A lactic acid test is a blood test that measures the level of lactic acid made in the body. Most of it is made by muscle tissue and red blood cells.
A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter.
Biofuels are designed to replace gasoline, diesel fuel and coal, which are called âfossil fuelsâ because they are made from animals and plants that died millions of years ago. Biofuels are made mostly from plants that have just been harvested. There are three main types of biofuel. Ethanol, biodiesel, and biojet fuel.iofuels are designed to replace gasoline, diesel fuel and coal, which are called âfossil fuelsâ because they are made from animals and plants that died millions of years ago.
