Enzymes are not used in the reaction so usually the enzyme will sort of reset and be ready to use in another reaction . this is because enzymes are proteins and their shape is what they use in a chemical reaction so when the reaction is done the product is released (the reaction) and the enzyme can relax and go back to its normal shape
The two main types of fermentation are alcoholic fermentation and lactic acid fermentation. In an alcoholic fermentation, the main product of this process is ethyl alcohol. Lactic acid on the other hand has lactic acid as its main product. When muscle cells run out of oxygen, lactic acid fermentation would commonly take place.<span> </span>
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

Hypothesis and conclusion
