The first step in the scientific method is to observe a natural phenomenon.

Identify the scientific statement

What is the nature of science?

What is the relationship between technology and risk?

The relationship between technology and risk is that any technology has some risks.

When the benefits of a technological innovation are seen to outweigh the risks then what?

The technology is accepted and applied.

What is the relationship of science and technology?

Science and technology are fundamentally different from each other.

How might the demand for reproducibility in science have the long-term effect of compelling honesty?

All of the Above. Any false claims are eventually uncovered. Scientists, therefore, stand to gain most from reporting their results truthfully. A scientist who has knowingly falsifies any bit of evidence runs the risk of losing credibility for all his or her life's work. Science is about discovering the rules of nature. A scientist who creates his or her own rules through dishonesty, which may not be reproducible in other laboratories, is not truly doing science.

If the victims' wounds healed within a few days, it's possible that the victims may have attributed the healing to the touch assist.

An education guess in science is what?

What does an effective scientific hypothesis provide?
