Apick is used to:
a
add height
b
add wood
c
clean out the hot glue gun
d
hold ribbon in place

I'm debating on C or D, But my guess is to go with D. I'm not too positive but i tried. It makes the most sense with a pick. you don't really clean out glue guns with a pick. And A and B makes no sense for a pick

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.
