Why did the Native American Indian population change so much ?

Tragically, when the Europeans came to the Americas, they brought diseases that the natives were not yet exposed to. Therefore, many Native Americans died from these diseases. Those who survived the diseases were often mistreated by the Europeans. Some were made slaves, others fled west, etc.

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 !

briefly explain support for the argument that the articles of confederation succeeded in guiding the us through its first decade
