Which of the following is NOT a prediction arising out of Wilson-MacArthur's -Theory of Island Biogeography?

#SCPH06 I Botany
  1. The number of species on an island should increase with its size/area.
  2. The number of species should decrease with increasing distance of the island from the source pool.
  3. Composition of species should be same over time
  4. Species richness on an island should be related to its average distance to the neighbouring islands

The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration. Phosphate import depends on a pH gradient across the membrane—more acidic outside the cell than inside the cell. In this bacterial cell, phosphate transport is an example of:

In some cells, there are many ion electrochemical gradients across the plasma membrane even though there are usually only one or two proton pumps present in the membrane. The gradients of the other ions are most likely accounted for by:
