Answer:

Nuclear decay rates are constant

Explanation:

Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.

Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.

The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).

<h3>What is speciation?</h3>

Speciation is the evolutionary process in which in populations of organisms come to being or evolve to become distinct species. The biologist Orator F. Cook made some Discovery and term it speciation in 1906when he performed experiment on cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

Therefore, A new island is formed from a volcanic eruption is an event that lead to speciation.

If a point mutation occurs in a body cell so that the original sequence of mRNA of CGA changes to AGA, what will be the likely c
Talja [164]

Hi,

If a point mutation occurs during which  CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.

This is because, both AGA and CGA code for same amino acid called Arginine.

We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism

Hope it helps!:)
