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. Wood, crops, and yard and animal waste are examples of biomass.
Clearly, biomass has a long way to go before it's widely accepted as a source of energy. Despite these challenges, there are many advantages to the growing use of biomass energy. One obvious advantage that biomass fuels have over other energy sources is that biomass is renewable: We can grow more plants, but nobody can make more oil. Another advantage is that some sources of biomass, like manure, sawdust, and landfill garbage, use a fuel source that would otherwise go to waste.
