Concept explainers
(a)
Interpretation:
The difference between a hypothesis and the theory has to be given.
(a)

Explanation of Solution
Hypothesis:
A hypothesis is a reasonable guess based on the limited data which acts as a foundation for the further investigation. A hypothesis is not tested and proven scientifically. The results are uncertain and it relies on the possibility.
Theory:
A theory is a well correct explanation of a natural phenomenon that is validated through observation and experimentation and it is base on wide range of data. A theory is tested and proven scientifically and the results are certain and it relies on evidence.
(b)
Interpretation:
The difference between theory and scientific law has to be given.
(b)

Explanation of Solution
Theory:
A theory is a well correct explanation of a natural observable fact that is validated through observation and experimentation and it is base on wide range of data. A theory is tested and proven scientifically and the results are certain and it relies on evidence.
Example:
A theory tries to provide the most logical explanation about why things happen as they do. A theory might raise dominant and recessive genes to explain how brown-haired parents ended up with a red-headed child, or use gravity to shed light on the parabolic trajectory of a baseball.
Scientific law:
A scientific law is the description of an observed fact. It doesn’t explain why the observable fact exists or what causes it.
Example:
A scientific law predicts the results of unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle.
