In osmosis explain why water moves toward a hypertonic area.

the water moves from an area of high concentration to low concentration. the pressure that must be applied to a semi-permeable membrane to oppose or prevent osmosis. ... The solute concentration is higher inside of the cell. Water concentration is greater on the outside of the cell.

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.
