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.
Some kinds of biomass can be burned to produce energy. One common example is wood. Biomass contains stored energy. That's because plants absorb energy from the sun through the process of photosynthesis. When biomass is burned, this stored energy is released as heat. Burning biomass releases carbon dioxide.However, plants also take carbon dioxide out of the atmosphere and use it to grow their leaves, flowers, branches, and stems. That same carbon dioxide is returned to the air when the plants are burned.Many different kinds of biomass, such as wood chips, corn, and some types of garbage, are used to produce electricity. Some types of biomass can be converted into liquid fuels called biofuels that can power cars, trucks, and tractors.hen biomass is burned, this stored energy is released as heat.
