To survive natural selection, one must be fit and be able to adapt to the environment and situations, thus why it's called survival of the fittest.
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.

Answer:
The answer is C- Lysosomes are present in both bacterial and animal cells.
Explanation:
Lysosomes contain digestive enzymes inside them, which when released break down damaged cell parts. These enzymes are <em>acidic</em> in nature and are separated from other organelles with the help of a membrane.
Lysosomes help in<em> killing bacteria and virus</em> invading the cell body. Lysosomes also take part in the process of cell death known as '<em>apoptosis</em>'. This happens only when a certain cell is beyond repair.
Lysosomes are present in plant cells, animal cells, bacterial and yeast cells.
