What are some advantages and disadvantages to 17 countries sharing the same currency? (euro) ? ?

the advantages are you don't have to transfer the money into what ever the local currency is but the disadvantages are if the euro was to plummet in worth those countries would go bankrupt and face economical and political instability

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 !
