Difference between A.C and D.C |
|
| Answer» | \tAC can carry and safe to transfer longer distance even between two cities, and maintain the electric power.DC cannot travel for very longer distance. If does, it loses electric power.The rotating magnets causes the change in direction of electric flow.The steady magnetism makes the DC to flow in a single direction.The frequency of AC is depended upon the country. But, generally the frequency is 50Hz or 60Hz.DC has no frequency of zero frequency.In AC the flow of current changes it direction backwards periodically.It flows in single direction steadily.Electrons in AC keep changing its directions – backward and forwardElectrons only move in one direction – that is forward.\t | |

Machensum of opening closing of stometa |
| Answer» Mechanism of opening and closing of stomataOpening of stomata: Solutes from neighbouring epidermal and mesophyll cells enter the guard cells lowering its osmotic potential and water potential. This lowered water potential and osmotic potential will allow movement of water into guard cells from neighbouring cells. Guard cells become turgid due to water accumulation in them which results in the opening of the guard cells.\xa0Closing of stomata: As the somata open the solute concentration is reduced. This makes the water from the guard cells to move away into neighbouring cells. Now, guard cells becom flaccid with no water. They collapse against each other and result in the closing of stomata.\xa0 | |
