Why is scientific theory revised over time?

Why would a scientific theory be revised over time? because new theories can come out that better explain observations and experimental results can replace old theories.

Why are scientific ideas modified?

A scientific idea is an explanation of how something works, or the truth about some aspect of the world, that was figured out using the scientific process. Scientific ideas change over time as our evidence improves. The more experiments we do and the more data we collect, the better our scientific ideas become.

What causes a theory to be modified?

Accepted theories may be modified or overturned as new evidence and perspective emerges. Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more.

What is a scientific idea modified?

Scientific ideas rarely change, because they are based on extensive evidence. New evidence leads to modification of ideas. As a scientific idea changes, it eventually becomes a scientific theory and then a law. A theory will never change.

What does modify mean in the scientific method?

Modifications in Science When the data is taken, predictions are needed, with which the observations can be compared. We may observe something unexpected or the data might prove inconclusive. Or those might partially support the idea, causing to modify our hypothesis or change the experiment.

In which situation would new technology be most likely to cause a change in an existing theory about new structures 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 happens when new information is discovered that contradicts an existing theory?

In science, a tested explanation of why things happen that is accepted to be true is called a scientific theory. 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.
