<h2>The correct answer is: B.</h2>

Explanation:

A variety of species become threatened or endangered due to various natural and anthropogenic factors.
Natural factors like climate change, global warming, flood, volcanoes, forest fires, avalanche, earthquake, tsunami etc cause the death of many species of organisms and often cause the extinction of several endemic and rare species.
Man-made factors like habitat destruction, mining, quarrying, deforestation, poaching, etc also has similar impact on species diversity.
Conservation of animals can be defined as the procedure adopted to promote the well being of different species of animals such that they can survive and reproduce to maintain their existence on earth without getting threatened, endangered or extinct.
A Threatened species can be defined as the one which has a high probability of becoming endangered in the near future.
An Endangered species can be defined as the one whose population has reduced to such an extent that the probability of the species to become extinct in the near future becomes exceptionally high.
An Extinct Species can be defined as the one whose last surviving individual has died. The ability of such a species to breed and recover its population gets lost much earlier.
Conservation program carried out for the preservation of a particular animal species includes the protection of their surviving habitat, breeding habitat and also their hibernating habitat.
A particular habitat can be occupied by multiple species of organisms which occupy different ecological niches.
Therefore, conservation of the habitat of a particular species of organism will simultaneously cause the conservation of other species present in the same habitat.
Hence, this would indirectly cause the conservation of other endangered species.

sergeinik [125]

*Sickle cell disease is a constitutional corpuscular hemolytic anemia related to an abnormal structure of the globin chain. It is an autosomal recessive disease, which means homozygosity is necessary to fully express the illness.
*It corresponds to the synthesis of an abnormal hemoglobin, HbS, which is different from normal Hb (HbA).

*The S allele (located in the chromosome 11), responsible for the anomaly, is especially widespread in the African continent, it is also found in other regions of the Mediterranean.

*Mutation GAG to GTG leading to the substitution Glutamine by a valine in position 6 of the chain of the globine.</span>
