<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.

________ marks the end of a gene and causes transcription to stop. ________ marks the end of a gene and causes transcription to
Paha777 [63]

The answer is a terminator or transcription terminator. It is part of nucleic acid sequence that marks the end of a gene in DNA during transcription. This progression intercedes transcriptional termination by giving signals in the newly synthesized mRNA that activate processes which release the mRNA from the transcriptional complex. These processes comprise the direct interaction of the mRNA secondary structure with the complex and the meandering activities of recruited termination factors<span>. </span>

Answer:

The correct option is A. Theories that are related to the evolution of humans from apes will change.

Explanation:

The research from Dr. Katherine will change the theory of evolution of humans from apes because according to the theory of evolution changes in the genetic sequence of apes caused the formation of humans. But Dr. Katherine Pollard's research says that no deletion or addition of genes took place rather the genome of humans and apes is same with certain switches controlling the genome.
