Write a comprehensive definition of theory,law or principle

• THEORY

When a hypothesis is a give a repeated exposure  to experimentation and is not falsified,it increases biologists'confidence in the hypothesis.Such well-supported hypothesis may be used as the basis for formulating further hypotheses which sre again proved by experimental results. THe hypotheses thet stand the test of time (often tested and never rejected),are called theories. A theory is supported by a great deal of evidence.

• LAW OR PRINCIPLE

 Productive theory keeps on suggesting new hypotheses and so testing goes on. Many biologists take it as a challenge and exert greater efforts to disprove the theory.If a theory survives such doubtful approach and continues to be supported by experimental evidence, it becomes law or principle. A scientific law is a uniform or constant fact of nature. It is an irrefutable theory. The example of biological laws are hardy-weinberg law and mendel's laws of inheritance.
