The fact that a hypothesis can be tested means that

a. research can be done about similar experiments

b. evidence can be gathered to support the hypothesis

c. it is the kind of thing that might be asked about on a science test

d. an experiment about the hypothesis has already been completed

B. evidence can be gathered to support the hypothesis

Explanation:

Knowledge is produced based on observed phenomena, known facts or facts based on theoretical data. In this context, the development of hypotheses is of paramount importance. We can conceptualize hypotheses as supposed answers to a problem in question.

When we are doing our studies, the hypothesis goes through two processes, they are: (1) Formulation of the hypothesis and (2) Test of the Hypothesis. In order to seek solutions for the study in question, the hypotheses can be proven or refuted, which is why testing them is so important. When a hypothesis can be tested it means that evidence can be gathered to support that hypothesis.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
