Are mutations mostly good and add to the advancement of the organism or mostly harmful resulting in the damage or possible death of the organism, or are neutral having no effect on the organism? Give statistics and cite your source of information. plz help! thx

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.

Self-reports would be the answer.
