To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
When the temperature of the air becomes almost equal to the dew point the air becomes saturated and the relative humidity during this condition becomes 100%. If the temperature of the air decrease below the dew point the relative humidity will be 100% or exceeds 100%. This condition, when the temperature of the air decreases below the dew point is called supersaturation but most of the time the temperature of the air will be lower than the dew point.

Secondary structure of protein.
in seconday structure, the polypeptide chain is spirally arranged in linear form.
Teriary structure of protein
In tertiary structure the polypeptide chain is arranged in three dimension.
Quaternary structure of protein
In this structure more than one polypeptide chain are arranged in three dimension forming a globular shape.
