Answer:
please post only one question mate.....
Explanation:
26) A solenoid is a coil of insulated wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron which produces magnetic field when electric current passed through it. It is a electromechanical device. Devices of this kind can be used as electromagnets, as inductors in electronic circuits etc.
27) When the body of Planaria is cut into number of pieces, the each and every body piece can regenerate and results in formation of a complete Planaria. The regeneration of an organism occurs by the process of growth and development The cells of body part which has been cut down gets divides and makes a ball of cells.
