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.

- Which one of the following statements are not true about a scientific theory? A. Cannot be dedcued based on repeated observations without an experiment designed to test the hypothesis. B. Could be radically revised based on new scientific evidence. C. A basic principle derived from the study of nature that has never been disproven by scientific inquiry. D. It is a general and reliable explanation of important natural phenomena.arrow_forwardState whether the following statements are true or false. (a). A hypothesis must be testable and fasifiable. (b). Failure to falsify a hypothesis proves that hypothesis. (C) In the context of science, a law is general and can lead to new testable hypotheses.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
- In 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_forwardThe _______ is manipulated by scientists over the course of an experiment. A.)dependent • variable B.)data C.)independent variablearrow_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_forwardIdentify which characteristics of living things is being described in each of the following statements below. Some may be used more than one time. arrow_forward
