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:
The advise I will offer the next scientist about how the laboratorycan beimproved include the following
Calibration of instruments: Instruments which are used in the laboratory should be calibrated so as to reduce errors and inaccuracy during experiments.
Proper labeling of Samples : This helps to give the scientists an idea of where to find samples and to prevent making mistakes in picking the wrong one. This helps to save time and resources in the lab.
Adequate cleaning and waste disposal: Cleaning of the lab and disposal of the wastes helps to eliminate contamination of samples.

Answer:
b is the correct answer ok bro
The solar system is considered a natural system because it was made and controlled by natural forces, meaning, it was never influenced with human creations. It is considered as one of the products of the phenomenon of the physical world. Hope this answer helps you.
Answer:
The cell is in a hypertonic solution.
Explanation:
The solution is hypertonic because the amount of solute(s) is higher outside of the cell than it is inside the cell, so the solvent (e.g. water) would move from the cell to the solution in order to obtain equilibrium between the two.
