Question

which of the following would be a testable hypothesis for an experiment that compares the health of salmon raised in fish farms to salmon caught in the wild?
a. salmon living in the wild experience fewer diseases than salmon raised in fish farms.
b. do salmon raised in fish farms experience more diseases than wild salmon?
c. if a salmon is raised in a fish farm, then it may be less healthy than a wild salmon.
d. eight wild salmon and eight salmon from a fish farm are examined for diseases.

Explanation:

A testable hypothesis is a statement that can be tested through experimentation. Option A is a statement that can be tested by comparing the number of diseases in wild salmon and farm - raised salmon. Option B is a question, not a hypothesis. Option C is a vague statement as it says “may be” which is not as testable as a definite statement. Option D is a description of an action (examining salmon) and not a hypothesis.

Answer:

A. Salmon living in the wild experience fewer diseases than salmon raised in fish farms.
