Why is the ringing of bells an important custom of mexican independence day?

The ringing of bells in an important custom when Independence Day is celebrated in Mexico as it constitutes the manner of commemorating the so-called Cry of Dolores.

The Cry of Dolores was an event that took place in 1810 in the Mexican city of Dolores. A priest called Miguel Hidalgo y Costilla, after ringing the bell of his church, delivered the pronunciamiento. This is a term Spanish that is used to refer to a call to arms. Those bells and the subsequent pronunciamiento triggered the Mexican Independent War.

with my recent question

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 !
