It's likely a misspelling of "bicameral," which refers to a legislative body composed of two chambers.
Examples of bicameral legislatures include:
* United States Congress: The House of Representatives and the Senate
* United Kingdom Parliament: The House of Commons and the House of Lords
* Canadian Parliament: The House of Commons and the Senate
Therefore, "biocameral" is likely a typo and should be replaced with "bicameral" to accurately describe a legislative body with two chambers.
