Answer: A
Explanation: Just took the quiz
The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
<h3 /><h3>What is a random mutation?</h3>
Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.
Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

An integrated explanation supported by extensive observation and experimentation and evaluated by the peer review process is called a scientific theory.
Peer review process is the system of analyzing and assessing the written manuscript before it is published in any journal. The process is performed to evaluate the dignity, originality and the significance of the manuscript. There are around 10 steps in the review process.
Scientific theory is a series of explanations for various facts and observations. The scientific theory should have some relevance, and if possible valid evidences as well. A theory can be proved even with the help of experiments.
