The nurse is reviewing principles of immunity. what type of immunity occurs when the body is exposed to a relatively harmless form of an antigen, which imprints this information on the body’s memory bank and stimulates the body’s defenses to resist any subsequent exposures?

Artificial active immunity. I'm a bio major, hope I helped :)

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.
