1. A sockeye salmon spent his first year of life in a freshwater stream. He is now ready to move into the ocean but must first go through 'smoltification', the physiological transition from a freshwater teleost to a marine teleost. Explain the physiological changes that occur, using your knowledge of the ionoregulatory and osmoregulatory challenges faced by teleost fish in freshwater versus marine environments and the strategies they use to overcome these challenges.
2. Structure and function are often intimately linked in physiological systems, i.e. structures may be uniquely adapted to carry out particular functions, or the function of a particular system is made possible by its structure. Discuss such structure-function relationships with respect to the filtration.
