Answer:
The question is incomplete, it lacks the main questions, those questions are:
a. What is the genotype for black chickens?
b. What is the genotype for white chickens?
c. What is the genotype for erminette chickens?
Explanation:
This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.

Answer:
Lactic acid fermentation occurs in the cytoplasm of the cell.
It's a form of anaerobic respiration, and occurs when oxygen is unavailable in animal (muscle) cells and in some bacteria.
Answer & explanation:
Non-native species may be animals, plants or microorganisms introduced into an ecosystem of which they are not originally part, but where they adapt and come to dominate, harming natural processes and native organisms.
When a new species is introduced into an environment other than its own, it may compete with others, prey heavily on some species, over-breed and even cause disease.
Therefore, it can be concluded that this action may cause the destruction of some species, directly affecting the balance of that ecosystem.
