For a question to be answerable by science, it must be testable. This means that there must be some thing that can be changed, an independent variable, and in turn, the results change.
Oftentimes, the scientific method is used when testing something. The steps of the scientific method are as follows:
Question: This is when something is observed, and you ask, "I wonder what would happen if..."
Hypothesize: this is where you try to guess the answer to your own question based solely on logic
Experimentation: This is where you actually design and conduct multiple experiments to test the hypothesis that you previously made
Observe: this is when you record the results of your experiment
Analyze: You look at the gathered data, and make come to a conclusion based on the results
And then finally,
Report/Share: This is when you actually deliver your findings to the scientific community/world
<span>The answer is nuclear imaging. A subject is asked to take in a radionuclide (radioactive
isotopes) and as the radioactive material passes though the body, it continually emits radiation that is detectable by an instrument such as a gamma camera. Examples of nuclear imaging
techniques are SPECT and PET.</span>
Between Earth and Moon there is a gravitational force that exists.
