2 Points Which statement best describes the role of sugar in photosynthesis?
O A. Plants use oxygen to break down sugar molecules.
B. Sugar molecules are made from carbon dioxide and hydrogen
using the energy in ATP.
O C. Sugar molecules are used as food by plants.
D. Energy splits sugar molecules into hydrogen and carbon dioxide.

the answer is B.

Explanation: I just took the test.

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.
