Answer:
Methane is a chemical compound with the chemical formula CH4, symbolizing one atom of carbon and four atoms of hydrogen. It is a group 14 hydride and the simplest alkaline, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Methane naturally occurs both below ground and under the seafloor, and is formed by both geological and biological processes. In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water. Methane is important because it can be captured from landfills, can be burned to produce electricity, heat buildings, or power garbage trucks. Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs. In fact, Jordan Dairy Farms in Massachusetts uses a biodigester to turn cow manure into methane gas, which is used for fuel or turned into electricity.
Answer:
Glycocalyx
Explanation:
Glycocalyx is carbohydrate rich (glycoprotein + glycolipid) coating that is found in outer surface of cell membrane of many prokaryotic and eukaryotic cells specially bacteria.
Glycoprotein=Carbohydrate + Protein
Glycolipids= Carbohydrate + Lipids
Glycocalyx provied a barrier between cell and its surrounding, adhesion and provide protection in bacteria. In eukaryotes it can be used to identify cells.
When we drink less water or we are dehydrated the body will compensate for 1-2% of the total amount of water by creating a sensation of thirst. The kidneys, brain, hormones and glands work in co-ordination monitoring the amount of water consumed to the amount of water lost.
The hypothalamus gland regulates the temperature of our body and balances the processes to control the amount of fluids in body. On detecting less amount of water in blood the hypothalamus gives signals for releasing the anti-diuretic hormone which causes kidneys to remove lesser amount of water from the blood. As a result of this we urinate less and the urine is concentrated dark in appearance. The brain also signals to consume water or liquid to bring the hydration level of the body to normal.
All carbohydrates, including sugar, therefore contain the same three elements:carbon<span>, </span>hydrogen<span> and </span>oxygen<span>.</span>
