Answer:
'Cross experiments done by Morgan, illustrating the X-inheritance link of a mutation Thomas Hunt Morgan moved intensely in a program of breeding and crossing miles of fruit flies at New York University in a room that was renamed the Fourth of the Flies. He tried to mutate the flies with various means (X-rays, centrifuges, etc.) .The fruit fly which has 4 pairs of chromosomes. One of those pairs was identified as containing X and Y sex chromosomes. He applied Mendelian principles in flies. Morgan's inheritance study demonstrated inheritance linked to sex, and is one of the first evidences that confirm the chromosomal theory of cross-based inheritance. In 1909, Morgan detected a fruit fly (Drosophila melanogaster) with a strange mutation which he called "white eyes", due to the coloration of his eyes (contrary to normal, which is red). Analyzing this fly under the microscope Morgan discovered that it was a male, and could use it as a stallion so that he could observe how the new characteristic of white eyes would pass from generation to generation.All the offspring of this cross will have red eyes, which He made Morgan suspect that something strange had happened, since the color of the father's eyes could not have disappeared. He decided to take a couple of "daughters flies" and cross them together, just to see what happened. Morgan's surprise was very great, observing that among the "granddaughters" flies only males had white eyes. The problem then was to explain what had happened during the hereditary transmission for the color of the white eyes only the males possessed. .

Explanation:
Genetic information:
Nucleic acids are the molecules that build the code of the genetic information of an organism.
There are two nucleic acids that are used in the repair, reproduction, and protein synthesis process. Those are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
DNA and RNA are the polymers that are made up of monomers called nucleotides.
Double helix:
A DNA molecule is a double helix which is made up of two strands of polymers. These two strands of polymers are complementary to each other but not identical to each one. Hydrogen bonding holds the base pairs of these two strands together.
The DNA base pairs are made up of Adenine, Guanine, Cytosine, and Thymine
Generally RNA does not use thymine, it uses uracil.
RNA is used to direct the production process of proteins by the cell.
RNA is generated by copying DNA.
I believe its B because bees spread pollen but take honey.
