Which of these substances are greenhouse gases?

Those are answer's I chose, if there are more or less, please correct me.

Please give a brainliest and a thanks.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

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.
