the National Academy of Sciences definition of theory. ", Encyclopedia Britannica. ALL THEORIES BEGAN AS A HYPOTHESIS. Scientific method: The establishment of scientific theories is accomplished by following the scientific method. The scientific method is used in all sciencesincluding chemistry, physics, geology, and psychology. The best hypotheses are simple. It is a methodology designed to obtain answers to various disciplines, which may be scientific or not. Click 'Join' if it's correct. Form a hypothesis, or testable explanation. If garlic repels fleas, then a dog that is given garlic every day will not get fleas. Test of prediction: Plug the toaster into a different outlet and try again. A scientific theory is a theory based on suggestions. Alina's goal in life is to try as many experiences as possible. B) Eating fish reduces the chance of having a stroke. The method works from the setting of hypothesis regarding the phenomenon we want to study (in natural science, this phenomenon is called the system). C) Embryonic stem cell research will allow scientists to find a cure for diabetes. He argues that String Theory has become a degenerative research project, becoming increasingly complicated and, at the same time, removed from empirical reality. Page 18 of 24 Question 18 (3 points) Mendel made crosses between parental lines of pea plants that were homozygous for different alleles of the traits he was studying. d. the findings of a scientist receive the most 'up votes' during the first year they publish their work (q), You've made the following hypothesis: For example, one extract chlorophyll from grass and observe the color of the extract and ah, off the remaining grass. when a mineral is mined from the Earth Son rdacteur, Henry Oldenburg, en basait le contenu sur la correspondance qu'il recevait en tant que secrtaire de la Royal Society. Select one: A. reason why B. support C. claim D. benefits E. problem-solution According to Kuhn, there are several features of a good scientific theory. b. natural selection They deal with a relatively narrow set of phenomena. On the other hand, if results contradict a hypothesis, that hypothesis is probably not correct. 100 points to anyone who can solve these 5 questions, when you add reducing sugar to sweet poptato with the reagent sucrose powder,hydrochloric acid,an sodium hydroxide, Ashley is very nervous for her first speech. While every effort has been made to follow citation style rules, there may be some discrepancies. E. Drug Therapy, HELP PLEASE Which of the following best describes a scientific theory?

CI enables teachers to teach at a high intellectual level while reaching a wide range of students. (c) Tides are caused by the moon. Neutrinos are fundamental particles that are difficult to detect as they have no electric charge and interact only weakly with matter. Of course, there is nothing that makes a guess 'educated'. Which of the following is a product-focused strategy based on a prediction about how the product will perform? 2. 200 N Live Science is part of Future US Inc, an international media group and leading digital publisher. If a person gets 7 hours of sleep, then he will feel less fatigue than if he sleeps less. Let's suppose that you get two slices of bread, put them into the toaster, and press the button. In some instances, rather than rejecting a hypothesis because it has been falsified by new evidence, scientists simply adapt the existing idea to accommodate the new information. More than 200 N To date, she has been a volunteer firefighter, a dispatcher, substitute teacher, artist, janitor, children's book author, pizza maker, event coordinator and much more. Abstract. The more I think about it the more awesome that is, that the moon could or could not be the cause of the tide. Le bassin versant de Ogo connait des contraintes climatiques, cologiques fortes et changeantes. In the following scenario, identify which of the statements represents a theory, law, or hypothesis. Following Eric Weinstein's interview on how String Theory culture has stifled innovation in theoretical physics, longstanding critic of String Theory, Peter Woit, takes aim at the theory itself. b. theories may be changed or replaced if new evidence is found. A. Inertia explains why things stay in motion but not why they stay at rest. A scientific theory is more like a fact than a guess because it is so well-supported. I thought a hypothesis was an "if, then" statement, and not a prediction? Results that support a hypothesis can't conclusively prove that it's correct, but they do mean it's likely to be correct. Are you afraid to say what you mean? Apprehension Answer: A 13) Which of the following is not part of a good scientific theory? c. repeated testing from different scientists confirms the findings The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an "Ifthen" statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation . Keep in mind, a hypothesis is a possible answer to a scientific question. like this statement I think is a perfect example of philosophy and physics. B is not a scientific hypothesis because it is making a philosophical statement rather than a scientific one. For example, you might say, I think a woodchuck dug this hole in the ground, but its just a theory. Using the word theory in this way is different from the way it is used in science. If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities. Like the other scientific theories, lots of evidence has been identified that supports this theory, and no evidence has been identified that proves the theory is incorrect. A) Antioxidants from food are better than antioxidants from a vitamin pill. Which of the following would be a good, control in an experiment that tests the effects of tributyltin on developing. Evolution is a change species over time. d. A theory is a hypothesis that uses laws and observation to make an assumption. For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation. If the hypothesis was supported, we might do additional tests to confirm it, or revise it to be more specific. Le Consortium pour l'annotation, l'analyse et l'archive de la vido appliques aux activits scientifiques (CANEVAS) a t cr et labellis par Huma-Num en 2022. Their consequences can be tested by different investigators. The germ theory proposes that microorganisms are the cause of many diseases. But in the example above, it doesn't use an if/then statement. In conclusion, the statement concerning scientific hypotheses which is false is that they are the same as theories. Is the ball in equilibrium when it moves at constant speed in a straight-line path? Direct link to Midnight crow's post What if one time an exper, Posted 5 years ago. (a) Chlorophyll makes grass green. (D) Theories are proved true; hypotheses are often contradicted by experimental results. The. Once again, no evidence has been identified that proves this theory is incorrect. Theories are hypotheses that have been proved., Which statement best distinguishes hypotheses from theories in science?a. The scientific method. Those who have adaptations who help them survive longest reproduce more and pass down traits to offspring. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon.For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. For example, a hypothesis might state, "If animals adapt to suit their environments, then birds that live on islands with lots of seeds to eat will have differently shaped beaks than birds that live on islands with lots of insects to eat." A. a plausible answer to a scientific question that is used to guide research B. a highly tentative statement about the natural world that is likely to be significantly changed or discarded C. a broad, well-supported explanation of related observations or events D. a description of a natural phenomenon that is always observed to occur under specific conditions, If you cross a mussel with dark, zebra-striped shells with a mussel with solid light-colored shells, how many offspring would you expect to have the h A hypothesis can be rejected or modified, but it can never be proved correct 100% of the time.

This question is from the prologue:Exercise #1: Which of the following are scientific hypotheses? Sometimes, errors take place during an experiment. It can change with the new evidences. No evidence has been identified that proves this theory is incorrect. Thus, a scientific hypotheses are generally considered to be tentative or an educated guess. When crossing two parents, the. (C) Hypotheses usually are relatively narrow in scope; theories have broad explanatory power. That means that it should be possible to prove it wrong. . According to the cell theory, the cell is the smallest unit of structure and function of all living organisms, all living organisms are made up of at least one cell, and living cells always come from other living cells. Snapsolve any problem by taking a picture. The scale, developed according to the PHE model theoretical framework, is the first . D. He demonstrated that light and heavy objects gain the same amount of speed when falling. Exactly, like others said if you do more experiments, then you will be sure to find out which info is credible. He discovered that heavy objects roll faster than light objects on an incline. Direct link to shreyamundhada1's post A hypothesis is a guess o, Posted 4 years ago. Sociological theory and method have been used to develop a theory of complex instruction (CI). Well from science I know Tides are caused by the moon. about its axis because living things need an alternation of light and darkness. C. When you jump, your velocity relative to the Sun goes to zero because the forces on you are in equilibrium. Ah, to the moon's position. In natural selection, some living things produce more offspring than others, so they pass more genes to the next generation than others do. a. I think it is a fact that chlorophyll makes grass green because we know grass has chlorophyll and we know that chlorophyll is green. b. Forensic psychology is the intersection of psychology and the law, where scientific principles and practices are combined with legal theory and procedure. d. germinated after a fire (q), Genetics - Recombinant DNA and Gene Therapy, Biology;2.2;Prokaryotic and Eukaryotic cells, Biology 1.4/1.5;Characteristics of life/princ, John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine, David N.
