5. which tool enhances a scientist’s senses? a microscope a stirring stick a test tube a calculator

The correct answer is A. A microscope

Explanation:

Microscopes are observation instruments with special lenses that allow scientist to observe small objects and organism in detail which is regularly not possible with limited human sight. Due to this, a microscope enhances or improves the sight sense by enlarging images of objects, indeed specialized microscopes can magnify an object up to twenty thousand times. Thus, the tool that enhances a scientist's senses is the microscope that enhances the sigh sense. Also, others such as test tubes or calculators are scientific tools but none of these can improve one of the five senses.
