Hair is a protein filament that grows from follicles found in the dermis, or skin. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair.air is a protein filament that grows from follicles found in the dermis, or skin.

Checks and Balances. The system of checks and balances is an important part of the Constitution. With checks and balances, each of the three branches of government can limit the powers of the others. This way, no one branch becomes too powerful.
Checks and balances prevent any one branch from accumulating too much power and encourage cooperation between branches as well as comprehensive debate on controversial policy issues. For example, to enact a federal law, the Senate and the House of Representatives must each vote to pass the law.
