Answer:
There can be no conclusion drawn from the debate that whether hereditary and environment are involved in the building of the organism.
Some of the features of the organism are dependent on the environmental factors and some of the factors are related to the hereditary of the organism.
Example: The tail of the rat was cut and the next generation that was born with tail and in this case there is no role of the environmental factors on the mice.
A person has no health issues but gets affected by the nearby environment and is diseased. In this case there is no role of hereditary on the person.
So, there cannot be any conclusion of such topics. Both of the factors are equally important.
The results of a scientific investigation either support or do not support a claim; they do not offer conclusive reports.
<h3>What is an experiment?</h3>
An experiment is a test under controlled conditions to either demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.
Prior to experimentation, a hypothesis must be constructed, which is a testable prediction on the outcome of the experiment.
However, a hypothesis cannot be proven conclusively to be true but can only be accepted or not accepted.
Therefore, the results of a scientific investigation either support or do not support a claim; they do not offer conclusive reports.
