<u>Answer</u>:
No, speciation doesn’t occur in specific characteristics and predictable manner.
<u>Explanation</u>:
Speciation means creation of a new kind of plant or animal. When a particular species separates from its members of species and develops its own characteristics, speciation occurs.
There are different types of Speciation. In allopatric speciation, species separate due to geographical conditions like waterways or mountain range and evolve into separate species. Whereas in Sympatric speciation, species evolve into separate ones without any change in geographical conditions. Other types of speciation are artificial, peripatric and parapatric type of speciation. So, these changes are neither specific nor predictable.

Option 2, Salmon
Explanation:
Large fishes such as shark and sword fish have higher level of mercury. This fact can be explained by the concept of bio magnification in which an individual lying at a higher trophic level in a food chain gets accumulated toxin and hence possess the highest amount of toxin in a given food chain. Small fish such as salmon will have the lowest amount of mercury as they lie at the lower level of a food chain and hence possess a small amount of toxin
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.
