Explanation:
A bicameral legislature can be defined as a legislative body that comprises of two chambers or houses; upper house and lower house. The upper chamber or house consists of senators while the lower chamber consists of house of representatives.
Generally, the type of government in which legislators such as senators or house of representative members are found is known as a democracy.
A constitution refers to a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens. Basically, the Constitution accords powers to the national or federal government and these includes; enumerated or delegated, reflected, and concurrent powers.
The authors of the Constitution of the United States of America established a bicameral legislature mainly because they reached a compromise between the small states and the large states over representation. This compromise between the large states and the small states was known as the Connecticut Compromise reached during the Constitutional Convention of 1787.
Hence, the counting of slaves and the establishment of a bicameral legislature were issues that were agreed upon in the Constitution of the United States of America.
