Why no water needs to be added to a tightly fitting cork, clear glass jar and moist, unsterillised soil

one of the by products of photosynthesis is actually H2O, it evaporates and comes back down into the soil and does the whole cycle again!

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

the answer is golgi apparatus
