Some frogs, when sitting, can absorb all the oxygen they need through the skin. only when they move do they start to breathe. explain these observations.

In order to move you need oxygen and water to form the energy to function. The frog is basically drinking water and doesn’t need to move while doing so. You only need to breath to allow your body to move.

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.
