Options

  1. AWhat causes blood cells to swell when placed in water with less than 0.9% salt concentration?
  2. BWhat causes blood cells to swell when placed in water with less than 0.9% salt concentration?
  3. CWhat causes blood cells to swell when placed in water with less than 0.9% salt concentration?
  4. DWhat causes blood cells to swell when placed in water with less than 0.9% salt concentration?

Correct answer

A. What causes blood cells to swell when placed in water with less than 0.9% salt concentration?

Step-by-step solution

As we know that, in case of p−np-n junction diode, there is no or very less movement of charges in the depletion region. ∴\therefore Current is least in depletion region. So, graph of charge density versus distance will be as shown below The curve between charge density and distance r near a p - n junction is best represented by
