A protective layer that shields the surface from lethal ultraviolet light is found in the layer of the atmosphere known as the Stratosphere.
Therefore, the correct answer is option C for this specific statement.<span />
Explanation:
Iodophor -
Iodophor is a complex of iodine , with solubilizing agents , such as the povidone , surfactant .
And forms a water - soluble material which can release free iodine in the solution phase .
Dilute form of iodophor is used by winemakers and brewers to sanitize their equipment and bottles .
The major advantage of iodophor over other is that , it increases the stability of iodine .
I believe the statement would be that, A magnetic field created by the electric current causes the compass needle to move.
An electric current through a conductor creates a magnetic field,such that when a charged particle such as an electron, proton, or ion is in motion, magnetic lines of force rotate around the particle. Since current moving through the wire consists of electrons in motion, there is a magnetic field around the wire, which causes the compass needle to deflect.
Answer: Possession of Valves
Explanation: Veins possess valves which ensures that blood flows in only one direction. Valves helps blood to flow back to the heart against gravitational force.
Arteries don't have valves because the pressure originating from the heart is capable of causing the blood to flow in one direction.
