Answer:
When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.
As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
The Pa. Fish and Boat Commission wants acid rain gases reduced by 40%
<h3>What is Acid Rain?</h3>
Acid rain is formed by the precipitation of acid in the form of rain due to reaction of two atmospheric pollutants like oxides of nitrogen and Sulphur with rainwater.
The deposition of acids can occur either wet and dry way.
In wet deposition the precipitation removes acids from the atmosphere and place them on earth surface.
In dry method the deposition of gases and pollutants in the form of dust and smoke.
Man-made cause is the emission of gases from industries or by natural way like lightning which release nitrogen oxides and volcanic eruptions release Sulphur oxide.
The pH value of acid rain is around 5.7.

Explanation: I suggest: A freeze occurs when the temperature drops below 32 degrees, and frost can happen when the air temperature (which is measured about six feet above the ground) is up to about 36 degrees. If part of your yard is lower than the rest, it’ll probably be coldest there since cold air is heavier and sinks down.
