Reasoning - Its the basic function of requirements for survival of species and organisms.
Answer:
The Sahel has been labeled as one of those regions with the danger of overpopulation. It has been described with adjectives such as semi-arid, hot, dry, windy or sunny.
Sources have it that the G5 Sahel countries which include Mali, Niger, Burkina Faso, Mauritania, Chad will increase from about 84 million inhabitants in 2019 to 197 million in 2050. This projection includes people under 15 years of age which comprise about 50% of the entire population.
The climate itself doesn't seem to deter population growth. What seems to be occurring is sedentarization. This is due to rapid desertification and drought which have persisted for some time.
Explanation:
Sedentarization refers to the choice of a group of people who usually are very nomadic or migratory to settle permanently in a place.
This is usually due to a more favorable weather and topography which supports agriculture.

Answer:
The event that could not be caused by a population bottleneck is increased population size.
Explanation:
Population bottleneck (genetic bottleneck) is a phenomenon that causes a sharp reduction in population size. It is caused by various factors like environmental disasters such as disease, famines, earthquakes, floods, etc or human activities like hunting, genocide, destruction of habitat, etc. These factors reduce the genetic variation in a population and cause smaller genetic diversity in a smaller population. This causes a change in allele frequency (genetic drift) and it leads to loss of alleles. The effects of genetic drift are stronger in smaller populations than large ones. The small population size increases the chances of inbreeding, accumulation of harmful mutations and genetic homogeneity which leads to inbreeding depression.
An example of a population bottleneck is Cheetahs, which suffers a reduction in genetic diversity during their bottleneck. As a result, they have problems in their reproduction and are highly susceptible to diseases.
“Heat of Vaporization” it takes energy to evaporate sweat off of your skin and that energy is heat. As your excess body heat is used to convert beads of sweat and vapor you start to cool down.
