Which of these are minerals? a. iron and water b. plants and water c. gold and bauxite d. concrete and bauxite

I say *C*, Gold and Bauxite.

The correct answer would be C. Gold and bauxite 

Native (or raw) gold is a mineral and bauxite is full of minerals.

Looking at the rest of the answers, water, plants and concrete are no minerals, therefore they cannot be the answer.

Hope this helps!

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.
