Answer:

Water is polar and oil is nonpolar so the substances won't mix.

Irina18 [472]
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.

netineya [11]

Answer:

Cell Z has the greatest solute concentration

Explanation:

  • The water moves from higher potential to lower potential.
  • More the solute concentration in solution the lower will be water potential.
  • External mechanical pressure increases the water potential.

Cell Z has more solute concentration, So it require more external pressure to equalize its internal water potential with external water potential for stopping the movement of water from high potential to lower potential.

<em>Remember the maximum potential of water is zero at standard temperature and pressure.</em>
