I would go with B .
Hope this helps yaa!
The era of piracy began in the 1500’s and faded by the 1830’s. Their presence was consistent in the Caribbean from 1623-1638 which ended due to navies of Western Europe and North Americans combatting the pirates. Pirates were most successful from 1660-1730’s. Particularly during the 1600’s, maritime technology began innovation. Trading traffic increased, which for pirates meant more ships to ransack and give rise to their piracy. By the 1690’s, pirates began a route they named the “Pirate Round.” They would sail from the Indian to the Red Sea, searching for trade ships deploying from India. 1718 was the beginning of the end for the “Golden Age of Piracy.” Two years later, in 1720, the English captured famous pirate Jack Rackham and his two female shipmates. In 1722, the wealthiest pirate known had died. His name was Bartholomew Roberts. By 1730, this era had ended.
Answer:
Option (A)
Explanation:
A population density map is used to define as a map that shows the presence of a number of the population existing in any particular area. It directly reflects the dispersion of people that are mainly affected by environmental factors. This includes the variable amount of natural resources present in that area, the type of climate prevailing, the topography of the area and the availability of water resources.
The places which are rich in resources and low lying areas, with plenty of water resources and moderate type of climate are comprised of high-density population. On the other hand, the places which are highly elevated, lack of resources and extreme cold and hot climate are comprised of a lesser population.
Thus, the correct answer is option (A).
Answer:
Correct answer is (a). Assimilation of immigrants into the existing population.
Explanation:
The frequency distribution will not change from generation to generation once a population is in Hardy-Weinberg equilibrium. However, on assimilation of immigrants into the existing population, the equilibrium will definitely change.
Answer: If water is the transport medium of sediment, the grain size sedimentary deposits most closely indicates:
(B) average velocity of the water from the time of erosion until deposition.
Explanation: Here, the average velocity of the water determines the sorting of the grain size.
If the average velocity is high like that of the beach, the grain size will be well sorted.
But if the average velocity is low like that of a stream, it would be poorly sorted.
