Suppose you were observing an amoeba under the microscope and it suddenly exploded. what organelle was probably not working properly in the amoeba?

The correct answer is contractile vacuole.

The contractile vacuole is a water bubble present in the endoplasm of the amoeba. The role of the contractile vacuole is same as the role of the central vacuole in plants.

The contractile vacuole stores the water and the waste material of the cell, along with some mineral and other substance, so, they help in the maintenance of the osmolarity. In case, the walls of the contractile vacuole is damaged, the cell may burst out.

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
