A hematocrit may be used to: 1  Identify and evaluate the severity of anemia (low RBCs, low hemoglobin, low hematocrit) or polycythemia (high RBCs, high hemoglobin, high hematocrit) 2  Monitor the response to treatment of anemia or polycythemia and other disorders that affect RBC production or lifespan.
Biomass is any organic matter that can be used as an energy source. Wood, crops, and yard and animal waste are examples of biomass.People have used biomass longer than any other energy source. For thousands of years, people have burned wood to heat their homes and cook their food.Biomass gets its energy from the sun.Plants absorb sunlight in a process called photosynthesis.iomass is any organic matter that can be used as an energy source.

Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat. Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels. Examples of biomass and their uses for energy: 1  wood and wood processing wastesâburned to heat buildings, to produce process heat in industry, and to generate electricity. 2  agricultural crops and waste materialsâburned as a fuel or converted to liquid biofuels.
