Plz ! which contribution added to rutherford's discovery of a positive nucleus? atoms are indivisible. electrons are scattered in an atom. neutrons are inside the nucleus of an atom. atoms of the same element have the same properties.

The answer is B.) Electrons are scattered in the atom

The answer is neutrons are inside the nucleus of an atom because when he did the gold foil experiment the light he cast on it deflected back to him because light does not pass through neutrons. (I think)

B] nitrogen fixationmight be wrong, so correct me.want extra on your answers? just go on my account and go on questions and answer, or ask in the comments!

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.
