olganol [36]

Answer:

Explanation:

Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers

Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.

Staphylococcus epidermis appears _________, whereas escherichia coli appears _________ after the gram stain.
BigorU [14]

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.

Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.

Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.

Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.

Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.

The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.

In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle
Neporo4naja [7]

Answer:

64

Explanation:

Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation

p² + 2pq + q²

where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,

F of homozygous ( featherless legs) = q²

F of heterogyous ( carrier of featherless allele) = 2pq

F (q²) = 128/200 = 0.64

q = √0.64 = 0.8

and p + q = 1

p = 1 - 0.8 = 0.2

2pq = 2 × 0.2 × 0.8 = 0.32

number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
