Albumin is a protein made by the liver. It makes up about 60% of the total protein in the blood and plays many roles. It keeps fluid from leaking out of blood vessels; nourishes tissues; and transports hormones, vitamins, drugs, and ions like calcium throughout the body.
The Mayan and other Mesoamerican cultures used a vigesimal number system based on base 20 (and, to some extent, base 5), probably originally developed from counting on fingers and toes. The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar.he Mayan civilisation had settled in the region of Central America from about 2000 BCE, although the so-called Classic Period stretches from about 250 CE to 900 CE.
In mathematics and computer science, hexadecimal (also base Template:Num, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0â9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively aâf) to represent values ten to fifteen. For example, the hexadecimal number 2AF3 is equal, in decimal, to (2 Ã 163) + (10 Ã 162) + (15 Ã 161) + (3 Ã 160) , or 10,995.
