Summary Introduction
Introduction: Hypothesis is defined as a suggested or proposed reasoning for a phenomenon that is naturally occurring in the environment. A hypothesis may be accepted or rejected based upon its validation. After observing certain desert plants in their native environment, a researcher proposes that they drop their leaves to conserve water. This is an example of a hypothesis.

- When there is a lot of evidence to support and not sound evidence to disprove an explanation for a phenomenon in science, the idea is elevated to A. explanation B. experimentation C. theoryarrow_forwardII.) Answer as comprehensively and as briefly as you can. When is a hypothesis accepted? Why is a variable included in an experiment? Discuss the importance of a control in interpreting the results of an experiment? What are the reasons for conducting an experiment? Differentiate discovery-based from hypothesis-driven science? Explain how the scientific way of learning and solving problems can be useful to you.arrow_forwardWhy is forming a hypothesis an important step in the scientific method? Choose the best answer. Stating a hypothesis before conducting experiments ensures that the method will follow an inductive process of reasoning. By stating a formal hypothesis, a scientist can adequately design the best control conditions for designing experiments intended to falsify the hypothesis. When a formal hypothesis is tested once, it will be accepted as theory no matter what the results of subsequent experiments suggest.arrow_forward
