The replacement rate is the level at which a population remains stable.
<span>Replacement rate (level) is the fertility rate and represents the average number of children born per woman at which a population<span> exactly replaces itself from one generation to the next (without migration). More precisely, </span>it is the amount of fertility needed to keep the population the same, from generation to generation. As a result of the total <span>fertility rate,</span><span> there will be no increasing or decreasing of the population, it will be stable. </span></span>
<span>(1) </span><span>Many assumptions gave rise to a mystery on Eastern island –why it has so slow growth of human population during the old times. The most common assumption read is that leader Rapa Nui, had greedily used up all the island’s resources leaving nothing for people to use and eat. The reason also why they fall to war and cannibalism. </span>
<span>(2) </span>Other factors that limit the growth population of an organism are:
<span>· </span>density-dependent factors like food supply, disease and pollution and density
<span>independent factors like freezing, weather, and drought. </span>
Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.
Your best bet is most likely going to be B
A Chromosome holds part or all of the genetic material of an organism. It also includes packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.
So yes your best bet is B.
Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.
Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.
On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
