(a)

Interpretation Introduction

Interpretation:

The difference between a hypothesis and the theory has to be given.

(a)

Expert Solution
Check Mark

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 Introduction

Interpretation:

The difference between theory and scientific law has to be given.

(b)

Expert Solution
Check Mark

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.
