Give an example of a scientific question that could be investigated by and experiment

Do molecules move faster when they are hotter? This could be investigated by heating water and making cold water and dropping dye in. In hot water, it would move throughout faster, while cold water would go slow. Hope this helps! ;)

You e got the answer to the question right

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.
