This can cause other organisms that relay on this specific aquifer to find other sources of water or die. 
<span>An aquifer is actually an underground layer of water that contains permeable rocks, gravel, sand etc. the water can be brought to the surface by making a water well. Hydrogeology is the study of aquifers and the way of water flow in the aquifers. The depth of the aquifers differs from area to area and the aquifers that are closest to the surface are used for drinking and irrigation purposes. </span>
        
             
        
        
        
Answer:a) decreased chromatin condensation
Explanation:
During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes. 
 The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.
Chromatin condensation is driven by condensins and interactions between histones. 
Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation. 
Chemical manipulation as stated above is decreases the rate of chromatin condensation.
 
        
             
        
        
        
Answer: D.) This gene sequence ensures transcription of arabinose genes only
when arabinose is available, saving the cell from expending energy
