Question

about the origin of life on Earth can be stated as a hypothesis and investigation by scientific methods? why?which cannot be? why not?

Answer 1

The scientific method When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory. The steps of the scientific method go something like this: Make an observation or observations.Ask questions about the observations and gather information.Form a hypothesis — a tentative description of what’s been observed, and make predictions based on that hypothesis.Test the hypothesis and predictions in an experiment that can be reproduced.Analyze the data and draw conclusions; accept or reject the hypothesis or modify the hypothesis if necessary.Reproduce the experiment until there are no discrepancies between observations and theory. “Replication of methods and results is my favorite step in the scientific method," Moshe Pritsker, a former post-doctoral researcher at Harvard Medical School and CEO of JoVE, told Live Science. "The reproducibility of published experiments is the foundation of science. No reproducibility – no science." Some key underpinnings to the scientific method: The hypothesis must be testable and falsifiable, according to North Carolina State University. Falsifiable means that there must be a possible negative answer to the hypothesis.Research must involve deductive reasoning and inductive reasoning. Deductive reasoning is the process of using true premises to reach a logical true conclusion while inductive reasoning takes the opposite approach.An experiment should include a dependent variable (which does not change) and an independent variable (which does change).An experiment should include an experimental group and a control group. The control group is what the experimental group is compared against.
