However, when blood glucose levels fall during a long fast, the bodyâs glycogen stores dwindle and additional sources of blood sugar are required. To help make up this shortfall, the liver, along with the kidneys, uses amino acids, lactic acid and glycerol to produce glucose. This process is known as gluconeogenesis.
What is colour blindness? Colour (color) blindness (colour vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. In Britain this means that there are approximately 2.7 million colour blind people (about 4.5% of the entire population), most of whom are male.
As a result, these people see only certain colors and shades. The most common form of color blindness is difficulty in seeing the colors red and green properly, or the same way most people see them. The condition can range from mild to severe. Sometimes a person simply cannot see the colors as vividly as a person who has normal color vision.
