One reason that multiple approaches are often taken to answer a testable question is that scientists

look at each perspective on how the phenomenon might have took place in a different kind of perspective. Multiple approaches are explored to see which condition fits and answers the query the most -accurate and reliably.

Thus, to achieve the creative approach above the researchers must utilize and apply the scientific method in gathering, interpreting and analyzing empirical evidence. 

Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process.

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.
