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.
        
             
        
        
        
Answer:True 
Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :
1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing 
2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing. 
 
        
             
        
        
        
E. coli belongs to the genus Escherichia 
Taxonomically, <em>Escherichia coli </em>is categorized as belonging to the phylum Proteobacteria, class Gammaproteobacteria, family Enterobacteriaceae, order Enterobacteriales, and genus Escherichia (named after its discoverer, Theodor Escherich).
- Escherichia coli (E. coli) are typically found in warm-blooded organisms' lower intestines. The majority of E. coli strains are not harmful, but some can seriously poison food.
- A  Shiga toxin-producing E. coli (STEC) is capable of causing severe foodborne illness.
- Raw or undercooked ground meat products, raw milk, and fecal contamination of vegetables are the most common causes of STEC outbreaks.
- The illness is usually self-limiting, but it can progress to a potentially fatal condition like haemolytic uraemic syndrome (HUS), especially in young children and the elderly.
