The unit for power in electricity should be watt. The power show how many energy transferred during a time and the SI unit would be joule per second.  

The bill is charging for the amount of energy. The energy could be calculated by multiplying the power with time. In this case, the power in kilo watt will be multiplied by the duration in hour which make the kilowatt hour.

Answer:

The consumer is being charged for electricity.

Explanation:

Kilowatt hours is a measure of the electricity consumed by a device during a certain period of operation.

Watt-hour is a unit of energy measurement and hour is a unit of time. One Watt-hour is the amount of energy required to power a 1 Watt load for 1 hour.

The power shown on each device indicates its power for a period of 1 hour. For example, a device with a power of 5400 W (Watts) will consume that power in one hour. The higher the power of a device, the higher its energy consumption. And the longer the device stays on, the more it will consume.

The fossil record of birds is incomplete because bird skeletons are
Bogdan [553]
Bird skeletons are very delicate, and therefore, difficult to be preserved.  The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.

The head of a phospholipid can be described as _____.
sergij07 [2.7K]
I believe that the answer to this would be polar and hydrophilic (soluble in water). The answer would be the third option. What makes the head of a phospholipid hydrophilic is that its polar head is negatively-charged and made by a phosphate group. Hope this helps.
