Concept explainers
To review:
The given blank space in the statement,” A _____ is a general explanation of natural phenomenon supported by extensive, reproducible test, and observation. In contrast, a _____ is a proposed explanation for observed events. To assume specific question about life, biologists use a general process called the _____.”
Introduction:
The scientific method is among the best-analyzed tool in order to accept or reject a hypothesis framed for a question based on certain observation. However, the scientific method is not similar to that of scientific theory. Their bases on the grounds of experimentation and conclusion vary a lot. Eventually, these two methods are used for completely different research areas helping in manipulating an expected result.

- Why 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_forwardIn science, a theory is best defined as a(n) Select one: a. educated opinion about the natural world. b. explanation for a large number of findings in the natural world. c. personal understanding of natural laws. d. testable prediction about the natural world. e. speculation and opinion of facts.arrow_forwardMatch the following words with each definition. (Hypothesis, theory, fact) A)a tentative explanation for a natural phenomenon. B) a repeatedly observation that everyone can agree on. C.) a widely accepted explanation for a natural phenomenon.arrow_forward
- What are the essential characteristics of science? Describe how evolu-tionary studies fit these characteristics whereas “scientific creation-ism” or “intelligent-design theory” does not.arrow_forwardWhich of the following is not true of science?a. Science is based on the premise that all events can be traced to natural causes.b. Important science can be based on chance observations.c. A hypothesis is basically a wild guess.d. Scientific theories can potentially be disproved.arrow_forwardThe scientific method is a set of techniques for gaining new knowledge about the world in which we live. However, these techniques come with a rigid set of rules that are sometimes misinterpreted. Identify the statements that accurately describe science and the scientific method. Scientific hypotheses are educated guesses that can be disproven by experiments. Science is a process that is limited to answering questions about the natural world. Science is a process that is not limited by the types of questions it can answer. Scientific findings can always be relied upon as fact. Scientific findings are based on carefully tested and scrutinized observations. Scientific theories are concrete and indisputable explanations for natural phenomena.arrow_forward
- Why is it likely to be too simplistic to describe accurately what happens in nature?arrow_forwardFollowing a scientific method, which of the following is the correct order of steps? A) Observation → Analysis → Hypothesis → Conclusion → Communicate results → Experiment B) Observation → Hypothesis → Experiment → Communicate results → Analysis → Conclusion C) Experiment → Hypothesis → Observation → Analysis → Conclusion → Communicate results D) Observation → Hypothesis → Experiment → Analysis → Conclusion → Communicate resultsarrow_forwardWhen doing science writing, it is okay to use direct quotes, phrases, or strings of words from another source as long as you give credit to that source. O Yes, science writing often includes direct quotes, phrases, or strings of words from other sources. These quotes are always carefully attributed to their source. O No, science writing does not include direct quotes, phrases, even strings of words from other sources. When doing science writing, you are expected to explain things in your own words. In-text citations allow you to use the ideas found in a source, but not its words.arrow_forward
- Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. If we move beyond the human body, the biological level of organization would then continue as follows; population, community, ecosystem, and finally, the biosphere, and if the biosphere is to organism, then a human is to a cell. b. Creating levels of organization of the structures of the body makes it easier to study and understand the structures and functions of the human body. c. Among the level of organization, the organism is the most important due to its sheer complexity.arrow_forwardConsider the steps involved in an experiment that uses the scientific method. Arrange the six given steps in the order in which they occur. One of the steps will not be used. First step of investigation Final step of investigation Answer Bank Share the results and conclusions of the experiment. Choose the data that are most likely to support the hypothesis and ignore the rest of the data. Conduct the experiment and collect the resulting data. Make observations that raise a question about some aspect of a natural phenomenon. Analyze the data collected in the experiment. Form a hypothesis that can answer the question about the natural phenomenon. Design an experiment that tests the hypothesis.arrow_forwardWhat is the difference between a scientific theory and a hypothesis? Why do scientists refer to basic scientific principles as “theories” rather than “facts”?arrow_forward
