Answer;
Acid rain is mostly a problem in the Northern Hemisphere.
Explanation;
This can be attributed to the fact that the area has a large, densely populated cities and a concentrated number of industrial and power plants in an area. These factors contribute to acidic gases in the environment such as sulfur oxide, nitrous oxide, which mix with rain water to form acidic rain. Additionally, prevailing wind direction which brings with it the pollution from the midwest to the north east.

Explanation:
Answer:
See below for answer
Explanation:
<u>A. 200 mOsM NaCl</u>
This solution is hypotonic to the red blood cell (RBC) with penetrating solute. The RBCs will swell up and burst because the water will move into the cells.
<u>B. 400 mOsM urea</u>
This solution is hypertonic to the RBCs with non-penetrating solutes. Water will leave the cells via osmosis and the cells will shrink and appear shriveled.
<u>C. 100 mOsM urea plus 200 mOsM NaCl</u>
This time both penetrating and non-penetrating solute is present. The solution is isotonic to the RBCs and although there will be movement of water between the cells and the solution, there will be no overall change in the concentration of water for each and no change in appearance of the cells.
<u>D. 300 mOsM urea</u>
The RBCs will not lyse nor shrivel as again the solution is isotonic to the RBCs.
The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.
<h3>What is se_xual selection?</h3>
The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.
Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.
Se_xual selection can be considered a special type of natural selection that acts at an individual level.
