Answer:
VDF= Vm- Veq.
Where VDF = Electrochemicall driving force
Vm=Membrane potential
Veq.=Equilibrium potential for the ion of interest
Ideally when VDF=0 at Electrochemical equilibrium, i.e. Vm=Veq, there is no net movement of ions across the membrane.
So, Answer is (D) This scenario is impossible.
The movement of substances across the cell membrane either into or out of the cell
Answer:
Sandy soil or Coarsely Textured Soils
Explanation:
All soils that have high amount of sand (sandy soil) or the one which have coarse texture are poor in organic matter retention and thus have low organic matter content. These soils are highly permeable and thus are unable to hold soil moisture and organic matter.
On the other hand they have rich salt content because they are in touch with salty water of sea or oceans.
