No 2 people in the world are "exactly alike", so the odds would be 0% chance.    Twins, might be closer in alike-ness, but they still aren't "exactly alike".   Hope this answered your question.
 
        
             
        
        
        
1.	Evaporation is the escape of water molecules from their liquid phase to gas phase that go up into the atmosphere. Evaporation can occur anywhere where open liquid water is exposed to sunlight or any other source of energy. Transpiration, on the other hand, is the loss of water (by evaporation) from plants through the stomata. Evaporation and transpiration move water from the biosphere to the atmosphere. 
2.	Condensation is the return of water molecules from gaseous phase (vapor) back to liquid form. Precipitation, on the other hand, is the coming down of condensed water from the atmosphere to the earth (biosphere), which is a significant part of the water cycle. 
3.	Exchange pool is the pool from (or approximate amount) which water or other elements are shared (back and forth) between different spheres (such as biosphere, atmosphere, and hydrosphere) in a cycle. A reservoir on the other hand is analogous to a ‘container’ that holds large masses of water or other elements such as a lake and the atmosphere. 
4.	The answer is No. because, today’s waters, due to increased pollution from industrialization that spews a lot of pullutans into the atmphere, ae contamiated. The water that precipitates is tainted by gases such as sulphuric dioxide tha makes it acidic. The water also gets polluted by other pollutants in the atmpshre and biosphere and hence become a health risk to animals and humans that drink it.
        
             
        
        
        
El Niño as evidence of potential dangers of global warming to marine ecosystems
Explanation:
El Nino, an abnormal type of weather pattern, causes huge climatic variations globally by bringing floods in one region and drought in another region. These extremely changing patterns in weather can damage human life, agriculture, air quality, natural ecosystems, etc all of which might lead to global warming.  
El Nino effect is a serious potential danger to the marine life. This causes variations in the sea surface temperature, ocean currents, and upwelling patterns. Due to this, many marine organisms either migrate to newer places or do not survive the change. 
Due to this, other sea animals depended on them also are depleted of their food source. El Nino also impacts the structure of coral reefs causing coral bleaching which in turn affects the marine life.
