How did immigration to the united states from europe change between 1840 and 1850?

It more than tripled.

Explanation:

Between 1840 and 1850, immigration from Europe to the United States more than tripled, getting to a total immigrant population of 1,713,000, including over 781,000 Irish, 435,000 Germans, 267,000 British, and 77,000 French people. The Irish, German, and Scandinavian immigrants entering during the 1840s and 1850s were part of the second wave of European immigration, that was escaping famine, religious oppression, and political conflicts.

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 !
