Ascientist measures the weight of two different animals one is 250 grams and the other is 330 grams in milligrams what is the difference between the two weights of the animals

For the first animal: 250x1000=250000 mg

for the second animal: 330x1000=330000 mg

to find the difference: 330000-250000=80000 mg (which is your final answer)

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.
