A man has a weight of 833 N on Earth. What is his mass?

The weight is 834.
To find out the mass, we have to divide by 9.8 because we multiplied x (the mass = x) by 9.8 to get to 834.
834/9.8= 85.1 KG is the mass.

Brainliest?

Ithink its false. hope this : )

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
