Answer:
Explanation:
When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.
Such a movement is called Primary Active Transport
The land and the way the heat changes around there
Answer:
The new pressure becomes one third of the initial pressure.
Explanation:
The relation between pressure and volume at constant temperature is given by :

Let new pressure and volume be P' and V' respectively.
V'=3V (given)
So,

Hence, new pressure becomes one third of the initial pressure.
