#Question id: 13216

Which statements is INCORRECT about this figure?


#Unit 6. System Physiology – Plant
  1. If the concentration of potassium chloride is higher in compartment A ([KCl]A > [KCl]B), potassium and chloride ions will diffuse at a higher rate into compartment B
  2. If membrane are more permeable to K+ tham to Cl-,  K+ will diffuse out of the cell (compartment A ) faster than Cl–, causing the cell to develop a negative electric charge with respect to the medium
  3. Diffusion of K+ would carry charges across the membrane until the membrane potential balanced the concentration gradient, Transport would then be at equilibrium, even though the concentration gradients were unchanged
  4. If membrane are more permeable to K+ tham to Cl-,  K+ will diffuse out of the cell (compartment A ) faster than Cl–, causing the cell to develop a positive electric charge with respect to the medium

#Unit 10. Ecological Principles

You observed the two species of barnacles, species 1 and species 2, occupy upper and lower strata of intertidal rocks, respectively. Only when species 1 was removed by you from the upper strata, species 2 could occupy both the upper and lower strata. From the choice given below what would be your inference from these observations.
