BI 102C - General Biology-Marine Biology

4 Credit(s)

Overview of the structure and function of tissues, organs, and organ systems in marine invertebrate phyla and selected marine vertebrates like fish and sharks. Examines how organisms maintain homeostasis in various conditions. Includes a field trip to the coast.

Learning Outcomes
Upon successful completion of this course, the student should be able to:

  1. Demonstrate how various organisms function at the cell tissue, organ system levels. Describe special challenges faced by marine organisms related to gas exchange, nitrogenous waste removal and other physiological functions. Explain counter-current flow in gills and other systems.
  2. Model homeostasis and feedback loops in biological systems, such as alternate blood-flow pathways to adjust to different temperature extremes, adaptations for maintaining ion balance in the face of diffusion and osmosis in salt and fresh-water environments.
  3. Accurately describe, illustrate and explain the anatomy and physiology of different marine phyla, including sponges, anemones and other cnidarians, worms, mollusks, arthropods, echinoderms and chordates. Describe unique attributes and development of each organ system in various taxa.
  4. Compare and contrast how the above systems work in such different organisms as rotifers and fish, corals and squid, and many others. Describe the selective pressures favoring organ system adaptations.
  5. Evaluate and critique scientific information from various sources (journals, magazines, newspapers, television, and the internet) for reliability and validity. Develop internet search skills to find reliable information to use.
  6. Develop a scientific inquiry project using a research question and hypothesis about system level adaptations in a comparison of different taxa of marine organisms.
