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

You have a white eyed, male fruit fly with vestigial wings and a wild type female known to be heterozygous for both traits. You know that vestigial is located on an autosome. What is the probability that a mating between these two flies will generate a female offspring with vestigial wings and white eyes?
