Certain alleles may cause serious diseases in a given environment but they may also be beneficial in different environmental conditions. It is a principle of natural selection.
<h3>Natural selection and alleles</h3>
Natural selection refers to the differential survival and reproduction of an organism in a given environment.
Certain alleles such as the allele of sickle cell disease show an evolutionary advantage in specific environmental conditions.
This allele is lethal in homo-zygous individuals, thereby tending to be eliminated from the population.
However, in regions where malaria is endemic, the presence of carriers individual having the sickle cell allele is advantageous to prevent this disease.

<span>A cell is the most basic form of
life. It is what most of the organisms are made off. For the organism to
function, the cell must also function. It has organelles too that helps
functions what the microorganisms need. A leaf cell contains chloroplasts that
animal cells and animal cells do not have.
The chloroplast is where the photosynthesis happens. It needs sunlight
for the process of photosynthesis. Notice that the leaf has a broader surface
area to enable them to be exposed to the sun.</span>
<u>Function: -</u>
The advancement of the central nervous system, the growth and operation of the reproductive organs, and also the metabolism and blood sugar level, are all regulated by the endocrine system, which is made up of all the various hormones produced by the body from conception and via adulthood and into old age.
Metabolism- The alterations in an organism's or a cell's chemistry. These modifications generate the ingredients and energy that cells and organisms require to develop, procreate, and maintain health. Anabolism and catabolism are components of metabolism.
Hormones- Chemicals called hormones function in the body as messenger molecules. They are created in one area of the body and then go to other areas where they assist regulate how cells and organs function.

Answer:
B. Nuclear energy
this type of energy splits nuclei or combines them.
Because by damaging capsids, there is no place for the bad DNA to be stored. So the drug destroys the DNA so no more of the virus can be stored in the body.
