Answer:
The correct answer is- osmosis.
Explanation:
Osmosis is the name given to the process by which water crosses a selectively permeable membrane. In osmosis water and other solvent move from a region that has a low concentration of solute to a region that has a high concentration of solute through a semipermeable membrane.
The osmosis of water across the cell is necessary to maintain the osmotic pressure of the cell by equalizing the concentration of solute in and out of the cell. Osmosis process does not require energy so it is a passive transport.
Therefore through osmosis water moves in and out of the cell through the selective membrane so the right answer is- osmosis.
Answer: C) They can contain contaminants that can enter the air during storms or high winds.
Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).
B is wrong because water contamination does not directly relate to respiratory health.
D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).
Hope this helps :)
