Galveston is considered a barrier island. What does a barrier island do?

The barriers of Galveston Island and Bolivar Peninsula protect the estuary environment from high energy wave action from the Gulf, and maintain moderate salinities. The shallow bays provide excellent habitat for grass beds and salt marshes.

Explanation:

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.

the main objectives of the progressive movement were eliminating problems caused by industrialization, urbanization, immigration, and political corruption.
