A cold is caused by one of many different viruses, some of which are airborne, but most are transmitted by hand-to-nose contact. Once the virus is absorbed by the nose, it causes the body to release histamine, a chemical which dramatically increases blood flow to the nose and causes nasal tissue to swell. This inflames the nasal membranes which become congested with blood and produce excessive amounts of mucus that stuffs up the nasal airway.
Biomass Energy. Biomass is organic material which has stored sunlight in the form of chemical energy. Biomass fuels include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes. Biomass is a renewable energy source because the energy it contains comes from the sun.
Renewable Energy Source. Biomass energy is generated from organic material, plant or animal waste, which is burned to provide energy, e.g. heat & electricity.Since they come from living sources, these products potentially never run out which makes biomass a renewable energy source.educe Landfills. By burning biomass for energy, we can take waste that is harmful to the environment and turn it into something useful. Around six million tonnes of wood is wasted by being sent to landfill in the UK each year. This wood could be used in biomass boilers to heat homes and factories etc.
