Answer:
one that has an unstable nucleus
Explanation:
An isotope is defined as a chemical variant present in an atom with different number of neutron but same number of protons.
Radioactive decay is the sudden breakdown of an atomic nucleus allowing matter and radiation to be emitted from the nucleus. A radioisotope with unstable nuclei undergoes radioactive decay because they do not have adequate binding energy to keep the nucleus together. there are four types of Alpha, Beta, Gamma Decay and Positron Emission.
Hence, the correct option is "one that has an unstable nucleus"
In the case of the Bombina frogs, the evidence that hybrid zone
stability is occurring was the consistent pattern from annual to annual of declining
frequency of yellow-bellied toad alleles with distance from the edge of their
range. This is a clear evidence that hybridization is taking place yearly in
the Bombina frogs.
Based on the graph, it can be concluded that the population is increasing rapidly because of the youth of the population.
<h3>What is population?</h3>
The population of a species is the number of organisms of the same species found within a given habitat.
Population graphs are used to describe the trend in the population of a given species of organisms.
The factors that affects population growth of a country include:
- fertility rates,
- mortality rates or life expectancy,
- the initial age profile of the population, and
- migration
Given the population graph of the country, the conclusion can be drawn is that the population is increasing rapidly because of the youth of the population.
In conclusion, the higher the fertility rate the faster the population growth.

A scientist constructs a graph to show the age structure of the human population of Country Y. The graph is shown here. What conclusion is supported by the graph?
The population is increasing rapidly because of the youth of the population.
Hi there!
The best possible scenario for the giraffes with longer necks to survive would be one in which all the lower leaves somehow disappear! This would mean only giraffes with longer necks can eat therefore those will have a better chance of surviving. Luckily the answer that fits that perfectly would be...
D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.
