Which is a difference between a compound light microscope and a transmission electron microscope? A. The compound light microscope can only view specimens in black and white, while the transmission electron microscope has color.
B. The compound light microscope can view living things, but the transmission electron cannot.
C. The compound light microscope examines the surface of a cell, and the transmission electron microscope examines internal parts of the cell.
D. The transmission electron microscope is used for dissections, while the compound light microscope is not.

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 element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

and after water is usually warmed by the sun the water temperature raises and then evaporates .
