Answer 1

1. if you change your child theme, the customization of the parent theme remains there in wordpress cause the parent theme is the same
2. in a child theme wordpress search the file first in the child theme folder, then, if not found, goes to the parent theme (is the same to all files, except functions.php that not overrides the parent theme functions cause is loaded in addition)
3. if you active a child theme takes all the functions of the base themes but with the files in the child theme is like and object that extends another
