Please find the punnet square to this question as an attachment
F1 generation:
genotype = BW
Phenotype = Erminette offsprings
F2 generation:
genotype = BB (1): BW(2): WW(1)
Phenotype = 1 Black, 2 Erminette, 1White
Explanation:
This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).
According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)
Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:
Genotypic ratio = BB (1): BW(2): WW(1)
Phenotypic ratio = 1 Black, 2 Erminette, 1White
Hey :)
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Hopefully this helped and good luck!!!
Answer:
Substance B is a group of hydroxide ions.
Explanation:
Chemical methods--It includes ion exchange, precipitation, oxidation and reduction, and neutralization.........
Thermal methods--In this, high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them....
Biological treatment-- It is of certain organic wastes, such as those from the petroleum industry by a special method called landfarming
Physical treatment-- It concentrates, solidifies, or reduces the volume of the waste. Physical processes include evaporation, sedimentation, flotation, and filtration....
Limiting factors are what controls the population of an ecosystem. It also limits the kind of organisms that inhabit it. Limiting factors can be abiotic or biotic. Abiotic factors are the nonliving factors that affect the living ones. From the given options above, the only biotic limiting factor is vegetation. The correct answer would be option B.
