How does the sun compare to other stars on the hr diagram in terms of brightness and temperature

Weighted by the stellar luminosity function, the sun is somewhat above the average temperature and very much above the average luminosity. Only 4% of main sequence stars are significantly brighter and hotter than the sun. About 6% of main sequence stars are about the same brightness and temperature. About 90% of main sequence stars are significantly dimmer and cooler than the sun. However, most of our galaxy's light (about 88%) comes from spectral type B stars, even though only one star in each thousand stars belongs to this type.

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.
