This finding is based on the genetic data obtained recently. Accordingly, fungi have been assigned a separate kingdom along with the plant kingdom and animal kingdom.
Lightning bolts are electric discharges that originate in the clouds during a storm and travel to the earth’s surface. About 100 lightning bolts strike the earth every second. One bolt can contain up to one billion volts of electricity.

The earth is divided into three layers: the upper crust, the middle mantle and the innermost core. The upper crust is made of solid plates, called tectonic plates. Some plates are under the ocean too. The mantle is semi solid and the tectonic plates slide over the mantle, causing an earthquake. Every year over one…

Every person, including identical twins, has a unique eye and tongue print along with their finger print. Tongue prints are as distinctive as eye and finger prints. The technique of biometry is being used to identify individuals using the uniqueness of the iris. Nowadays, tongue prints are also being considered for biometrics, since tongues are…
