Which of the following structures or systems is correctly paired with its function?

central nervous system - processes information and controls responses

cerebellum - portion of the brain that controls body movement

neurons - brain cells that control thoughts, calculations, and memory

peripheral nervous system - releases hormones and controls emotions

I think I'd go with this one: Central nervous system - processes information and controls responses. It looks like correct pair.

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.
