for your time!

I think the correct answer from the choices listed above is option D. His findings would explain that the ancient land area was invaded by the sea.  Its because that the lizard-like dinosaur and the fern like tree were buried underneath the fish fossil and the shellfish fossil.

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.
