Question

Although scientific theories are based on strong evidence, they can change over time. Which of the following correctly explains why scientific theories change? (5 points) a New theories require changes to the scientific process, so the theory changes as a result. b Scientists are often incorrect in their initial hypotheses, so the theory changes. c Scientists argue, re-examine, and consider new explanations to new data. d Theories are hypotheses that have gained support and change as the hypothesis changes.

Answer 1

Answer:

C

Explanation:

Answer 2

Answer:

Scientists argue, re-examine, and consider new explanations to new data

Explanation:

Theories are susceptible to changes and new data can be incorporated into the theory because advances and discoveries are made.Scientific theories are testable and make falsifiable predictions thus, scientists argue, re-examine, and consider new explanations to new data.As additional scientific evidence is gathered, a new scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings.

Although theories are only modified in most cases, when a theory lacks any of the following characteristic they are susceptible to rejection by the scientists. A theory must be observable and repeatable to avoid frauds. Theories should be testeable and make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry. It should also be well-supported by many independent strands of evidence. In addition, having consistency with preexisting experimental results and accuracy in its predictions as in any preexisting theories. All the above features provide room for change in theories over-time.
