A:
Normally, when an organization is just beginning, a motion is adopted that a committee be appointed by the chair to draft bylaws (RONR p. 549).
At a subsequent meeting, a motion is made to adopt the bylaws presented by the committee.
During discussion of the motion, each bylaw is scrutinized by the group, and amended where a majority believes it proper.
(See RONR Section 28, Consideration By Paragraph Or Seriatim.)
Finally, when a majority is in agreement with every section of the bylaws, the vote is taken on their adoption as a whole.
