Which statement represents a hypothesis that he can test to answer his question?
Conlan wants to answer the question, “Does phosphorus affect tomato fruit production?” Which statement represents a hypothesis that he can test to answer his question? If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes. testable.
Which describes how Francis would know the hypothesis is a theory?
Answer: Hypothesis is speculation, while theory is an explanation. That way, Francis will know that the hypothesis is a theory if a given hypothesis is tested and the test result explains a scientific phenomenon.
In which situation would new technology be most likely to cause a change in an existing theory about new structures a cell?
In which situation would new technology be most likely to cause a change in an existing theory about new structures a cell? The new technology makes it possible to detect and analyze a structure more rapidly. The new technology allows scientists to confirm the presence of an existing structure in a cell.
What situation would result in a theory being replaced rather than revised?
“New information is discovered that contradicts the existing theory” is the situation among the choices given in the question that would result in a theory being replaced rather than revised. so the answer would be New information is discovered that contradicts the existing theory.
What happens when new information is discovered that contradicts an existing theory?
However, science is an ongoing process and scientific theories continue to evolve. New observations can lead to new explanations. Erroneous theories are wrong, although the scientists might not realize it at the time. The discovery of new evidence will cause them to be rejected.
What do all hypotheses have in common?
Answer and Explanation: One major factor that a scientific hypothesis, theory, and law have in common is that they are all based on observations.
What is a simple hypothesis?
Simple hypotheses are ones which give probabilities to potential observations. The contrast here is with complex hypotheses, also known as models, which are sets of simple hypotheses such that knowing that some member of the set is true (but not which) is insufficient to specify probabilities of data points.
What is needed for a good hypothesis?
To devise and perform an experiment using the scientific method, you need to make sure that your hypothesis is testable. To be considered testable, some essential criteria must be met: There must be a possibility to prove that the hypothesis is true. There must be a possibility to prove that the hypothesis is false.
What is a good hypothesis statement?
A good hypothesis will be written as a statement or question that specifies: The dependent variable(s): who or what you expect to be affected. The independent variable(s): who or what you predict will affect the dependent variable. What you predict the effect will be.
What two words must be in a hypothesis?
The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables. The hypothesis should relate back to your original question and must be testable.
What do scientists mean when they say a hypothesis is fruitful?
A hypothesis, or theory, that cannot be verified independently of the phenomenon it’s supposed to explain. A fruitful theory is one that makes novel predictions.
