The correct answer is vacuole. Vacuole controls the water input and water output of an amoeba. It is found within endoplasm. The vacuole is an essential part of an amoeba because it maintains the life of an amoeba. Malfunction can cause the amoeba to burst.
Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.
<h3>Mutation</h3>
This refers to a sudden change to the DNA sequence of living organisms.
When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.
For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.
In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.
