Simple answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.
More in depth explanation:
Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.
Hope this helped :)

Explanation:
behaviors of people as well as the rapid advances of technology, amounts and the composition of MSW have been also changed. In a study carried out by the European Environmental Agency to study the per capita annual MSW produced by 32 European countries during 2001–2010, they found that this waste increased in 21 countries, and was decreased in 11 countries. The study also studied the amount of wastes of 26 countries between 2001 and 2008; they found that these amounts decreased in 6 countries. Thus, the amounts and characteristics of the wastes varied from country to another country, as well as from region to region even within the same city according the mentioned factors including the usage habits of people
 
        
             
        
        
        
Hello there! 
The most plausible answer here, I believe, would be Polymerase. 
Polymerase is responsible for joining nucleotides to create new strands of DNA, or, replicating. Hope this helps and have a nice day.
