<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

yaroslaw [1]
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.

What means RNA and it shape in the biology
MaRussiya [10]

The Answer is ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.

I hope this helps you:)

How is the speed of light affected as light passes at an angle from air to water
Liula [17]
They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
