100% because the genotypes for the girls are FF and the man's are ff meaning all children will be Ff with the freckles trait
Humans add substances to the water
Acids are solutions/substances that tend to break off to make a hydrogen (H+) ion when placed in an aqueous solution; i.e. solution with water as its solvent.
Bases, on the other hand, produce a hydroxide ion (OH-) when placed in an aqueous solution.
Thus, by definition, we can safely assume that a solution containing a large number of hydroxide ions is considered a base.
If you are unclear about this, or still need help, please feel free to ask me further. Thank you.
Answer:

Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:

The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:


Represent as percentage:

Ammonification is the correct answer for your question, hope this helped :)
