Consider the following statements about Zebra Mussels:

Zebra mussels are native to the Caspian and Black Seas, located south of Russia and Ukraine, and they entered the Great Lakes in the late 1980s via ship ballast water, spreading to much of eastern Canada and the United States since then.

Consider the following statements about Zebra Mussels:Statement-I:Zebr...

Statement-I accurately describes the characteristics, impacts, and habitat of Zebra mussels, detailing their appearance, reproductive habits, ecological effects, and their tendency to cluster on various underwater structures. This statement provides a comprehensive overview of the invasive species and its behaviors.
On the other hand, Statement-II incorrectly provides information regarding the native habitat and introduction of Zebra mussels. Zebra mussels are not native to the Great Lakes region but are originally from the Caspian and Black Seas, entering North America through ballast water of ships. The statement inaccurately implies that the mussels are native to the Great Lakes, which is not the case.
