The part of human body that do the same job as wires and circuits is our brain . With enormous amount of nerves and computing cells , our brain has the capacity to do work like circuits . ,Not equal to them , but to some extent its quite complex
1. peripheral nervous system
2. synapse
3.nerve impulse
If i am not mistake i believe it is nuclear
The Sun is located
at the center of our Solar System, at a distance of about 150 x 106 kilometers from
Earth. The Sun produces solar heat energy. This energy travels through space in the form of electromagnetic
waves. The process of heat transfer is known as radiation.Before reaching the sea-level the sun's rays have to pass through the whole thickness of the atmosphere.
So, the first surface that has the potential to come into contact with solar radiation are the clouds.
During active transport proteins powered by ATP move substances up a concentration gradient. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
