Gregor Mendel was the first scientist to use statistics to analyze scientific data. Before Mendel’s experiments, scientists beli
eved that organisms acquired traits from their environment and passed them on to their offspring. After Mendel’s discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. This is an example of A) a theory changing because a new scientific method was developed.
B) a law changing because a new scientific method was developed.
C) a hypothesis changing because a new scientific method was developed.
D) an observation changing because a new scientific method was developed
The correct answer is A. In the scientific world, a theory refers to an explanation of an observed phenomenon, which had been severally tested by many scientists and which have become generally acceptable as correct and accurate. Scientific theories are usually based on careful examination of facts. Science is a very dynamic subjects and new discoveries are been made by scientists on a daily basis as a result of advance in science and technology. When new facts are discover about an existing theory, such a theory is usually updated in order to reflect the newly discovered facts.
