biology and human evolution
The earliest human life form can be traced back more than 3.5 billion years ago. Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans. We share many characteristics with these pre-humans. Some of these characteristics include the masters of heredity DNA and RNA as well as proteins composed of amino acids, membranes or bound cells and lastly controlled cell division or mitosis, key to the daughter cells. The diversity of kingdoms is arranged into kingdoms that classify organisms from simple to complex. The traditional five kingdoms are Prokaryote, Protoctista, Fungi, Plantae, and Anamalia. Prokaryote is a bacterium that lacks nuclear membrane. Protoctista is a heterogeneous grouping that combines a great diversity of forms. Fungi are known for being important agents of composition they include yeast and mushroom. Plantae, are categorized as plants that use sunlight to convert to energy. Lastly Anamali

The kidney in the urinary system regulates the chemical composition of the blood thus also regulating the chemical composition of the body tissues. The functional unit of the kidney is known as a nephron and it absorbs much of the soluble nutrient molecules, certain mineral ions and some water. This mixture is also referred to as urine. The urinary bladder then collects this urine from the ureter and stores it for periodic excretion from the body.
