The answer is; greenhouse effect, insulating 
Examples of greenhouse gases in the atmosphere are carbon dioxide and methane. They trap infrared light spectrum emitted from the earth towards space. This trap acts as heat insulation causing global temperatures to rise and resulting in global warming and climate change. 
 
        
                    
             
        
        
        
DNA is made up of the individual units called Nucleotides.
        
             
        
        
        
Behavior is the least affected by the limiting factors.
Behavior can remain constant throughout the conditions but when necessary, adaptations can occur due to the limiting factors that constrict a certain action.

DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG) 
with that, they only come in 3 nucleotide increments.
