Which technological innovation most contributed to the spread of railroads in great britain?
a. the water wheel
b. the bessemer process
c. the flying shuttle
d. the seed drill

The correct answer is B) the Bessemer process.

The technological innovation that most contributed to the spread of railroads in Great Britain was the Bessemer process.

The Bessemer process allowed the mass production of steel in England. English inventor Henry Bessemer patented the invention in 1856. His invention removed the impurities from the iron by the process of oxidation. This invention gave a great impulse to railroads construction in England that was a key part during the Industrialization years, helping with the transportation of people, goods and all type or cargo that was part of the trade.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
