What are the disadvantages of biomass?

One of the main disadvantages of using biomass as an energy source is that it can be expensive. Also, biomass energy is inefficient compared to many fossil fuel-based energy sources. It also can be harmful to the environment because using biomass as an energy source emits methane, which is harmful to the Earth's ozone layer. Finally, biomass energy also requires a lot of land. Energy is derived from the combustion of biomass, so many acres of land are necessary to burn biomass each day for fuel.

What is the function of the thalamus?

The thalamus may also be involved in the regulation of some types of memory. The thalamus and the cerebral cortex operate in a feedback loop, especially when it comes to the sleep/wake cycle. The thalamus not only sends signals to the cortex, but the cortex in turn sends signals back to the thalamus. Damage to this system can put a person at risk for irreversible coma.\nAn inherited condition causes the thalamus to degrade over time, leading to insomnia that can prove fatal. A stroke that affects the thalamus can lead to a disorder where the patient feels pain or burning on one side of the bod..

How do I use a scale ruler?

Keep in mind that this number should always be rounded down as it represents the whole feet of the item you are measuring. Next, slide the ruler so that the number you read lines up with the end of the item. The fractional feet to be measured is then represented by the distance from the beginning of the item to the zero point on the scale. Add this reading to the number from earlier to get the full measurement of the item. It is important to know the scale of the item being measured so that the correct scale can be used when measuring with the ruler. For example, 1/8 on the ruler is a scale th..

What are the characteristics of water?

At 1 calorie per gram degrees Celsius, its heat capacity is five times higher than that of aluminum.\nOn account of the hydrogen bonds in the H2O molecule, water has a high boiling point, which makes it turn into water vapor at very high temperatures (212 degrees F). Water is also characterized by capillary action, a phenomenon that occurs when water climbs upward in small spaces, thus defying gravity due to forces of adhesion and surface tension.

What is the lowest temperature on Jupiter?

Jupiter's overall average temperature is -238 degrees Fahrenheit. In the gaseous atmosphere, the temperature can vary by thousands of degrees depending upon the elements present. The temperature also rises based upon the atmospheric pressure, which increases moving toward the planet's core, turning its gases into liquids. At its center, Jupiter can reach temperatures of 36,000 degrees Fahrenheit.

What are the differences between an antigen and an antibody?

Plasma cells, a specific type of B-cells, are responsible for the production of antibodies, reports Wikipedia. An autoimmune disorder can occur when the immune system sends antibodies to attack tissue that is healthy. A B-cell can have more than 50,000 antibodies on its surface; and, these antibodies bind to antigens in large groups. The bind between an antibody and an antigen is reversible.\nThere are several different classifications of antigens, including endogenous antigens, auto-antigens and exogenous antigens. Neoantigens, viral antigens and tumor antigens are also all types of antigens...

Which organs are protected by the rib cage?

The rib cage is one of the strongest structures in the human body, designed to protect two of the most important organ systems: the heart and lungs. It consists of 24 rib bones, along with the sternum, 12 thoracic vertebrae and costal cartilages. The top rib bones are thin, curved bones that connect to the sternum. The lower rib bones connect to the upper rib bones on their costal cartilages, which give them the flexibility to allow a person to breathe.

What are some examples of gases?

Gases can be both crucial and harmful to life. There would be very little life on Earth without air, a gas made of nitrogen, oxygen, carbon dioxide, argon and other gases present in trace amounts. Pain-relieving gases, such as nitrous oxide, made modern medicine possible by allowing patients to undergo long and complex operations. Natural gas, which is a mixture of methane, alkanes and other gases, is used for heating and making fertilizer. Natural gas is also beginning to replace gasoline and diesel as fuels used in transportation.\nThe noble gases, consisting of helium, radon, argon, krypton..

What is the distance traveled by an automobile moving at a constant velocity?

For instance, if a car's constant velocity is 60 miles per hour, it is going in the same direction at that speed for the entire time it is traveling. If the total time traveled is 2.5 hours, the distance is determined by multiplying 60 miles per hour by 2.5 hours to obtain a distance of 150 miles.

What are some limitations of solar energy?

The generation of solar electricity produces no carbon emissions and the power is free after the cost of equipment, but its limitations make it a poor choice for base-line energy generation. Power stations that use coal or natural gas and nuclear plants can adjust their output to generate more electricity as needed, while a solar panel produces a set amount of electricity depending on the intensity of the sunlight that strikes it. Desert areas are best suited to the generation of solar electricity, but transmission losses make it difficult to transport that electricity into regions without sui..
