Answer:
Para ser miembro de la cámara baja de un país, por ejemplo, de la cámara de los comunes en el Reino Unido, o de la cámara de representantes en Estados Unidos, éstos deben ganar una elección con el fin de ser elegidos como representantes de un segmento de la población, un segmento que es menos numero que el que es representado por un miembro de una cámara alta, por ejemplo un senador.
Los miembros de las cámaras bajas suelen tener un carácter más local, menos aristocrático, y más popular que los miembros de las cámaras altas. Ésto debido a que en su origen las cámaras bajas fueron desarrolladas con el fin de balancear el poder de las cámaras altas, las cuales estaban dominadas por la aristocracia, el clero, y los poderes económicos.

Despite a high enlistment rate in the U.S. Army, African Americans were not treated equally. At parades, church services, in transportation and canteens the races were kept separate. A quota of only 48 nurses was set for African-American women, and the women were segregated from white nurses and white soldiers for much of the war. Eventually more black nurses enlisted. They were assigned to care for black soldiers. Black nurses were integrated into everyday life with their white colleagues. The first African-American woman sworn into the Navy Nurse Corps was Phyllis Mae Dailey, a Columbia University student from New York. She was the first of only four African-American women to serve as a Navy nurse during World War II.
