The black death contributed to the growth of the arts by. decimating the population, leaving the survivors wealthier. giving artists a universal subject to depict. strengthening the control of the church. forcing people to spend more time indoors, where they could work on art.

The Black Death was a pandemic event in the medieval period. This had led to a massive death toll of 75-200 million people all over Europe in 1346-1953. This pandemic was caused by a pathogen called  Yersinia pestis.

A) Decimating the population, leaving the survivors wealthier

I took the test and A was correct!

there is no photo, therefore i can not answer your question.

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.
