Is the claimant very cold in the northeast region all year long

It really depends on where in the north west you are. In and around Maine, it's normally pretty cold; even in the summer (at least where I live) but in Rhode Island, Massachusetts, New York, etc. I'm pretty sure it isn't always cold. In the summer, the thermometer can reach up to 110 degrees, but the temperature can lower all the way down to -45 degrees and possibly lower.

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.
