3:  Design a research project to study and measure the evolving impact of R. venosa on Chesapeake Bay, as well as its potential impact on other habitats along the East Coast. Suggest means by which the whelk’s impact might be reduced or controlled.

4:  Explain how mute swans got to Chesapeake Bay.

5:  How do biologists kill (addle) mute swan eggs?
