Quick please awnser The main function of the skeletal system is to -
o exchange gases, mainly carbon dioxide and oxygen, between the 2nosphere and the blood
support and protect organs such as the brain, lungs, and heart, and for muscle attachment
pump oxygen and nutrients through the blood to every part of the body
send signals in the form of hormones to the body to control growth, reproduction, and metabolism

Is there possibly mutliple choice answers or is this a type/write it in question?

Where is the rest of the question

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.
