Because since developing countries are still growing, when they finally get to the level of some more advanced countries the country as a whole feels a "greater growth"
 
        
                    
             
        
        
        
A. Neutral water 
Less than 7 is acidic (which has 6 letters, 6< 7)
More than 7 is alkaline (which has more than 7 letters). Alkaline = basic 
7 is neutral
 
        
                    
             
        
        
        
There are many benefits provided by biodiversity. It can be in our biological resources, ecosystem services and also social benefits. The three social benefits provided by biodiversity would be the following:
1. Research, education and monitoring 
2. Recreation & tourism 
3. Cultural values 
Explanation:
Biodiversity is “the variability among existing animals from all causes including temporal, marine and other aquatic ecosystems, and the environmental complex.
Pollinators, including bees and butterflies, contribute meaningful environmental and economic advantages to agricultural and essential ecosystems, including adding heterogeneity and productivity to food crops. As many as one-third of the world's food production relies directly or indirectly on insect pollination.
 
        
                    
             
        
        
        
Answer:
Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.
Explanation:
In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers. 
These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template. 
These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations 
It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.
