<h2>The correct answer is explained below:</h2>

Explanation:

  • According to the given question,
  • For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
  • For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
  • The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
  • Hence, the genotype of Sam must be BbGg.
  • Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
  • The gametes produced by Sam are: BG, Bg, bG, bg.
  • The gametes produced by Carole are: bg.
  • Mating them we get,

           BG                    Bg                   bG                       bg

bg      BbGg               Bbgg               bbGg                   bbgg

  (Black/ Green) (Black/ White) (Orange/Green)  (Orange/ White)

  • The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
  • The phenotypes (Eye color/ Skin color) obtained are in the following ratio:

(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1

Histamine increases blood flow and vascular permeability. This would account for all of the following changes that occur during
AnnZ [28]

Histamine inhibits the chemotaxis which is the movement of cells along the gradient.

Histamine:

It is a neurotransmitter that is released by the mast cells in response to an allergen that causes an allergic reaction. It is responsible for redness of the inflamed area, heating, movement of leukocytes, and defense proteins to the site of injury. Histamine is responsible for vasodilation and increased permeability. The immune cells move to the site of injury and cause the flow of blood to the injured site. It plays an important role in allergic and hypersensitivity reactions. Histamine is also responsible for gastric secretion, smooth muscle contraction, and itching.

Phantasy [73]
Since there are no choices, it will be difficult to answer your question.
But let's say these are the choices:

A. in a separate column after the column of data values
B. in parentheses, in the title of the table
C. in the headings of columns that list the data values
<span> D. in a note next to an asterisk, below the table 

Answer – C (In the headings of columns that list the data values)
 In a data table, units of measurement should be indicated in the headings of the columns where the data values are listed. This shows that the indicated unit applies to all the data values listed in the column.</span>
