When was the 2nd world war​

1 september 1939 - 2 september 1945

Explanation:

WW2 was from September 1st, 1939 to September 2nd, 1945

Explanation:

I've done some reading on WW2 and even fact checked my numbers, so they're the right dates for sure ^^

secretly cooperate with one another.

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 !
