A.  Course Description:

 

      Prerequisite:  (ENC 0020 and REA 0002) or EAP 1695, and MAT 0024, or appropriate scores on the SPC placement tests. Biology of Marine Life is designed to provide the non-science major student with an understanding of basic biological principles using marine organisms as examples. The focus is on functional interactions at the cellular, organismal and community levels.  The laboratory component will apply concepts through direct observations and experiments using the diversity of organisms in and from our local marine environment. (This course may not be taken for credit subsequent to receiving a grade of “C” or better in any course with a BSC prefix.) Five hours weekly.

C.  Course Objectives Stated in Performances Terms:

     

      1.   The student will describe the unity among all life forms in their cellular structure, chemical and energy requirements and their ability to reproduce, develop and respond.

 

            The student will:

 

            a.   Identify prokaryotic and eukaryotic cells.

 

            b.   Describe those characteristics common to all life, including cellular structure; metabolism; reproduction and inheritance; growth (mitosis) and adaptibility.

 

            c.   List and explain the construction and function of carbohydrates, lipids, proteins and nucleic acids.

 

            d.   Associate major organic compounds with the nutrient cycles in the sea.

 

            e.   Recognize the necessity of ATP and DNA to survival and reproduction of cells and organisms.

 

            f.    Compare and contrast organisms from a plankton tow according to:

 

                  1)   prokaryotic vs. eukaryotic

                  2)   cellular features, size

                  3)   producer vs. consumer

                  4)   behavior (eg. taxes)

 

      2.   The student will design and analyze experiments using scientific methods.

 

            The student will:

 

            a.   Design investigations:  setting up hypotheses, predictions based on those hypotheses and controlled experiments to test them.

 

            b.   Demonstrate understanding of dependent and independent variables; graphing techniques and rudimentary data analysis.

 

            c.   Enumerate and explain the necessities and advantages of thorough, accurate data-keeping when conducting experiments or recording from the environment.

 

            d.   Gather pertinent bibliographies and information on studies being done by local marine research agencies.

 

      3.   The student will explain the basic energy processes within organisms.

 

            The student will:

 

            a.   Explain photosynthesis in basic terms, then relate it to the importance of primary productivity in the sea.

 

            b.   Explain cellular respiration, its reactants and products.

 

            c.   Compare photosynthesis and cellular respiration, including the reciprocity of components and the molecules used by each process for transferring energy.

 

            d.   Devise feasible experiments to test and monitor parameters such as compensation depth in a marine environment/laboratory.

 

      4.   The student will compare and contrast energy flow within the individual organism with energy flow in the ecosystem.

 

            The student will:

 

            a.   Recognize the relationship between adequate energy production (or intake) and maintenance of homeostasis within an organism.

 

            b.   Demonstrate an understanding of the flow of energy through a food chain in a marine ecosystem.

 

            c.   Link the length of a food chain and numbers at each trophic level with primary productivity and nutrient levels.

 

            d.   Exhibit proficiency in proposing, preparing and executing experiments designed for determining primary productivity in the ocean or laboratory.

 

      5.   The student will compare the influences of genetics and environment on  population growth and survival.

 

            The student will:

 

            a.   Compare meiosis to the basic reshuffling of genetic variables that promotes diversity in a population.

 

            b.   Use genetic principles to explain how  changes in allele frequencies can be influenced by changes in abiotic factors.

 

            c.   Correlate the rate of population growth with compatability between genetic requisites and environmental availability.

 

            d.   Understand how terms such as eurythermal, euryhaline, and osmoregulation relate to survival in different areas in the sea.

 

            e.   Associate the better understanding of the concept of a species with genetic research such as race studies in fish schools and gel electrophoretic identification of proteins.

 

            f.    Design experiments demonstrating survival rates and acclimation of estuarine organisms to variation in temperature and salinity.

 

      6.   The student will outline the evolution of diversity in marine life paralleling changes in time and environment.

 

            The student will:

 

            a.   Explain evolution in terms of natural selection.

 

            b.   Describe the changes in the marine environment with geologic time and how this has effected the kinds and abundance of marine organisms.

 

            c.   Demonstrate a knowledge of the main marine environments, including the photic zone, benthic zone, intertidal zone, estuary and the coral reef.

 

            d.   Compare marine environments using physical, chemical and geological characteristics as determining factors for their biotic communities.

 

            e.   Identify and appropriately use equipment for describing and testing environments, including a salinometer, a refractometer,  an oxygen meter, secchi disk, pH meter, graded sieves, Nansen bottle or equivalent, reversing thermometer, plankton net, seine, and trawl or dredge.
