications to the health sciences. 3-hour lecture and 3-hour laboratory.
(Lab fee: $75.)
Prerequisite: LS150, LS151 and LS252 recommended.
LS331 Developmental Biology (4)
Students become familiar with the stages of fertilization and the early developmental patterns of representative animals.
Emphasis is placed on the genetic basis of differential gene expression during the various stages of development. The
lab involves microscopic examination of prepared serial slides of frog, chick, and pig embryos at various stages of
development. 3-hour lecture and 3-hour laboratory. (Lab fee: $75.)
Students are expected to be enrolled in the lecture concurrently.
LS332 Population Genetics (4)
Classic Mendelian genetics and non-Mendelian genetics are covered in the context of populations in their natural
environment. Genetic variations within populations and their impacts upon acclimatizations are studied in detail.
Modern molecular genetics are used in identification of pure lines and population interactions. The laboratory involves
the study of Drosophila melanogaster populations and identification of allelic frequencies in successive generations and
non-Mendelian interactions. (Lab fee: $75.)
LS341 Ecology (4)
The study of organisms in relation to the environmental complex (the composition, dynamics succession, and growth
of plant and animal communities) including field study. 3-hour lecture and 3-hour laboratory. (Lab fee: $75.)
LS140 or LS150 or LS151 and M262
