The digestive function of the liver is to produce bile, which is a fat emulsifier. Bile is a yellow-green, alkaline solution containing bile salts, bile pigments (primarily bilirubin), cholesterol, neutral fats, phospholipids, and a variety of electrolytes.he digestive function of the liver is to produce bile, which is a fat emulsifier.

The use of fossil fuels (coal, oil and natural gas) is a problem because the burning of these fuels in industry, transport and the generation of electricity releases carbon dioxide (CO2).This is causing global warming and climate change.: The combustion (burning) of fossil fuels releases poisonous gases into the atmosphere. Oil/Petrol, for instance, is a Hydrocarbon (a mix of Carbon and Hydrogen atoms) and when burnt with Oxygen creates Carbon Monoxide and Carbon Dioxide.
Fossil fuels are energy resources that come from the remains of plants and animals. These remains are millions of years old. There are three fossil fuels: petroleum oil, natural gas, and coal. Fossil fuels, like coal, oil, and natural gas, provide the energy that powers our lifestyles and our economy.Fossil fuels power everything from the planes in the sky to the cars on the road. They heat our homes and light up the night.Theyre the bedrock we base our energy mix on. But they are a limited resource.ossil fuels, like coal, oil, and natural gas, provide the energy that powers our lifestyles and our economy.
