In the 1800s and early 1900s, farmers and scientists were just learning that cross-breeding corn caused heterosis, allowing farmers to grow more corn per acre of land farmed. Two different varieties of corn were crossed reciprocally: Variety A yielded 20 bushels per acre and Variety B yielded 25 bushels per acre, and the resulting hybrid progeny corn produced 27 bushels per acre. What is the percent heterosis?

want or the answer

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.
