In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is
Agata [3.3K]

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.

How do phagocytes protect the body
Olin [163]

1) pathogen enters body and releases chemoattractants

2) a phagocyte/macrophage is attracted by these chemicals

3) the phagocyte engulfs the pathogen using its pseudopodia

4) the membranes of both organisms fuse forming a phagosome

5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome

6) these enzymes digest the pahogen (hydrolyse the bonds)

7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)

during reabsorption of water in the proximal convoluted tubule, what causes water to diffuse from the lumen into the interstitia
castortr0y [4]

Water diffuses from the lumen into the interstitial space during the reabsorption of water in the proximal convoluted tubule due to an increase in the interstitium's osmolarity.

Reabsorption is the process by which water and solutes from the PCT are injected into the blood. From the  proximal convoluted tubule, the solutes and water go to the interstitium before entering the peritubular capillaries. The majority of the solutes and 99 percent of the water filtered by the nephron must be reabsorbed; all of these chemicals were "absorbed" in the digestive tract. The peritubular and vasa recta capillaries return reabsorbed fluids and chemicals to the circulation.
