Answer:
Carbon dioxide is released when fossil fuel is burned in the atmosphere. The fossil fuels are made of hydrocarbon and once it is burned in air carbon dioxide is released into the environment.
Carbon dioxide is one of the most important gases present in the atmosphere which constitutes of about 95 per cent of the the whole atmospheric gases. 
Carbon dioxide is one of the main green house gases that helps in the absorbing heat from the atmosphere. It makes the temperature suitable for the organism to live on earth.
Carbon dioxide is a waste product of cellular respiration which is released inside the body an is expelled into the outer atmosphere.

DNA ligases close nicks in the phosphodiester backbone of DNA. Biologically, DNA ligases are essential for the joining of Okazaki fragments during replication, and for completing short-patch DNAsynthesis occurring in DNA repair process. There are two classes of DNA ligases.
        
             
        
        
        
Their reproductive isolation from each other is complete: False  
They are unable to produce hybrid offspring upon interbreeding: True  
They shared a common ancestor recently in evolutionary time: False  
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.  
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
