the whole process is performed by only this kidney. You can say that there is extra burden on single kidney. Plane can also fly with single engine but its risky. If this single kidney gives up then life of man is in danger. In these patients, diet plan is changed.

Paramagnetism is the form of magnetism that occurs only in the presence of an externally applied magnetic field While Diamagnetism is the property of an object which causes it to create a magnetic field in opposition to an externally applied magnetic field. It causes a repulsive effect.

The invention of the wheel can't be pinpointed to a particular individual but the earliest evidence comes from Mesopotamia in around the 5th millenium BC

How fog forms?
Fog begins to form when water vapor condenses into tiny liquid water droplets in the air. The main ways water vapor is added to the air are: wind convergence into areas of upward motion, precipitation or virga falling from above, daytime heating evaporating water from the surface of oceans, water bodies or wet land, transpiration from plants, cool or dry air moving over warmer water, and lifting air over mountains. Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds.Fog, like its slightly elevated cousin stratus, is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass.
