Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being.<u> In response to contact with a virus, the</u><u> immune system</u><u> synthesizes specific </u><u>antibodies</u> to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

Answer:
The correct option is D)  They can insert the gene for the protein from plant species Bigous moldkillae into a chromosome in Yummious letus.
Explanation:
Biotechnology can be described as the technology in which the genome of organisms are altered so that organisms with better qualities can be produced. In the scenario discussed in the question, techniques of biotechnology can be used to insert the fungus-killing gene of Bigous moldkillae into the genome of the Yunnious letus. In this way, the Yunnious letus species will become resistant to the fungal infections.

Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
