gene flow or migration between two populations will help maintain similarities between the species, therefore preventing (or slowing down) the process of speciation. and when the environment changes rapidly, this can cause an overall decrease in population size because of a failure to adapt adequately to environmental changes. i hope this helped <3
 
        
             
        
        
        
The melting of the ice caps makes Earth warmer because less solar energy is reflected due to loss of Albedo 
        
                    
             
        
        
        
Probably the U.S. Environmental Protection Agency also known
as the EPA.  They are charged with
protecting people and the environment by enforcing regulations that prevent
pollution.  If they find any violation
committed they can impose sanctions and fines as well as imprisonment depending
on the nature of the offense.

The allele would be called codominant
When a dominant and recessive allele exist in an organism, only the dominant allele will be expressed. Dominant allele always mask the recessive because the gene code a protein while recessive gene doesn't. When both gene code a protein, they will be codominant and both gene will be expressed. The result could be a mixed effect. In this case, the purple is mixed color of red and blue.
