Answer:
At heart, all life on Earth uses a membrane that separates the organism from its environment. ... In this regard, water is essential simply because it's a liquid at Earth-like temperatures. Because it flows, water provides an efficient way to transfer substances from a cell to the cell's environment.
 
        
             
        
        
        
Answer:

Explanation:
It is given that 
B is the dominant allele which represents the black color
and b is the recessive allele which represents the white fur. 
B being dominant will result into black color fur for genotype "Bb"
Given - 
Frequency of black fur allele (p) is 
As per Hardy Weinberg's  first law of equilibrium

Substituting the value of p in above equation, we get - 

q represents the frequency for white fur allele
Frequency of white fur phenotype is 

Frequency of homozygous black fur phenotype (BB) is 

As per Hardy Weinberg's second law of equilibrium - 

Combined frequency of homozygous and heterozygous black fur phenotype is
