Question

6 multiple choice 2 points which of the following statements is a testable scientific hypothesis? antioxidants from food are better than antioxidants from a vitamin pill. eating fish reduces the chance of having a stroke. embryonic stem cell research will allow scientists to find a cure for diabetes. smoking makes people less attractive. drinking milk gives people a better smile.

Explanation:

A testable scientific hypothesis is one that can be proven or disproven through experimentation or observation. "Eating fish reduces the chance of having a stroke" can be tested by comparing stroke - incidence rates in groups that eat fish and those that don't. In contrast, "better" in the first option is subjective, finding a cure in the third option is a long - term prediction not easily testable now, and "less attractive" and "better smile" in the last two options are subjective.

Answer:

Eating fish reduces the chance of having a stroke.
