Yes because we often used it and takes long time to spent and forgot to eat on time.
The answer is DC power had to be converted in AC.
DC power is not usually in home. DC current must be converted to to AC, which is the standard in homes and to avoid short circuits.
DC or direct current explains the basic idea of electricity as a flow of electrons.
AC, also known as alternating current, electricity switches direction around 50-60 times each second. In here, electrons do not necessarily have to run in circles to transport energy, they simply run on the spot.
A sign of genetic mutation is a missing finger or an extra limb of some sort. Also people who study the human genome can trace gene pairs that are not complete or mixed up which can cause genetic mutations.
