The term applied when water passes through a selectively permeable membrane from an area of high to low concentration is called osmosis. Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.
he answer is because <span>samples of air taken over erupting volcanoes shows that volcanoes
contribute a small amount of chlorine in the stratosphere compared to CFCs. Volcanic
eruptions account for a large instability of chlorine from land to the
atmosphere on a yearly basis. This is in addition to chlorine that enters the
atmosphere from sea spray, industrial processes and biological gases which are
from CFCs. All of these inputs happen near or at the base of the atmosphere. Very
little of the material emitted from volcanoes makes it up into the upper
reaches of our atmosphere which is the stratosphere where it could touch the
ozone layer. However, most of it is believed to be deposited lower down which
is in the troposphere, where it then rained out back to the surface of the
earth.</span>
Answer: The gasoline
Explanation: Gasoline is potential chemical energy because it is only used when the car is in use. It becomes kinetic when the car is on.
Service improves society, impacting the helpers as well as those needing assistance. It means being an active participant in one's community, taking action where it can be of benefit. Every person should make it a priority to serve at least two hours per week. It's an extremely important civic responsibility that is invaluable to citizens most in need. Service creates improved communities where people care about each other.
