3. Which of the following is a defining characteristic of a prokaryotic cell? a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement

C

Explanation:

Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

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.
