  • Brain death: is the legal definition of death. It is the complete and irreversible stop of all brain functions. This means that as a result of severe aggression or severe brain injury, the blood that comes from the body and supplies the brain is blocked and the brain dies.
  • Agonal phase: occurs with the realization of the preceding events when life is about to break free of the protoplasm, because the protoplasm cannot sustain it for long.
  • Clinical death: is defined by the cessation of electrical activity in the brain, resulting in irreversible and total loss of neurological activity in the brain and brainstem. When doctors officially declare a person's clinical death, it means there is no cure or return to recovery.
  • Mortality: It is the condition of being mortal, therefore, of being susceptible to death. However, the term mortality is in most cases related to the statistical studies applied on populations. So mortality appears as a number that seeks to establish the number of deaths over a given population.

<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.

Which of the following routinely occurs in both eukaryotic and prokaryotic transcription?a. the RNA polymerase undergoes abortiv
Salsk061 [2.6K]

Answer:

a. the RNA polymerase undergoes abortive initiation prior to promoter clearance

Explanation:

In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.

In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.

Most bacterial RNA transcripts do not undergo splicing.

The nucleosome is the basic unit of chromatin repeat in eukaryotes.

During reduction, PGA reacts with ATP and NADPH. What does ATP contribute to the reaction?
ivann1987 [24]

Answer:

D. Phosphate group

Explanation:

When oxygen is added to a carbon chain, one of the predicted outcomes is the addition of a phosphate group to ADP, which generates ATP. Furthermore, during cellular respiration, biological energy is converted to generate adenosine triphosphate, which is used by the cells for energy.
