How did the use of mercenaries by the roman army contribute to the eventual collapse of the empire? Please write it in a paragraph please.

In desperate need of soldiers to help with the invasions, Rome hired mercenaries to defend its borders. According to some historians, many were Germanic warriors who did not feel loyalty to Rome. ... The most evident factor of the Roman Empire's fall was the invasions.

Explanation:

a variant spelling of the word dote (british)

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
