What is the relationship between evidence, conclusions and theories.will mark brainliest
Pie

Answer:

They are inter-related with each other.

Explanation:

There is a great relationship present between evidence, conclusions and theories because evidences are those materials due to which a hypothesis can be verified and we can draw conclusion. When we repeat the same experiment and find out the same conclusion so it becomes theory and when these theories can't change with the passage of time, it becomes law. So evidence, conclusions and theories are inter-related to each other.
