Which does not describe an impact of railroads on business and industry in the 1800s? a. finished goods could be transported to markets quickly. b. small towns along railroad lines grew into major industrial centers. c. manufacturers could get raw materials more easily. d. the cost of manufactured goods went up.

c. bounced back and forth from worthless to worth a lot and back to worthless

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 !
