Answer:
There is no diagram but the needed information has been provided. The answer is:
Part C
Explanation:
The bacteria is a prokaryotic living organism in the domain Bacteria. It is pretty because it lacks a membrane-bound nucleus that houses its genetic material (DNA), instead its circular chromosome is found naked in a region of the cytoplasm called NUCLEOID. The nucleoid region contains the genetic material of the bacterium cell.
Since bacteria reproduces asexually, which does not allow diversity among species, bacteria ensures they promote genetic recombination by exchanging their genetic material in three ways: Transduction, Transformation and Conjugation. This genetic recombination causes them to be better pathogens and improve their resistance. However , since the exchange involves the genetic material (DNA), it is only natural that it involves the region where it is found, which is the NUCLEOID.
The Central Nervous System is made up of the brain and the spinal cord.

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
