ACells that perform similar functions combine to form: tissues. A group of tissues working together combine to form an organ system. Organs working together combine to form an organ system. Organ system performing their functions makes an organism.

Explanation:Cells that perform similar functions combine to form tissues. group of tissues working together combine to form an organ system. Organs working together combine to form an organ system. Organ system performing their functions makes an organism.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
