Explanation:

A hypothesis is a proposed explanation or prediction that can be tested. The statement "If the amount of oxygen in water decreases, then rainbow trout will have an increase of lice on their skin" is a testable prediction about the relationship between two variables (oxygen in water and lice on trout), which fits the definition of a hypothesis. A scientific theory is a well - substantiated explanation of some aspect of the natural world, and a scientific law is a statement based on repeated experimental observations that describes some aspect of the universe. This statement is not a well - established theory or a law.

Answer:

hypothesis
