Polar , bent , polar

An SCl2 molecule has polar bonds and a bent molecular shape. As a result, an SCl2 molecule is polar.

Explanation:

idk what the question is about

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
